The planets Mercury and Venus has the closest average temperature
What are Planets?A planet is an astronomical object that orbits a star or stellar remnant that is large enough to be rounded by gravity, but not so large as to trigger thermonuclear fusion, and that is free of planetesimals in its locality
Planets are generally divided into two main types: large, low-density gas giants and smaller, rocky terrestrials.
In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune
Given data ,
Let the first planet be represented as A
Let the second planet be represented as B
Now , the planets A and B have similar average temperature
where , the planets can have negative as well has very high temperatures
Now , when A = Mercury and B = Venus
Venus has 864 degrees Fahrenheit (462 degrees Celsius)
And , Mercury has 800 degrees Fahrenheit (430 degrees Celsius)
So , both Venus and Mercury has similar temperatures
Now , when A = Neptune and B = Uranus
Neptune has minus 353 degrees Fahrenheit (minus 214 degrees Celsius)
Uranus has minus 374 degrees Fahrenheit (minus 224 degrees Celsius)
So , both Neptune and Uranus has similar temperatures
Hence , the planets are Venus and Mercury

A .63 kg ball is moving at 4.3m/s. What is the momentum of the ball?
Answer:
Given Mas (m) =63kg
velocity (v) =4.3m/s
momentum (p) =?
p=mv
63kgx4.3m/s
270.9kg.m/s
the momentum =270.9kg.m /s
If a ball of mass 0.63 kilograms is moving at 4.3 meters/seconds, then the momentum of the ball would be 2.709-kilogram meters/second.
What is momentum?It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle.
Momentum = mass of the object × velocity of the object
As given in the problem we have to calculate the momentum of the ball if it has a mass of 0.63 kilograms and moving with a speed of 4.3 meters/seconds,
The momentum of the ball = 0.63× 4.3
=2.709 kilogram meters/second
Thus, the momentum of the ball comes out to be 2.709-kilogram meters/second.

Answer:
A: Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that’s above the ball. Slip an end of the string through the hole, and tie a knot. This is your pendulum. Hold the loose end of the string still with one hand. With the other hand, raise the ball in an arc so that it’s almost level with the hand holding the string. With the string taut, let the ball go. What do you observe?
Mine was swaying perfectly fine. after a little bit it gradually started swinging slower until stopped.
B: Why did the pendulum stop swinging? Where did the energy go?
gravity was pulling it towards the ground, however the weight and momentum of the ball helped it keep swinging for a good while.
C: Scientists have organized all forms of energy into two types—kinetic and potential. Kinetic [THE ENERGY OF MOTION IN A BODY] energy is the energy of motion, and potential energy [THE STORED ENERGY IN AN OBJECT] is stored energy. At the top of its swing, does the pendulum have kinetic or potential energy?
when its at the very top of the swing it does have a very small amount of time until it starts going back down again but during that time it is potential energy
D: At the bottom of its swing, does the pendulum have kinetic or potential energy?
the pendulum still has kinetic energy when it is the closest to the ground since it is still swinging
E: Think about the process of raising the pendulum to one side and letting it go. For this event, create a list of each form of energy associated with the pendulum as it cycles.
when its in my hand: potential energy
when it starts swinging: kinetic energy
when its going upwards: kinetic energy
when it stops swinging: potential energy
F: How could you give the pendulum more energy?
one way you could possibly make it have more energy is if you make the string longer
G: Now raise the pendulum and let it hit a metal lid or pan. When the ball strikes the lid, what forms of energy can you identify?

A small difference between means may not be statistically significant, but it could reach statistical significance with a large sample becausea) As N increases, the standard error gets smaller, reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences.b) As N increases, distributions get more heterogeneous, allowing small differences to be detected.c) The overlap between distributions grows as sample size increases.d) The difference between means gets larger as sample size increases
Answer:
Increasing the sample size could make a small difference between means reach statistical significance because;
a) As N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences
Explanation:
The p-value of a test statistic is used to express the level of significance of the test result. A significant result is typically considered as one with a small p-value of less than or equal to 0.05 at which point we reject the null hypothesis
The p-value can be made smaller by either
1) Increasing the size of the sample (N)
2) Decreasing the standard error
3) Increasing the difference between the hypothesized parameter and the statistic of the sample
The standard error, SE, is given as follows;
[tex]SE = \dfrac{\sigma}{\sqrt{N} }[/tex]
Where;
σ = The standard deviation of the sample
n = The sample size
Therefore the standard error decreases, gets smaller, with increasing sample size, N
Therefore, the small difference between the sample mean could reach statistical significance with a large sample because as N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences.

What happens to the temperature of an air mass as it rises, and why? What happens to the temperature of an air mass as it rises, and why? Temperature increases because fewer air molecules allow the air mass to expand. Temperature decreases because increasing numbers of air molecules allow the mass to expand. Temperature increases because more air molecules force the air mass to contract. Temperature decreases because fewer air molecules allow the air mass to expand. Temperature remains the same because fewer air molecules allow the air mass to expand.
Answer:
Temperature decreases because fewer air molecules allow the air mass to expand.
Explanation:
Temperature of air mass decreases as it rises . It is so because at upper strata
of atmosphere , air is sparse and therefore air molecules there is relatively less . It results in lower pressure around air mass going up . This results in expansion of gas . Molecules have to do work against mutual attractive force for expansion so their energy becomes less . This cools down the air.

A business jet of mass 24000kg takes off when the thrust for each of two engines is 34000N. Find the acceleration.
Answer:
1.42 m/s²
Explanation:
From the question,
F = ma.................... Equation 1
Where F = force, m = mass of the jet, a = acceleration of the jet
make a the subject of the equation
a = F/m................. Equation 2
Given: F = 34000 N, m = 24000 kg
Substitute into equation 2
a = 34000/24000
a = 1.42 m/s²
Like all planets, the planet Venus orbits the Sun in periodic motion and simultaneously spins about its axis. Just as on Earth, the time to make one complete orbit (i.e., the period of orbit) is what defines a year. And the time to make one complete revolution about its axis (i.e., the period of rotation) is what defines a day. The period of orbit for the Earth is 365.25 days and the period of rotation is 24 hours (1.00 day). But when these same values for Venus are expressed relative to Earth, it is found that Venus has a period of orbit of 225 days and a period of rotation of 243 days. So for Venus inhabitants, a day would last longer than a year! Determine the frequency of orbit and the frequency of rotation (in Hertz) on Venus. Ans: A marine weather station detects waves which are 9.28 meters long and 1.65 meters high and travel a distance of 50.0 meters in 21.8 seconds. Determine the speed and the frequency of these waves. Ans:
Answer:
a) F = 5.14 10⁻⁸ Hz, f = 4.76 10-8 Hz, b) v = 2.29 m / s, f = 42.5 Hz
Explanation:
a)This problem has two parts.
For the calculations relative to the planet Venus, we use that the period and the frequency are related
f = 1 / T
frequency of the orbit around the Sun
Let's reduce the period to the SI system
T = 225 days (24h / 1days) (3600 s / 1h) = 1.94 10⁷ s
F = 1 / 1.94 10⁷
F = 5.14 10⁻⁸ Hz
rotation frequency
T = 243 d = 2.1 107 s
f = 1 / T
f = 1 / 2.1 107
f = 4.76 10-8 Hz
b) give the data of some marine waves
the speed of the wave can be found with kinematics
v = x / t
v = 50.0 / 21.8
v = 2.29 m / s
If the wavelength is L = 9.28m
this distance is the distance between two consecutive ridges or valleys
λ / 2 = L
λ = 2L
λ = 2 9.28
λ = 18.56 m
the speed of the wave is
v = λ f
f = v /λ
f = 2.29 / 18.56
f = 42.5 Hz
Which of these is a unique use of gamma radiation?
A. Detection of thyroid cancer
O B. CT scanners
C. Smoke detectors
D. Killing bacteria
SUBMIT
Who knows
Answer:
the answer would be 'd'
Explanation:
im really good at this stuff
The unique use of gamma radiation is Killing bacteria. The correct option is D.
What is gamma radiation?Gamma radiation is a type of electromagnetic radiation that is highly energetic and has no mass or charge. It is the most penetrating form of radiation and is often emitted during radioactive decay or nuclear reactions. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum, ranging from about 0.1 nanometers to 10 picometers in wavelength. They can cause ionization in matter, meaning they can knock electrons out of atoms or molecules, making them highly damaging to living tissue. Gamma radiation is commonly used in medical imaging and cancer treatment, as well as in industrial applications for sterilization and food preservation.
Here in the Question,
Option A. Detection of thyroid cancer: Gamma radiation is used in medical imaging techniques such as PET scans and SPECT scans to diagnose cancerous conditions, but it is not unique to the detection of thyroid cancer.
Option B. CT scanners: Gamma radiation is not used in CT (computed tomography) scanners. CT scanners use a series of X-rays to produce detailed images of the inside of the body.
Option C. Smoke detectors: Smoke detectors use a small amount of radioactive material, typically americium-241, to ionize air particles and detect the presence of smoke. While gamma radiation is a type of ionizing radiation, smoke detectors do not use gamma radiation specifically.
Option D. Killing bacteria: Gamma radiation is used in the food industry to kill bacteria and sterilize food products, such as spices, meat, and poultry. This is a unique use of gamma radiation, as it relies on its ability to destroy microorganisms at high doses while leaving no residual radiation.
Therefore, The correct answer is option D i.e Killing bacteria.

can a body have zero velocity and finite acceleration?Explain
Answer:
Kinda? Depends what the question is fully asking
Explanation:
Acceleration is a change in velocity. So I guess if the velocity of something is -2 m/s and its positively accelerating at a value of +1 m/s, then that means every second its velocity changes by +1m/s.
So that -2 m/s thing after one second will be going -1 m/s.
After another second it'll be going 0 m/s.
After another itll be going +1 m/s and so on.
So at one point for a brief moment, it can have an acceleration but be at 0 m/s velocity.
Small pieces of sand hitting the side of a mountain and weathering the rock is an example of what type of weathering?
Answer: This is MECHANICAL type of weathering.
Explanation:
Weathering is defined as the process by which rocks breakdown into smaller quantities due to different atmospheric and biological activities.
There are different types of weathering which include:
--> MECHANICAL WEATHERING: This type of weathering is also called physical weathering. Here, rocks are being broken down into smaller pieces but the mineral composition of the rock remains the same. This type of weathering can occur in two ways:
• By Ice wedging: this is one of the easiest ways rocks can be broken into smaller pieces. It occurs at the earth polar regions (climate that regularly cycles above and below the freezing point) and in areas of higher elevations such as the mountains. Ice wedging of rocks occurs when water seeps into cracks, it freezes and expands. This results in wedging (splitting) the rocks apart with repeated freezing.
• By Abrasion: this is another form in which mechanical weathering occurs. Abrasion occurs when strong winds carrying pieces of sand sandblast mountain surfaces. Also moving water, gravity, biological activities can cause abrasion of rock surfaces leading to its weathering.
Therefore, small pieces of sand hitting the side of a mountain and weathering the rock is an example of mechanical weathering by abrasion.
