Why do temperatures on the moons surface vary ncyb more than temperatures on earth
The moon has a lord density than earth
The moons surface has more craters than earth
The moon has no atomsphere
The moon is farther from the sun compared to earth
Answer:
The moon has no atmosphere
Explanation:
The temperatures on the surface of the Moon vary much more than those on Earth because the moon has no atmosphere (third answer in the list), and therefore there are no molecules that could retain residual heat and make the change from day to night a softer transition.
Water of mass 100 g at a temperature of 100 °C is converted into steam at 100 °C. The specific
latent heat of vaporisation of water is 2300 J/g.
How much thermal energy is absorbed by the water?
0 230 000
0 23 000 000 J
0 230 J
O 23 J
Answer:
The thermal energy absorbed by the water is 230,000 J.
Explanation:
Given;
mass of the water, m = 100 g
The specific latent heat of vaporization of water, L = 2300 J/g
temperature of the steam, θ = 100 °C
The thermal heat capacity or thermal energy absorbed by the water is calculated as follows;
H = mL
H = 100g x 2300J/g
H = 230,000 J
Therefore, the thermal energy absorbed by the water is 230,000 J.

People living near wind farms sometimes object to them because of visual pollution and what other
form of pollution?
Answer:
Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as "annoying." They claim this nuisance negatively impacts their quality of life
Another form of pollution in the farm is called noise pollution
Noise pollution is simply known as disturbing or elevated sound that constitute nuisance and affects the health and well-being of people.Noise pollution from farm includes animals making different sounds, sounds from farm machineries and farm equipment etc.Conclusively, we can say that another form of pollution in the farm is called noise pollution

Why do we add the masses together after that inelastic collision?
Answer:An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). A collision in which the objects stick together is sometimes called perfectly inelastic because it reduces internal kinetic energy more than does any other type of inelastic collision.People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.

A boy pushes his baby sister in a stroller that has a mass of 45,000 g. What is the acceleration on the stroller if the force is 65 N?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Force.
Force = Mass * Acceleration.
here, Mass = 45 kg and Force = 65 N
hence, Acceleration = 65/45
===> Acc. = 1.44 m/s^2
hence the acceleration is 1.44 m/s^2

There is a bell at the top of a tower that is 45m high. The bell mass is 190. Calculate its potential energy.
Answer:
83790 J.
Explanation:
Potential Energy: This can be defined as the energy possessed by a body, by vitue of it position in the gravitational field. The S.I unit of Potential Energy is Joules (J).
From the question,
P.E = mgh........................................... Equation 1
Where P.E = potential Energy of the bell, m = mass of the bell, h = height of the tower, g = Acceleration due to gravity.
Given: m = 190 kg, h = 45 m.
Constant: g = 9.8 m/s²
Substitute these values into equation 1
P.E = 190×45×9.8
P.E = 83790 J.
Hence the potential energy of the bell is 83790 J.

The compass is a small bar magnet that’s free to spin. Based on what you observed, is the coil of wire with current passing through it a magnet?
Answer:
People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia—the name of this region is the source of words like magnet. Magnetic rocks found in Magnesia, which is now part of western Turkey, stimulated interest during ancient times. When humans first discovered magnetic rocks, they likely found that certain parts of these rocks attracted bits of iron or other magnetic rocks more strongly than other parts. These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.
A bar magnet with paper clips attached to it.
Figure 20.2 A bar magnet with paper clips attracted to the two poles.
If a bar magnet is suspended so that it rotates freely, one pole of the magnet will always turn toward the north, with the opposite pole facing south. This discovery led to the compass, which is simply a small, elongated magnet mounted so that it can rotate freely. An example of a compass is shown Figure 20.3. The pole of the magnet that orients northward is called the north pole, and the opposite pole of the magnet is called the south pole.
Answer:
Yes, the coil of wire with current passing through it is a magnet.

If a car is traveling 103 miles per hour, how many miles and how much time would it take for another car to catch up to them from a complete stop?
Answer:
Required distance is 103 miles and the required time is 1 hour
Explanation:
Given;
speed of the car, v = 103 miles per hour
Speed is the given as the ratio of distance traveled to time taken for the motion.
The distance it will take another car to catch up to them from a complete stop is 103 miles and the time it will take the car is 1 hour.
Therefore, required distance is 103 miles and the required time is 1 hour.

What is the energy required to change 600g of liquid into steam if the specific heat latent is 4000 J/kg
Answer:
2400 J
Explanation:
Latent heat: This is also called hidden heat, it is the heat that is not detectable by the thermometer.
From the question,
Q = cm.................. Equation 1
Where Q = Energy, c = specific latent heat of the liquid, m = mass of the liquid.
Given: c = 4000 J/kg, m = 600 g =( 600/1000) kg = 0.6 kg
Substitute these values into equation 1
Q = 4000×0.6
Q = 2400 J
Hence the energy required is 2400 J

A string can withstand a force of 135 N before breaking. A 2.0 kg mass is tied to the string and whirled in a
horizontal circle with a radius of 1.10 m. What is the maximum speed that the mass can be whirled at before
the string breaks?
The mass would have centripetal acceleration a given by
a = v ² / R
where
v = tangential speed of the mass
R = length of the string
By Newton's second law, a maximum tension of F = 135 N would apply an acceleration of
135 N = (2.0 kg) a → a = 67.5 m/s²
which requires a tangential speed v of
67.5 m/s² = v ² / (1.10 m) → v = √((67.5 m/s²) (1.10 m)) ≈ 8.62 m/s

Why did you need a permanent magnet? What do you think would happen if you increased the
number of permanent magnets? (dc motor)
Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.
Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.

One of the most prominent legacies of the games is Centennial Olympic Park in the heart of Atlanta. The 21-acre plaza glistens in what was an area of urban decay, and children run and linger in the fountain.
Harvey Newman, a professor of public policy at Georgia State University, says the park brought economic development downtown.
"The area surrounding the park has added major hotels, condominiums, new office structures and, of course, people continue to flock to enjoy the Olympic rings fountain," Newman says.

Describe the importance of conservative forces to conservation of energy.
Answer:
IF a force is conservative, it is possible to assign a numerical value for the potential at any point and conversely, when an object moves from one location to another, the force changes the potential energy of the object by an amount that does not depend on the path taken, contributing to the mechanical energy and the .
