Answer:
Workdone = 1.96 Nm
Explanation:
Given the following data;
Mass = 100g to kg 100/1000 = 0.1Kg
Distance = 2m
To find the workdone;
First of all, we would determine the force acting on the apple
Force = mass * acceleration due to gravity
But, acceleration due to gravity is equal to 9.8m/s²
Force = 0.1 * 9.8
Force = 0.98N
Now, we can find the workdone using the formula;
Workdone = force* distance
Substituting into the equation, we have
Workdone = 0.98 * 2
Workdone = 1.96 Nm
How can you defined work done in term of kinetic energy, potential energy, and the force?

A canoe moving down the river with a kinetic energy of 5J and a speed of 0.5m/s. What’s the mass of the canoe
What is the speed of a 180 g ball if its kinetic energy is 100 J?
Answer:
Velocity, V = 33.33 m/s
Explanation:
Given the following data;
Mass = 180grams to kilograms = 180/1000 = 0.18 kg
Kinetic energy = 100J
To find the speed;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
100 = ½*0.18*V²
Cross-multiplying, we have;
200 = 0.18*V²
V² = 200/0.18
V² = 1111.11
Taking the square root of both sides, we have;
Velocity, V = 33.33 m/s

Explain in detail what you would experience
throughout the year if the axis of the Earth was not
tilted.
Explanation:
Scientists think an Earth without a tilt would be stratified into climate bands that would get progressively colder as you moved away from the equator. Humans would never survive the continuous winter of the high latitudes, and so we would likely congregate in the planet's tropical midsection.

The pole star can be located using the Ursa Major constellation, by imagining a line towards the Northern direction connecting two stars present at the end of the bowl, This imaginary line meets Pole Star. The length of the imaginary line from the bowl is about five times the distance between the two stars of the bowl.
Explanation:
Use Gauss's Law to find the electric field produced by an infinite plane of uniformly distributed charge Q, with charge density σ. Draw the appropriate Gaussian Surface
Answer:
Explanation:
Consider an endless sheet of uniform charge thickness per unit area [tex]\sigma[/tex]
For a boundless sheet of charge, the electric field will be opposite to the surface. In this way, just the closures of a round and hollow Gaussian surface will add to the electric transition. For this situation, around and hollow Gaussian surface opposite to the charge sheet is utilized. The subsequent field is a large portion of that of a conductor at harmony with this surface charge thickness.
By balance, we expect the electric field on one or the other side of a plane to be an element of x just to be guided typical to the plane and to point away from/towards the plane contingent upon whether, [tex]\sigma[/tex] is positive/negative.
According to the law;
[tex]2EA = \dfrac{q_{enc}}{\varepsilon_o}[/tex]
[tex]where; \ q_{enc} = total \ enclosed charge = \sigma A \\ \\ thus; \\ \\ 2EA = \dfrac{\sigma A}{\varepsilon_o} \\ \\ E = \dfrac{\sigma}{2 \varepsilon _o}[/tex]
Your student desk has been in the room for many hours, it is at thermal equilibrium with the room?
Which part of your desk is colder: the wood or the metal? Why?
Answer:
metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.
Explanation:
describe the steps that occurs in the process of fission
Answer:
--In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. -- In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.
OR
Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and releases more neutrons. The neutrons hits the nuclei of more atoms, splitting them and releasing more energy and neutrons.

A car travels at 12 m/s. The car then accelerates at 3 m/s2 until it reaches a speed of 18m/s.
Use the formula: (final velocity)2 – (initial velocity)2 = 2 x acceleration * distance
Calculate the distance the car travels.
A
2 m
B
6 m
С
30 m
D
60 m
Answer:
С. 30 m
Explanation:
Given the following data;
Initial velocity, U = 12m/s
Final velocity, V = 18m/s
Acceleration, a = 3m/s²
To find the distance, we would use the third equation of motion;
V ² = U² + 2aS
Substituting into the equation, we have
18² = 12² + 2*3*S
324 = 144 + 6S
6S = 324 - 144
6S = 180
S = 180/6
Distance, S = 30 meters.
Which equation determines the acceleration of an object moving in a straight line?
You must calculate the change in speed per unit of time.
Group of answer choices

A 500g glass statue is accidentally knocked from a shelf 1.5m high. If 3% of the gravitational potential energy is converted into heat, how much does the statue’s temperature rise
Answer:
0.0001158443168226212 Celcius (significant digits? who cares.....) or about 0.00021 Fahrenheit
Explanation:
500g=0.5kg
PE=mgh
PE=(0.5)*(9.81)*(1.5)
PE=7.36J
3% of 7.36 is 0.22J is converted to heat
From there, it's tricky.
I just used a joules to celcius converter to get 0.0001158443168226212 degrees celcius or 0.00021 degrees fahrenheit rise in temp.

Explanation:
Shrill sound is of -------------- *
Higher frequency
Lower frequency
Higher amplitude
Lower amplitude
Answer:
Higher frequency.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.
Mathematically, the speed of a sound is given by the formula:
[tex] Speed = wavelength * frequency [/tex]
Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.
A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.
Hence, shrill sound is of higher frequency.

how are electromagnetic waves produced
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.
The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).
Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.
Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

Denver, Colorado is located near the rocky mountains. Which list of controls below would have the strongest influence on the weather in Denver.
A ) Ocean currents, distance from large bodies of water, and altitudes
B ) Altitude, topography, and ocean currents.
C ) Latitude, altitude, and topography
D ) Topography, ocean currents, and latitude.
Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.
Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.
