Which of the following is not an example of kinetic energy? mechanical energy nuclear energy electrical energy thermal energy

It is only mechanical energy that is kinetic energy while the other choices are not kinetic energy. Nuclear, electrical and thermal are other types of energy. Hope this answers the question. Have a nice day. Feel free to ask more questions.

In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star? Express your answer (a)in kilograms and (b)as a multiple of our sun's mass.

  I'll tell you how to do it but you must crunch the numbers. 

Use Kepler's 3rd Law 

T^2 = k R^3 

where k = 4(pi)^2/ GM 
G =gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2 
M = mass of this new planet 
pi = 3.14159265 
T =3.09 days = 266976 seconds 
R = (579,000,000km)/9 = 64333333.3 km 

a) 
Solve Kepler's 3rd Law for M. Your answer will be in kg 


b) 
mass of the sun = 1.98892 × 10^30 kilograms 
Form the ratio 
M(planet)/M(sun)

Explain Why must a cooling system do work to transfer thermal energy?

Although internal energy will not spontaneously flow from a cold region to a hot region, it can be forced to do so by doing work on the system.Refrigerators and heat pumps are examples of heat engines which cause energy to be transferred from a cold area to a hot area. Usually this is done with the aid of a phase change, i.e., a refrigerant liquid is forced to evaporate and extract energy from the cold area. Then it is compressed and forced to condense in the hot area, dumping its heat of vaporization into the hot area. ARE YOU FROM K12?

Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy

When we say potential energy, this is the energy at rest. And kinetic energy is the energy at motion. So, here are the examples of energy that is transforming from potential energy to kinetic energy: changing thermal energy to electrical energy, and changing radiant energy to electrical energy. Hope this answer helps.

If two carts collide, what type of collision will conserve both momentum and kinetic energy? a. head on b. perfectly inelastic c. none d. perfectly elastic

The appropriate answer is d. perfectly elastic. When a perfectly elastic collision occurs both momentum and kinetic energy are preserved. Momentum is the mass of an object times its velocity while kinetic energy is the energy that a moving object has due to its motion. In an elastic collision kinetic energy would be converted to some other form of energy.

A satellite in space experiences direct sunlight and heats up. During periods when it receives not direct sunlight, what happens

It tries to maintain the normal temperature of the metals used.
There are two ways the Scientific and the Normal.( for a lack of better word)
Normal: The heat escapes into space.
Scientific: As the molecules of the element heat up and vibrate for long periods they lose heat so they return to their original temperature (at least try to)

Why doesn't an electromagnetic wave move as fast through a solid as it would a gas

Because in a solid the atoms are a lot closer together, and depending on the size, a lot more of them. In gas, there is in fact more atoms, but they are not as close together, making it easier of the waves to travel along.

When would the temperature and thermal energy of an object differ?

The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.

A laser produces 20.0 mW of red light. In 1 hour, the laser emits 2.29 X 10^20 photons. What is the wavelength of the laser?

Using Planck's equation,

E = nhc / λ

Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J

108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m

Which makes fast-moving water a greater force of erosion? A. greater heat capacity B. greater energy C. increased density D. greater oxidation

Answer:

B. Greater energy

Explanation:

Fast moving water is very energetic as its can displace very large rocks, boulders and make pebbles and sand out of them through the process r erosion. Fast moving water have kinetic energy, it opposes anything that come in its way. As river make its own channel by eroding plane. Many antecedent rivers have make their channel by cutting large mountains too.
