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.

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.

What happens when the temperature of an object increases? A. The particles move closer together. B. The particles move faster. C. The number of particles increases. D. The particles stop moving.

I believe the correct answer from the choices listed above is option B. When the temperature of an object increases, the particles move faster since kinetic energy of the molecules increases. Hope this answers the question. Have a nice day.

How do plant and animal cells function differently

Although, the overall function of the cell is the same, there are some important differences between animal and plant cells. The first difference is that plant cells have an organelle called chloroplast. Chloroplasts contain a pigment called chlorophyll (which gives the plant its green color).

Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.The lysosomes are the animal cell's "garbage disposal", while in plant cells the same function takes place in vacuoles.Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

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?

A car starts from xi = 12m at ti = 0 and moves with the velocity graph shown in figure below. What is the objects position and t=3s and t=4s? Picture in comments below

Our starting velocity is V0 = 12m/s

There are 2 ways of solving this question
First is to use formula which connects starting speed, acceleration (which we would calculate from graph where we can see how speed changes) and time to calculate traveled distance.

S = V0 * t + 1/2*a*t^2

acceleration a is a = -4m/s^2

S(t=3s) = 18

On this value we add 12 initial meters of distance and we get S(t=3s) = 30 meters

For t=4s we get

S = 16 m

Plus initial distance of 12 m we get 30 meters

Answers are 30 and 28 meters.

------------------------------------------
second way is to find surface of graph bellow speed line for 3 and 4 seconds...

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.

Please help! Find the tension in each cord in the figure if the weight of the suspended object is w = 210N A) Find the tension in the cord A for system (b). B) Find the tension in the cord B for system (b).

We have to solve the system of equations:
- T a * cos 60° + T b * sin 45° - 210 N = 0
- T a * sin 60° + Tb cos 45° =  0
------------------------------------------------------
- 1/2 T a + √2 / 2 T b = 210 N
- √3 / 2 T a + √ 2 / 2 T b = 0     / * ( - 1 )
---------------------------------------------------
- 1/2 T a + √2 / 2 T b = 210 N
√ 3 / 2 T a - √2 / 2 T b = 0
----------------------------------------
T a ( √3 / 2 - 1 / 2 ) = 210 N
0.366 T a = 210 N
T a = 210 N : 0.366
1 ) T a = 573.77 N
Ta * √3 / 2 = T b * √ 2 / 2
T b = ( 573.77 * 1.732 ) : 1.4142
2 ) T b = 702.7 N

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.

What's the difference between an axon and a dendrite

Dendrites are the fine branches from the cell body that receive incoming information from other neurons and transmit it to the cell body. 
Axons on the other hand transmit information from the cell body  to other neurons or to cells in glands and muscles. This would make a bit more sense if you take a look at a structure of the neuron.

What causes the electric charges to flow from one end of the battery to the other? a balance in electric potential a balance in resistance a difference in electric potential a difference in resistance

The answer is difference in eletric potential. If there are 2 groups of electric potential and they are connected, the difference in potential we cause particles with charge to flow until the potential is equal. Resistance only determines rate of flow but doesnt initialy cause the flow.
