Answer:
= 8.5264
Explanation: Power is the rate of energy transferred per unit of time: P = 
The energy from the engine is converted into kinetic energy, which is calculated as: 
To compare the power of the two cars, first find the Kinetic Energy each one has:
<u>K.E. for Model A</u>

<u>K.E. for model B</u>


Now, determine Power for each model:
<u>Power for model A</u>
= 
<u>Power for model B</u>

Comparing power of model B to power of model A:

8.5264
Comparing power for each model, power for model B is 8.5264 better than model A.

Answer:
the light creates sorta a mixture of all the colors on the white index card.
A- electrical energy to kinetic energy
I think the answer would be A. Density because many headlights could have the same density, but the rest of the analysis techniques would be specific to that crime.
Answer:

Explanation:
Given that,
Efficiency of heat engine, 
Temperature of hot source, 
We need to find the temperature of cold sink i.e.
. The efficiency of heat engine is given by :




So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
