The correct answer would be 2: they transfer energy.
Answer:
TA is greater than TB
> 
Explanation:
Specific heat at constant pressure 
is greater than specific heat at constant volume 
.Therefore for given amount of supplied heat,increase in temperature at constant volume is greater than increase in temperature at constant pressure
Hence
TA is greater than TB

Answer:
Explanation:
Equation for translational kinetic energy = 1/2 m V² where m is mass and V is velocity .
In first case let mass of car be m
Translational kinetic energy = 1/2 m x 40² = 800 m .
In the second case ,
Translational kinetic energy = 1/2 m x 20² = 200 m
So , in former case kinetic energy of car is 4 times that of second case.
Answer:
<h2>2500 J</h2>
Explanation:
The average kinetic energy can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer is
<h3>2500 J</h3>
