Answer:
The increase in thermal energy results in an increase in pressure.
Explanation:
- The increase in entropy is directly related to the increase in temperature. So the thermal energy in heat engine increases the temperature of that surrounding.
- Higher temperature means the kinetic energy of particles is also higher, their vibration is increasing. So it increases the pressure (ideal gas law).
- In this way the increment in the thermal energy in heat engine moves piston by increasing the pressure.
Answer:
After 9 seconds the object reaches ground.
Step-by-step explanation:
We equation of motion given as h = -16t²+128t+144,
We need to find in how many seconds will the object hit the ground,
That is we need to find time when h = 0
0 = -16t²+128t+144
16t²-128t-144= 0
Negative time is not possible, hence after 9 seconds the object reaches ground.
Internal energy cannot be transferred whereas, thermal energy is the energy due to temperature difference
Internal and external combustion engines are two types of heat engines: they convert thermal energy into mechanical energy. The main difference between internal and external combustion engine is that in internal combustion engines, the working fluid burns inside the cylinder, whereas in external combustion engines, combustion takes place outside the cylinder and heat is then transferred to the working fluid.
Answer:
262.5 Nm
Explanation:
Torque is the rate of change of angular momentum.
Hence, we have
Δ<em>L</em> is the change in angular momentum.
Using values in the question,
