Answer:
10.28571 hp
Explanation:
= Shaft output power = 104 hp
= Average efficiency = 91%
Electric work done rate is given by
The rate of heat supply is given by
The heat supply by the motor to the engine compartment at full load is 10.28571 hp
20/40=0.5 g/cm^3 becuase, mass/volume=density.
Answer:
According to II law of thermodynamics the heat always transfers from high temperature to low temperature body without aid of any external energy. So, according to this law the heat transfers from cup of coffee to the person body until both bodies reaches to the equilibrium state.
After attaining the equilibrium state, the heat transfer may be ceases between the bodies.
Whenever the person touches the hot coffee, he senses the heat that means the heat is transferring in to his body.
Answer: G the speed and direction of the object will remain constant.
