Answer: Technician B
Explanation: In manual cars,the clutch safety is designed to stop the vehicle from moving when you start the gnition. It prevents power from flowing into the circuit . This is found in the pedal mechanism of cars so depressing the clutch pedal will likely cause a defective in the clutch safety. You will begin to perceive the clutch burning and white fumes coming out from the pedal.
Applying the first law of thermodynamics, we know that the heat transferred is equivalent to the work done and the internal energy of the bodies.
In mathematical terms this can be expressed as
According to the statement, the work is carried out on the substance, therefore, the work will be negative (by convention)
Therefore 2700Btu were added as heat to the substance.
The value per unit of mass would be
Therefore it was added around to 54Btu/lbm
Answer:
Hence the distance covered by the object is 80m
Explanation:
D. Electromagnet Induction
Answer: momentum = mass × velocity; and is a vector quantity. Newton's 2nd Law : Fnet=ma. (1). so we have. F=28N. u=0ms−1. v=55ms−1. t=3s.
Explanation: we need the following results momentum = mass×velocity; and
