Katena32 [7]2 years ago
6 0
The unit of power is called Watts.
1 way to calculate power is to divide Energy (in joules) by Time (in seconds)

Convert 4kJ to J by multiplying 4x1000

J = 4000

W = E/t

W = 4000J / 0.5s

W = 8000

Electro produced 8000 watts.

Answer:

Both technicians are correct

Explanation:

In automobiles, governors are being used. Governors are also known for speed limiters as they can regulate and measure the speed of the automobile.

Hydraulic Transmission: Shifting is controlled by mechanical sensors according to vehicle speed and throttle position/manifold vacuum through valving operated by hydraulic 'pilot' signals.

Electronic Transmission: Shifting is controlled by an on-board computer that receives signals from electronic sensors.
