The power (in KW) supplied to the starter motor of the large truck is 7.15 KW
<h3>What is power?</h3>
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = voltage (V) × current (I)
P = IV
<h3>How to determine the power</h3>
The power can be obtained as illustrated below:
- Current (I) = 275 A
- Voltage (V) = 26 V
- Power (P) =?
P = IV
P = 275 × 26
P = 7150 V
Divide by 1000 to express in kilowatt (KW)
P = 7150 / 1000
P = 7.15 KW
Thus, the power supplied to the starter motor is 7.15 KW

The unit of the current is Amperes.
Answer:
8.929kg
Explanation:
The work done to place the box at tree house=350 J.
The distance from ground to tree house =4.0 m and
Hence the mass of the box is 8.929kg
Unlike acceleration and velocity, speed does not need to specify the direction of motion. Speed is a scalar quality.
Answer:
An electron has a negative electric charge.
