The railroad tracks will move with the plate boundaries
Answer:
Current = 132.35 A
The motor needs to draw 132.35 Amperes current from the battery.
Explanation:
The formula of electric power is given as follows:
Power = (Voltage)(Current)
Current = Power/Voltage
In this question, we have:
Power = 45 KW = 45000 W
Voltage of Battery Pack = 340 V
Current needed to be drawn = ?
Therefore,
Current = 45000 W/340 V
<u>Current = 132.35 A</u>
<u>The motor needs to draw 132.35 Amperes current from the battery.</u>
Answer:
The formula is dimensionally correct.
Explanation:
Given

Prove its correctness
Write out the dimension of each:
--- displacement
--- velocity * time
--- acceleration * square of time
The expression becomes:


Apply law of indices



Both sides of the equation are equal
