Hi there!
a)
When the motor is first turned on, the coils are initially stationary. Thus, there is no change in magnetic flux and, consequently, no induced emf.
Therefore:
Since there's no back emf:
Solving for i using Ohm's Law:
b)
We are given that at max speed, the back EMF is 70.0 V.
Using the same equation as above:
Plugging in the values:
Solving for current:
Answer:
140525 pa
Explanation:
= depth of water = 4 m
= Area of surface = 8 m²
= Density of water = 1000 kg m⁻³
tex]g[/tex] = acceleration due to gravity = 9.8 ms⁻²
= Atmospheric pressure = 101325 Pa
= Pressure at the given depth "h"
Pressure at the given depth is given as
