4. An object is moving with an initial velocity of 9 m/s. It accelerates at a rate of 1.5

Mazyrski [523]

Answer:

11.87 ms⁻¹

Explanation:

You can use the kinematic equation

v² = u² + 2as

Where v = final velocity

u = initial velocity

a = acceleration

s = displacement

v² = 9² + 2×1.5×20

So you get v = 11.87 ms⁻¹

A coil consisting of 50 turns of wire is powered by a 9V battery. If the coil draws 1.5 A from the battery, what is the MMF, in

aivan3 [116]

A. 75 ampere-turns

<u>Explanation:</u>

Given:

Number of turns, n = 50

Voltage, V = 9V

Current, I = 1.5A

MMF= ?

MMF is magnetomotive force.

MMF is independent on voltage and dependent on the number of turns and current in the wire.

Thus, MMF can be written as:

$MMF = nI$

On substituting the value we get:

MMF = 50 X 1.5

MMF = 75 ampere-turns
