Answer:
scalar,magnitude
Explanation:
scalar is an example of length/distance
magnitude is the length of a vector
D. The maximum electromotive force induced in the coil is determined as 3,200 V.
<h3>
Maximum electromotive force induced in the coil</h3>
emf(max) = NAB/t
where;
- N is number of turns
- B is magnetic field
- A is area of the coil
- t is time
Substitute the given parameters and solve for emf
emf(max) = (150 x 0.042 x 0.86) / (1.7 x 10⁻³)
emf(max) = 3,187.1 V
emf(max) ≈ 3,200 V
Thus, the maximum electromotive force induced in the coil is determined as 3,200 V.

Answer:
<em>The velocity of the camera just before it hit the ground = 35.97 m/s.</em>
Explanation:
Velocity: This can be defined as the ratio of the displacement of a body to the time. Velocity is a vector quantity, and as such it can be represented both in magnitude and direction.
From the equation of motion,
v² = u² + 2gs ................ Equation 1
Where v = final velocity, u = initial velocity, g = acceleration due to gravity, s = distance.
Note: Before the velocity of the camera before it hits the ground = The final velocity of the camera.
<em>Given: u = 10.8 m/s, s = 60 m. g = 9.81 m/s.</em>
<em>Substituting into equation 1,</em>
<em>v² = 10.8² + 2(9.81)(60)</em>
<em>v² = 116.64+1177.2</em>
<em>v² = 1293.84 </em>
<em>v = √(1293.84)</em>
<em>v = 35.97 m/s.</em>
<em>Hence the velocity of the camera just before it hit the ground = 35.97 m/s.</em>
