A survey team is trying to estimate the height of a mountain above a level plain. from one point on the plain, they observe that
the angle of elevation to the top of the mountain is 28 ∘ . from a point 1000 feet closer to the mountain along the plain, they find that the angle of elevation is 30 ∘ .

Resistance can be calculated by Ohm's law
As per ohm's law we will have
here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have
So resistance of the bulb is 22 ohm.
Answer:
The constant angular acceleration of the wheel is 12.16 rad/s²
Explanation:
Given;
initial angular distance, θ = 28
time of the motion, t = 5 s
initial angular velocity is calculated as;
final angular velocity is given as,
The constant angular acceleration is calculated as;
Therefore, the constant angular acceleration of the wheel is 12.16 rad/s²
