Answer:
An increase in angular speed due to conservation of energy priciple.
Explanation:
This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.
It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.
Acceleration due to gravity is about 9.8 m/s²
So after every second, the speed increase by 9.8 m/s
After 1 second, the object would fall at a speed of 9.8 m/s
After 2 seconds the object would fall at a speed of 19.6 m/s
So after 4 seconds, the object is going to be at a speed of:
9.8 x 4 = 39.2 m/s

39.2 m/s
Answer:
microscopic light or Nano technology
Answer:
Magnetic force, F = 38.95 N
Explanation:
Given that,
Length of the conductor, L = 3.88 m
Magnetic field, B = 2 T
Current flowing in the conductor, I = 5.02 A
The magnetic field perpendicular to the plane of the semicircle. The angle between the magnetic field and the plane is 90 degrees. The expression for the magnetic force is given by:
F = 38.95 N
So, the magnitude of the total force acting on the conductor in the magnetic field is 38.95 N. Hence, this is the required solution.
