Answer: Machanical advantage of the machine is 1.86
Explanation: Machanical advantage of a machine is the ratio of the Force to overcome which is the load in this case 24kg * 10= 240N to the force exerted(Effort) to overcome the load in this case 129N.
So, we have
MA = load/effort
= 240N/129N
= 1.86.
The different reflections of light through two separate mediums causes the bending of wave fronts associated with light rays. The reflection and refraction is caused by the medium associated with its light rays.
It would connect the Earth of the device to Live, causing the metal casing of the device to become Live, touching it would cause a serious electrical shock.
Answer:
d)no unit
