Answer:
The average speed is 10,082
Explanation:
Do the formula
Distance * time = speed
2840 * 3.55
= 10,082
Answer:
D force mass and distance
Answer:
21870.3156 N
Explanation:
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 1.6 m/s²
Equation of motion
The acceleration of the craft should be 1.02234 m/s²
Weight of the craft
Thrust
The thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface is 21870.3156 N
A generator is a tool that is used in generating electriity. It converts mechanical energy into electrical energy in order to be used in an external circuit. The motors used for the conversion of energy contains a wire coil that is in a magnetic field. This wire coil is being used as a motor or as a generator. Using it as a generator, the wire coil should be spun results to inducing a current in the coil. When a wire coil is being spun in magnetic field, an AC electricity at constant rate is being produced which is then used by an external circuit. Generators are especially important during times of black out and lack of electricity supply from providers.
