Answer:
D. You would weigh the same on both planets because their masses
and the distance to their centers of gravity are the same.
Explanation:
The above statement is true due to the fact that, the weight and masses of the individual are same in direct comparison with the distance to their center of gravity.<em> If the weight and masses are not same, then there would have been a significant difference between the two planet.</em>
Answer:
The self-inductance is
Explanation:
From the question we are told that
The number of loops is
The length of the rod is
The radius of the rod is
The self-inductance for the solenoid is mathematically represented as
Now the cross-sectional of the solenoid is mathematically evaluated as
substituting values
and is the permeability of free space with a value
substituting values into above equation
B. If the amount of animals that ate the rabbits decreased, there would be less rabbits dying, leading to over population.
Answer:
W = 0 :The work done on the wall is zero,because the wall is not moving
Explanation:
Work theory
Work is the product of a force applied to a body and the displacement of the body in the direction of this force.
W= F*d Formula (1)
W: Work (Joules) (J)
F: force applied (N)
d=displacement of the body (m)
The work is positive (W+) if the force goes in the same direction of movement.
The work is negative (W-)if the force goes in the opposite direction to the movement
Data
F= 400-N
d= 0
Problem development
We apply formula (1) to calculate the work done on the wall:
W= 400*0
W=0
When a rock is dropped from a bridge in this way, in terms of the magnitude of the acceleration and the speed of the rock as it falls, the best option is "<span>(1) Both acceleration and speed increase."</span>
