A change that would most improve his results would be; D) Connecting the galvanometer to the coil
Under the Neutrality Act, all of the following conditions were agreed to except America would provide aid to any nation attacked by Axis Powers. The correct option in regards to all the options given in the question is option"a". During the 1930's the United Nations Congress passed the Neutrality Act. It was passed keeping in mind the turmoil Europe and Asia were passing through during that time. Eventually the turmoil led to the starting of World War II. The Acts were modified several times and ultimately withdrawn when the United States ships were attacked by German submarines.

Complete Question:
A 10 kg block is pulled across a horizontal surface by a rope that is oriented at 60° relative to the horizontal surface.
The tension in the rope is constant and equal to 40 N as the block is pulled. What is the instantaneous power (in W) supplied by the tension in the rope if the block when the block is 5 m away from its starting point? The coefficient of kinetic friction between the block and the floor is 0.2 and you may assume that the block starting at rest.
Answer:
Power = 54.07 W
Explanation:
Mass of the block = 10 kg
Angle made with the horizontal, θ = 60°
Distance covered, d = 5 m
Tension in the rope, T = 40 N
Coefficient of kinetic friction, 
Let the Normal reaction = N
The weight of the block acting downwards = mg
The vertical resolution of the 40 N force, 
Power, 
<em>12,25 km/h</em>
<em>≈ 3,4 m/s </em>
<em>v = d/t</em>
<em>= 12250m/h</em>
<em>= 12,25km/h</em>
<em>or</em>
<em>v = d/t</em>
<em>= 12250m/h</em>
<em>1h = 60m×60s = 3600s</em>
<em>= 12250m/3600s</em>
<em>≈ 3,4 m/s </em>
