Answer:
it loses engry it follows difernt paths
Explanation:
All it does is lets him pull in a more convenient direction to raise the load. It has no effect on the required force.
Answer:
option (E) 1,000,000 J
Explanation:
Given:
Mass of the suspension cable, m = 1,000 kg
Distance, h = 100 m
Now,
from the work energy theorem
Work done by the gravity = Work done by brake
or
mgh = Work done by brake
where, g is the acceleration due to the gravity = 10 m/s²
or
Work done by brake = 1000 × 10 × 100
or
Work done by brake = 1,000,000 J
this work done is the release of heat in the brakes
Hence, the correct answer is option (E) 1,000,000 J
Answer:
kinematics is a subfield of physics developed in classical mechanics that describes the motion of point , bodies (objects) , and systems of bodies (group of objects ) without considering the forces that cause them to move
Given :
Current, I = 3.75 A .
Magnetic Field, 
To Find :
The distance from the wire.
Solution :
We know,
Hence, this is the required solution.
