Answer
given,
mass of the crate = 53 Kg
force applied by the worker = 180 N
Angle made with the horizontal = 35°
crate moves = 2.9 m
a) The work done equals the force in the direction of the displacement, times the displacement
W = F_x ×d
W = 180 cos 35° × 2.9
W = 427.6 J
b) A force that is perpendicular to the direction of the displacement does not do any work so work done by gravitational force is zero
c) Similarly for the normal force the work done will be zero.
d) Total work done by the crate is equal to 427.6 J
Answer:
Quick action was in this as a thought of he knew he could die from this
The correct answer would be c
Answer:
D.
Explanation:
Force and distance are inversely related, so a greater distance results in a weaker force.
Hello!
The number of field lines in a given area does NOT depend on how far the region is away from a source charge.
The number of field lines depends SOLELY on the strength of the charge of the source. Therefore, the amount of field lines encompassed by a shell of radius 'R' and radius '2R' is the same.
The ONLY thing that changes as a result of increased distance is the spacing between the electric field lines which signifies the decreasing electric field strength as you move farther away from the source charge.
