Answer:
(a) 81.54 N
(b) 570.75 J
(c) - 570.75 J
(d) 0 J, 0 J
(e) 0 J
Explanation:
mass of crate, m = 32 kg
distance, s = 7 m
coefficient of friction = 0.26
(a) As it is moving with constant velocity so the force applied is equal to the friction force.
F = 0.26 x m x g = 0.26 x 32 x 9.8 = 81.54 N
(b) The work done on the crate
W = F x s = 81.54 x 7 = 570.75 J
(c) Work done by the friction
W' = - W = - 570.75 J
(d) Work done by the normal force
W'' = m g cos 90 = 0 J
Work done by the gravity
Wg = m g cos 90 = 0 J
(e) The total work done is
Wnet = W + W' + W'' + Wg = 570.75 - 570.75 + 0 = 0 J
We have that Zero signifies a perfect circle shape and 1 shows it maximum out of order shape.
From the question we are told
What does it mean when the orbital eccentricity of a planet is close to 1
Generally
Eccentricity
This in its simplest definition means to be eccentric which means to be a bit out of order or for the given subject at hand means to be a bit out of shape
Naturally the Eccentricity that an object possess is defined by two number 0(zero) to 1(one)
Where
Zero signifies a perfect circle shape and 1 shows it maximum out of order shape

The percent difference between two numbers and is given by
The absolute value is there because we only care about the absolute percent difference, and not taking into account whether we go from to or vice versa. If we remove them, we have two possible interpretations of percent difference.
For example, the (absolute) percent difference between 3 and 6 is
In other words, we add 100% of 3 to 3 to end up with 6. This is the same as the percent difference going from 3 to 6. On the other hand, the percent difference going from 6 to 3 is
which is to say, we take away 50% of 6 away from 6 to end up with 3.
"Make comparisons to object measurements" tells us that the differences should be computed relative to "measurements for object". In other words, take from the left column and from the right column.
