The work she on the box will be 40 J. Here the displacement due to the force is height.
<h2 /><h3>What is work done?</h3>
Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
Given data;
Force,F = 80 N
height, h = 0.5 m
Work,W = ? J
Here the displacement is height;
W = F × d
W = F × h
W = 80 N × 0.5 m
W = 40 Nm
W=40 J
Hence work she on the box will be 40 J.

B and D
Because these two points are below equator on sun is shining directly above equator which is experiencing summer
It is the speed with direction. (Ex. The car is going 4 mph south)
<h3 />
<h2 /><h2 /><h2>Acceleration : </h2>
Acceleration is a vector quantity that is defined as ❝ rate of change in velocity ❞
And as per the question, the plane can go from 0 miles to 100 miles/hour in 10 seconds that shows rate of change in its velocity. that is :
from 0 miles/hour to 100 miles/hour. hence Acceleration is the quantity being described about the new plane.
[ v = final velocity, u = initial velocity, t = time ]
So, the Acceleration of the new plane is 10 miles/hour²
