Answer:
A) Wn = 90J
B) W1 = 100J
W2 = 10J
Explanation:
A) The net work done on the box is calculated by using the following formula:
(1)
F1 = 100N
F2 = 10N
d: distance on which the box is moved = 1m
You replace the values of the parameters in the equation (1):

The net work on the box is 90J
B) The total work done by each force is:

The first box does a work of 100J and the second force does a force of 10J
Because there is no oxygen in space and we need oxygen to function so we need the suit to incapsulate us in oxygen so we can respire and so can our skin
