Answer:
6.6 N
Explanation:
Let's take the direction of the force of 4.0 N as positive x-direction. This means that the force of 3.0 N is at 40 degrees above it. So the components of the two forces along the x- and y-directions are:


So the resultant has components

So the magnitude of the resultant is

And in order for the body to be balanced, the third force must be equal and opposite (in direction) to this force: so, the magnitude of the third force must be 6.6 N.
Answer:
it's right you did a great job
C is not mechanical weathering. It is chemical weathering.
Answer:
14.4kJ
Explanation:
Work = Force x distance
W × h = mgh
Given that,
mass m, = 59.5kg
acceleration due to gravity = 9.8m/s^2
height ,h = 16.2cm
convert to m is 0.162m
How much work = m x g x h
height is 0.162 x 152 steps
h = 24.624m
work = 59.5 x 9.8 x 24.624
= 14,358.25Joule
= 14.4kJ
