Answer:
<em>The person needs to apply 25 N to balance the seesaw</em>
Explanation:
<u>Moment</u>
The moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.
The moment M of a force F located at a distance x from the axis of rotation is calculated as follows:
M = F.x
The image shows a moment of M=100 N.m is needed to be applied to balance the seesaw. It can also be noted that the distance to the pivot is x=4 m
To calculate the force needed to balance the seesaw, we solve for F:


F = 25 N
The person needs to apply 25 N to balance the seesaw
Very high-energy objects and events spit out very high-energy photons, so the instrument you need in order to detect them is the X-ray telescope. <em>(C) </em>
Inconveniently, X-ray telescopes only work when they're up in orbit, because X-rays get seriously soaked up in Earth's atmosphere, and most of them never make it down to the surface ... (lucky for us !) .
The atoms furthest from the nucleus
We don't know Carter, and we don't know where he is or what
he's doing, so I'm taking a big chance speculating on an answer.
I'm going to say that if Carter is pretty much just standing there,
or, let's say, lying on the ground taking a nap, then the force of
the ground acting on him is precisely exactly equal to his weight.
Answer:

Explanation:
Since,
<h3><u>1 kWh = 1 unit</u></h3>
So,
1.6 kWh = 1.6 units
If,
<h3>1 unit = 9p</h3>
1.6 units = 9p × 1.6
1.6 units = 14.4p
