In the given question, we already know
Work done = 150 joules
Force = 120 Newton
Now we know from the study of physics that
Distance (D) = Work done / Force
(a) To find the height upto which the backpack has been lifted,
D = Work done / Force
= 150 / 120
= 15 / 12
= 5 / 4
= 1.25
So the backpack was lifted to a height of 1.25 metres.
(b) Now we have the find the weight of the backpack in pounds
We know that 1 pound = 4.448 Newton
So if
4.448 Newton = 1 pound
Then
120 Newton = (120 / 4.448) pounds
= 26.978 pounds
So the backpack weighed 26.98 pounds.
Answer:
Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation.
Explanation:
A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
Answer:
the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.

Explanation:
I haven't worked on Part-A, and I don't happen to know the magnitude of the gravitational force that the Sun exerts on the Earth.
But whatever it is, it's exactly, precisely, identical, the same, and equal to the magnitude of the gravitational force that the Earth exerts on the Sun.
I think that's the THIRD choice here, but I'm not sure of that either.
A this refers to the make up of the soil
