The only thing you need to know in order to solve this task is that <span>plank length (which is force x), should equal the increase in potential energy, so what we have now : (mass)* g * (height).
It has to look like that: </span>
<span>F * 3.0 = 150 x 9.81 x 1.20
Then solve for F, the result should be in newtones = 588N
Do hope it makes sense.</span>
Answer:
No
Explanation:
Not all metals stick to magnets. Like aluminum. if you were to stick a magnet on to an aluminum it would fall off.
Gravitational force between two masses is given by formula
here we know that
now from the above equation we will have
so above is the gravitational force between car and the person
Mass is an intrinsic property of the rock. The mass doesn't care where it is, and it makes no difference where the rock happens to be at the moment ... its mass doesn't change.
17kg of mass is 17kg . If it's 17kg on the moon, it's <em>17kg</em> on Earth.
