Explanation:

Displacement is a <em>difference </em>between an initial value and a final value, not factoring in any changes that happen in between. For example you let an object of a certain volume sink to the bottom of a container of water, the water level will be <em>displaced</em>, or changed, by exactly the volume of that object.

<em>Example</em>: A marble with volume of 3 cm³ is dropped into a graduated cyllinder with 10 mL of water. The water level rises to the 13 mL mark, so the <em>displacement </em>of the water by the marble is exactly 3 mL.

This doesn't just apply to a change in volume: If I move a box 3 meters along an axis in the positive direction, we say its <em>displacement</em> along that axis is 3 meters. If I moved it in the negative direction the same distance, the displacement would be -3 meters.

Answer:

Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance and not an "end-point."

How do mass and distance affect gravity?
elixir [45]
A gravitational force between objects depends on two things- their masses and the distance between them. So the greater the mass and the less distance there is, the more gravitational force and is the mass is less and the distance is great the gravitational force is weak

kogti [31]

Answer:

<h2>7.21 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 2.060 × 3.5

We have the final answer as

<h3>7.21 J</h3>

Hope this helps you

A 15kg hoop with a radius of 3 m is rolling at on a level surface when it reaches a 25 degree incline. If it reaches a height of
dimulka [17.4K]

The initial velocity of the hoop is determined as 8.854 m/s.

<h3>Conservation of energy</h3>

The initial velocity of the hoop can be determined from the principle of conservation of energy.

Final potential energy = Initial kinetic energy

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

2gh = v²

√2gh = v

√(2 x 9.8 x 4) = v

8.854 m/s = v

Thus, the initial velocity of the hoop is determined as 8.854 m/s.
