The distance between the charge and the source of the electric field is 2.2 m.
<h3>Relationship between potential energy and Distance:</h3>
The distance of charge from the source is directly proportional to the potential energy.
Where,
- distance
- potential energy = 75 J
- Electric field =
- charge =
Put the values in the formula,
Therefore, the distance between the charge and the source of the electric field is 2.2 m.

Answer:
She is measuring her speed
Explanation:
Speed is defined as the ratio between the distance covered divided by the time taken to cover that distance:
where
d is the distance covered
t is the time taken
Since Mary is measuring how far she can run in a given period of time, she is measuring the distance she can travel (d) in a given time (t), so she is measuring her speed.
I think it was either Robert Hook or Anton Van Leevwen Hoek
Answer:
The heavier one will have twice the kinetic energy of the lighter one.
Explanation:
For the objects of mass m and 2 m , kinetic energy is
0.5 m v² and 0.5 (2 m) v² respectively. So kinetic energy of the mass 2 m is Twice that of the object of mass m, since their final velocities are equal.
When an object is dropped from the top of a building ( or from some height), its acceleration is equal to the acceleration due to gravity and has a zero initial velocity. On reaching the ground, the final velocity attained by the object depends only on the gravity and the height of fall, as given by the equation v = √2 g h.
So final velocity is independent of the mass of the object. But kinetic energy is 0.5 m v² , which shows that it depends on the mass of the object and square of the velocity.
Answer:
For macroscopic objects, we use units such as grams and kilograms to state their masses, but. There will not be much error if you estimate the mass of an atom by simply. to what we did for our hypothetical example, but the percentages are different: Add two atomic masses of carbon and six atomic masses of hydrogen:
Explanation:
