The electric force exerted by an electric field of intensity E on a charge q is equal to the product between E and q, so:
Answer:
Velocity
Explanation:
The slope of a position-time graph gives velocity of a moving object.
Answer:
they are found in a nucleus
Explanation:
Answer:
An atomic nucleus consists of protons and neutrons, collectively called nucleons. Although protons repel each other, the nucleus is held tightly together by a short-range, but very strong, force called the strong nuclear force. A nucleus has less mass than the total mass of its constituent nucleons.
Explanation:
The chair is exerting a force of 800N.
Force is a quantity that is used to describe the interaction between two objects. Forces can cause objects to accelerate, decelerate, or change direction. In other words, forces can cause objects to move or change the way they are moving. The weight of an object is a measure of the force of gravity on that object and is calculated by multiplying the object's mass by the acceleration due to gravity.
In the given case, It would need a force equal to his weight (800 N) pressing in the opposite direction for the man to be able to rise up in the chair. Therefore, the 800 N force would be pushed upwards if he were to press down by standing on it.
