How does the magnitude of the normal force compare to the weight of the box?
The magnitude of the normal force is equal to the weight of the box when the box is at rest on a flat surface.
How does the gravitational attraction of the earth to the apple compare?
The gravitational attraction of the Earth to the apple is equal in magnitude to the gravitational attraction of the apple to the Earth. This is in accordance with Newton's Third Law of Motion, stating that for every action, there is an equal and opposite reaction.
What is the magnitude of the gravitational force exerted by an apple on the Earth if the apple is 2 N?
The magnitude of the gravitational force exerted by the apple on the Earth is equal to the force exerted by the Earth on the apple, which is 2 N in this case (according to Newton's third law of motion). This force is responsible for the apple's weight and is equal in magnitude but opposite in direction for both bodies.
What is the reaction force to the gravitational force acting on your body as you sit in your desk chair?
The reaction force to the gravitational force acting on your body as you sit in your desk chair is the normal force exerted by the chair on your body. It is equal in magnitude and opposite in direction to the force of gravity, balancing the forces and keeping you in equilibrium.
What must be the charge on each of two 100 kg spherical masses in order for the electrical force to be equal to the gravitational force?
The electrical force between the two masses is equal to the gravitational force when the magnitude of the electrical force, given by Coulomb's law, is equal to the magnitude of the gravitational force, given by Newton's law of universal gravitation. By setting these equal and solving for charge, you can find that the charges on the two masses must be around 1.45 x 10^17 C each.
What is the magnitude of the normal force on the car when it is at the top of the circle?
At the top of the circle, the magnitude of the normal force on the car is equal to the sum of the car's weight and the centripetal force required to keep it moving in a circular path.
An apple falls because of the gravitational attraction to earth. How does the gravitational attraction of the earth to the apple compare?
The gravitational attraction of the Earth to the apple is equal in magnitude to the gravitational attraction of the apple to the Earth. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
What force is acting is acting on the book resting on a table?
The force acting on the book when it is resting on a table is the gravitational force pulling the book downwards. This force is equal in magnitude and opposite in direction to the normal force exerted by the table on the book, keeping it in equilibrium.
How does the normal force on you compare to your weight when you stand on a floor?
When you stand on a floor, the normal force acting on you is equal in magnitude but opposite in direction to your weight.
Two spheres have equal densities and are subject only to their mutual gravitational attraction. Which quantity must have the same magnitude for both spheres?
You may be looking at a list of multiple choices. I don't know, and I can't see it. The force acting on each sphere and attracting it in the direction of the other sphere is the same.
The mesurement of the force of gravity on an object is the objects?
The magnitude of the equal gravitational forces in both directions between the earth and any object on it is the object's "weight".
What is the magnitude of the tension in the string when the ball is at the bottom of the circle?
The magnitude of the tension in the string at the bottom of the circle is equal to the sum of the gravitational force acting on the ball and the centripetal force required to keep the ball moving in a circular path.
