The magnitude of the downward force of section A of a massless rope is zero because a massless rope does not exert any force due to gravity. However, it can transmit forces applied to it from other sources.

How big is the upward force compared to the downward force?

Down ward force is greater than upward force because everything on earth, obeys the laws of gravity, and for a rocket to take off from earth it needs more energy in other to fight the earths gravitational force but despite fighting the gravitational force it still doesnt take off with a full speed, But for a body of mass to fall from the atmosphere its falls with a great speed due to the force of the earths gravity.


If an objects weight is less than the boyant force will sink or float?

If an object's weight is less than the buoyant force acting on it, the object will float. This is because the buoyant force acting upward is greater than the force of gravity pulling the object downward.


When a body moves with constant velocity what is the magnitude of net force is the magnitude of force applied to keep the body moving equal to less than or more than frictional force explain?

When a body moves with constant velocity, the net force acting on it is zero as there is no acceleration. The magnitude of the force applied to keep the body moving is equal to the frictional force opposing its motion. This ensures that the forces are balanced, resulting in a constant velocity without any acceleration.


Why does cardboard float?

Cardboard floats because it is less dense than water. When placed in water, the upward buoyant force is greater than the downward force of gravity, causing the cardboard to float.


Does Earth exert a upward or downward force on your body?

Earth exerts a downward (towards the ground or Earth) force on your body. At the same time, your body exerts an upward (towards your body) force on the Earth. Your body is the one that seems to move, however, because the mass of your body is so much less than the mass of the Earth.

What is the effect on the resultant of increasing the angle between the two forces?

The direction will change; the magnitude of the resultant force will be less.


What force pushes upward on the continental crust What force pushes downward?

The force pushing upward on the continental crust is isostatic rebound, caused by the buoyancy of the less dense continental crust floating on the denser mantle. The downward force is from the weight of the overlying rock and sediments, as well as tectonic forces like subduction or compression.

What what happened to the magnitude of gravitational force between the Sun and Earth if earth was place in Pluto's orbit?

it would be less than what it was before


Why is the magnitude of buoyancy force on a metal cylinder that is fully immerse in less dense fluid is lesser than if it is fully immerse in water?

because things that are fully sick sink :P this happens because the magnitude of buoyancy is dependent on the volume of the object and the density of the liquid. Since the liquid is less dense, the buoyant force is reduced.


Why could you not slide very quickly on a slide cover with sandpaper?

Sandpaper is designed to be a high-friction material. High friction on a slide means less downward force, which means less acceleration and less velocity.

Why fish weigh less in water than in air?

Fish weigh less in water because of buoyancy, which is the upward force exerted by a fluid that counteracts the weight of the object immersed in it. The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.


What magnitude is not possible when a vector of a magnitude of 3 is added to a vector of a magnitude of 4?

It is not possible to obtain a vector with a magnitude of 7 when adding vectors of magnitude 3 and 4. The resultant magnitude will be between 1 and 7, as the triangle inequality states that the magnitude of the sum of two vectors is less than or equal to the sum of their magnitudes.
