A boy holds out a apple in his right hand.
Why doesn’t gravity cause the apple to fall to the ground?

The force of his hand pushes up on the apple with equal magnitude to the force of gravity, which pulls down on the apple. The two forces are unbalanced, so the apple doesn't fall.

The force of his hand pushes up on the apple with greater magnitude than the force of gravity, which pulls down on the apple. The two forces are unbalanced, so the apple doesn't fall.

The correct response is: The force of his hand pushes up on the apple with equal magnitude to the force of gravity, which pulls down on the apple. The two forces are balanced, so the apple doesn't fall.

Gravity is a force that pulls objects toward the center of the Earth. When the boy holds the apple in his hand, gravity is still acting on it, but it is balanced by the force of his hand pushing up on the apple. This creates a condition where the forces are equal in magnitude but opposite in direction, resulting in a state of equilibrium. As a result, the apple remains stationary and doesn't fall to the ground.
The correct answer is: The force of his hand pushes up on the apple with equal magnitude to the force of gravity, which pulls down on the apple. The two forces are balanced, so the apple doesn't fall.
are you sure??
Yes, I am sure. When the boy holds the apple in his hand, the force of gravity is pulling the apple downward towards the ground. However, the boy's hand also exerts an upward force on the apple. As long as the magnitude of the upward force is equal to the magnitude of the downward force of gravity, the two forces cancel each other out and result in a balanced situation. This is why the apple doesn't fall.
The spacecraft shown below weighs 6.1 million pounds. The rocket produces 7.5 million pounds of thrust.
When the spacecraft falls back to earth, a parachute helps it fall safely. Explain the forces acting during this landing.

The correct response is: The parachute’s upward force resists gravity’s downward force.
When the spacecraft falls back to Earth, gravity pulls it downward towards the ground. The parachute is deployed to create drag and generate an upward force. This upward force of the parachute opposes the downward force of gravity, slowing down the descent of the spacecraft and allowing it to land safely.
