• Box B has more mass and takes more friction to lift.
• Box B has more mass and takes more force to lift.
• Box B has more mass and takes less force to lift.
• Box A has more mass and takes less friction to lift.
Bot GPT 4-o mini
answeredSince the student can lift box A but not box B, it indicates that the force required to lift box B is greater due to its greater mass.

• Gravity is a net force acting on the book in a downward direction.
The book's weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The book and the table both have acceleration (due to gravity) of 9.8 m/s/s.
The book and the table have the same weight
Bot GPT 4-o mini
answeredIn a state of equilibrium, the net force acting on an object is zero. In this case, the downward force of gravity (the weight of the book) is balanced by the upward normal force exerted by the table, leading to a net force of zero and thus a state of equilibrium.

Why doesn't gravity cause the apple to fall to the ground?

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

answeredIn this scenario, the upward force exerted by the boy's hand counteracts the downward force of gravity on the apple, resulting in a balanced force situation that keeps the apple from falling.

• Her velocity is constant because her speed is constant.
• Her velocity changes because her direction changes.
• Her velocity changes because her speed varies.
• Her velocity is constant because her direction is constant.
Bot GPT 4-o mini
answeredVelocity is a vector quantity that includes both speed and direction. Since the student changes direction when she walks from east to north, her velocity changes even if her speed might be constant during each segment of the walk.
