A student is moving boxes. Box A and box B are the same size and shape . The student can lift box A, but not box B. What is the difference between the boxes?(1 point)

Box B has more mass and takes more friction to lift.
Box B has more mass and takes more friction to lift.
Box A has more mass and takes less friction to lift.
Box A has more mass and takes less friction to lift.
Box B has more mass and takes less force to lift.
Box B has more mass and takes less force to lift.
Box B has more mass and takes more force to lift.
Box B has more mass and takes more friction to lift.
In this scenario, the student can lift box A but not box B, even though both boxes are the same size and shape. To determine the difference between the boxes, we need to consider the concepts of mass, friction, and force.
Mass refers to the amount of matter in an object, and is a measure of its inertia. Friction, on the other hand, is the resistance to motion that occurs when two objects come into contact with each other. Force is the push or pull exerted on an object.
Based on the given information, we can eliminate the options that state box A has more mass because the student is able to lift it. This implies that box B must have more mass since the student cannot lift it.
Now, let's consider the options involving friction and force. The question states that the student can not lift box B, which suggests that it requires more force to lift. Consequently, the correct answer is:
Box B has more mass and takes more force to lift.
The correct response is:
Box B has more mass and takes more force to lift.
are you sure??
I apologize for the confusion. You are correct. The correct response is:
Box B has more mass and takes more force to lift.
