B student 2 because you add
Answer:
Explanation:The work done is twice as great for block B because it is moved twice the ... Equal forces are used to move blocks A and B across the floor. ... Does the normal force of the floor pushing upward on the block do any work? ... Suppose that the mass is halfway between one of the extreme points of its motion and the center point.
The force of gravity is less between to objects when the product
of their masses is smaller, or when they are farther apart.
The answer is D. The current in the battery and in each resistor is the same.
If we have two or more components in series, the current that flows through each of them is the same.
In this case, the battery generates the current, and since there must be conservation of electric charge, no current can be lost through the resistors.
