The solid block shown here has a mass of 146 grams. What is the block’s density?

1 answer:

4 0

Had you included the picture, we would also know the height. Without that, we can't calculate the volume, and without the volume, we can't calculate the density.

A hammer is used to hit a nail into a board. Which statement is correct about the forces at play between the nail and the hammer

Montano1993 [528]

Answer:

reviewing the final statements, the correct one is the quarter

The nail exerts an equal force on the hammer in the opposite direction.

Explanation:

This is an action-reaction problem or Newton's third law, which states that forces in naturals occur in pairs.

This is the foregoing, the hammer exerts a force on the nail of magnitude F and it will direct downwards, if we call this action and the nail exerts a force on the hammer of equal magnitude but opposite direction bone directed upwards, each force is applied in one of the bodies.

The difference in result that each force is that the force between the nail exerts a very high pressure (relation between the force between the nail area), instead the area of the hammer is much greater, therefore the pressure is small.

When reviewing the final statements, the correct one is the quarter

The nail exerts an equal force on the hammer in the opposite direction.
