The expression like a ton of bricks means “a crushing weight.” Would being hit by an actual ton of bricks hurt if it happened on the moon?(1 point)
Responses
No, it would not hurt because the bricks would have more weight.
No, it would not hurt because the bricks would have more weight.
Yes, it would hurt because the bricks would still have more weight.
Yes, it would hurt because the bricks would still have more weight.
No, it would not hurt because the bricks would have little mass.
No, it would not hurt because the bricks would have little mass.
Yes, it would hurt because the bricks would still have the same mass.

What happens to the density of a material if you have a larger piece of it?(1 point)
Responses
The density will remain the same because mass and volume will remain the same.
The density will remain the same because mass and volume will remain the same.
The density will remain the same because mass and volume will both increase in the same way.
The density will remain the same because mass and volume will both increase in the same way.
The density will be greater because the mass increases but the volume remains the same.
The density will be greater because the mass increases but the volume remains the same.
The density will be smaller because the mass remains the same as the volume increases.
