Answer:
-20N
Explanation:
The racquet ball will bounce back with the same force.
This is in compliance with newton's third law of motion:
"action and reaction are equal but opposite"
If the ball hits the wall with an action force of 20N, the reaction force will be -20N.
The negative indicates an oppositely directed force.
Answer:
the rock will sink. this is because it is more dense than water
Answer:
True
Explanation:
Because AxB=lAllBlsin(x)
and x is the angle between them
so, the angle is 180° and sin180 is zero.
