Answer:

It obeys Newton's third law of motion.

Explanation:

The experiment obeys Newton's third law of motion because when the air in the balloon is released, the air moves in the downward direction which is an action of the balloon so in the reaction, the balloon moves in upward direction   so both action and reaction forces are equal in magnitude but moves in opposite direction which obeys Newton's third law of motion.

A student was trying to find the relationship between mass and force. He placed four different masses on a table and pulled them
Gwar [14]

Answer:

B. There is a direct proportion between the mass and force listed in the table.

Explanation:

From the table, the values of force increases with increase in the value of mass.

if 5kg=25 N

Finding the contant of proportionality k;

k=25/5=5

thus M=k(F)...........where M is mass in kg and F is force in newton, then

M=5F

This show that for every value of mass, we get the value of Force if we multiply by a contant k=5

This means there is a direct proportionality relation between mass and force in the table.
