Not sure I understand can you explain more
Answer:
(a)
4) The magnitude of buoyancy force is equal to that of ball's weight
(b) The magnitude of buoyancy force is larger than that of ball's weight. The tension on second ball is 158 newtons
(c) The magnitude of buoyancy force is larger than that of ball's weight. The tension on third ball is 218 newtons.
Explanation:
Newton's third law of motion states that forces always occurs in pairs. For every reaction there is an equal an opposite reaction. For Ball 1 the magnitude of buoyancy force is equal to that of ball's weight. Buoyancy force works against the gravity. Ball 2 and ball 3 have same buoyancy force. The buoyancy force for ball 2 and ball 3 is larger than that of ball's weight.
Tension = Wb - fb
Tension for Ball 2 = 1000 - 842 = 158 newtons
Tension for Ball 3 = 1000 - 1218 = -218 newtons
<u>Answer:</u>
Cheryl, Heather and Keaton all are correct.
<u>Explanation:</u>
Everything around you is made of matter and matter is anything that has mass and occupies space or in other words, anything which has volume is called matter.
Here, in the given example, Cheryl, Heather and Keaton all are correct because the mug, the hot chocolate which is inside the mug and the steam coming out of it, all have mass. Therefore, all are correct except for Mikayla.
