A pendulum with a period of ones on earth where the acceleration
Answer:
false
Explanation:
Even small environmental changes have large effects because small things become bigger
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
Answer:
chris gets 960 and molly gets 1440
Explanation:
add the ratio up and divide
2+3=5
2400/5=480
480x2=960
480x3=1440
960+1440= 2400
Answer:
Use the principle of momentum
Initial momentum = final momentum
Momentum formula = Mass * Velocity
