Answer:
Explanation:
When two conducting spheres come in contact, their charges will become the mean of their charges. This takes place by the transfer of charges from the greater charged sphere to the lesser charged one.
Then :
⇒ F + G / 2
⇒ -14 + 20 / 2
⇒ 6/2
⇒ 3C
∴ Hence, both sphere F and sphere G will have a charge of +3 C.
It will take 2.77..... seconds
Answer:
Trish
Explanation:
the work done by each girl in throwing the ball is equal to the kinetic energy acquired by the ball. The ball thrown by Jamie has for sure more kinetic energy than the ball thrown by Trish, since it travels for a longer distance (25 m against 15 m), therefore this means that Jamie did more work than Trish in throwing the ball.
Answer:
a) 5 m from the finish line
b) 4875 s
Explanation:
distance = 1 km
tortoise speed = 0.2 m/s
speed of hare = 8 m/s
time take by hare t reach 0.8 km =
time taken by tortoise to travel 1 km =
time taken by the hare to travel 0.2 km =
time taken by the tortoise to travel 0.2 km =
distance traveled by tortoise in 25 second = 25 × 0.2 = 5 m
a) when tortoise is 5 m from the finish line then hare will resume the race.
b) the hare will be stationary for = 5000 - 125 = 4875 s
I would say the answer is Pangaea. I got this answer but google searching "all land" means what... and the 3rd or 4th one down it says Answers.com
But i worn you answers.com is a very slow sight...
Hope it helps
