Answer:
E= 2.158× 10*5N/C
Explanation:
K= 8.99×10*9, q= 6×10*-6C, d= 0.5m
E= kq/d*2
E= (8.99×10*9× 6×10*-6)/0.5*2
E= 215760
E= 2.158 ×10*5N/C
Answer:
magnitude of v = 2.5 m/s, and in the same direction as the initial velocity of the 5 kg ball.
Explanation:
We use conservation of linear momentum in an elastic collision to solve for the unknown velocity v:
Pi = Pf
5 kg * 5 m/s + 10 kg * 0 m/s = 5 kg * 0 m/s + 10 kg * v
25 kg m/s = 10 kg * v
v = 25/10 m/s
v = 2.5 m/s
and in the same direction as the initial velocity of the 5 kg ball.
There's a few differences. In a physical change the actual substance doesn't change, where in a chemical change with chemical reaction, a new substance is formed. Physical change can be reversed, and chemical change can't.
We dissect frogs
Worms are to small for a scalpel and nothing to look at rlly
Starfish are illegal to dissect
Pigs are to big for a classroom and they can’t be cryogenics frozen to be dissected
