Answer:
B,C
Explanation:
In the law of magnetism, like poles repel and unlike poles attract. The north and South Pole attracts which makes B correct. The north and north or south and south poles repel.
In a compass ,the north end of a magnet is attracted to the south magnetic pole which is in close proximity to the geographic South Pole. This makes
Option c correct.
B. The ball will slow down.
external force of rolling friction is there
I don't know how good you are at sketching ... I'm terrible.
But you can put the point across in a dramatic way if you
can sketch a bowling ball and a basketball ... you'll need
to clearly identify them with the markings you sketch on
each ball.
They're the same shape and nearly the same size, but
there's a huge difference in their densities.
Answer:
(a) Angular speed will be 0.2512 rad/sec
(b) Radius will be 213.375 m
Explanation:
We have given time to complete 1 lap = 25 sec
We know that 1 lap = 
radian
(a) So angular speed 
(B) Tangential velocity is given as v = 53.6 m/sec
We know that tangential velocity is given by
So radius 
-3.33 m/s^2
The soccer player decelerates from 10 m/s
to 0 m/s. Because he decelerates the acceleration will be a negative
value. Since he takes 3 seconds to decelerate, divide his original
velocity by 3
One major point to be careful of is to keep p
