Answer:
Change in momentum will be -4.4 kgm/sec
So option (A) is correct option
Explanation:
Mass of the ball is given m = 0.10 kg
Initial velocity of ball 
And velocity after rebound 
We have to find the change in momentum
So change in momentum is equal to 
( here negative sign shows only direction )
So option (A) will be correct answer
Answer:
I think it's Experimental
Explanation:
it has atoms on it.
A build up of charges on a sock from a dryer
Answer:
9.1848 km straight east and 10.5659 km straight north
Explanation:
To find these distances, you just have to find the components of this displacement. The inclination in relation to north is 41 degrees, so to find the north component, you need to multiply 14 km by the cossine of 41 degrees, which is 0.7547.
So, the north component is 14 * 0.7547 = 10.5659 km
To find the east component, you multiply 14 by the sine of 41 degrees, which is 0.6561:
14 * 0.6561 = 9.1848 km
You would need to drive 9.1848 km straight east and then 10.5659 km straight north to arrive at the same point.
