Answer:
Explanation:
there could be earthquakes or the tectonic plates under can make it fall apart, natural disasters
hope this helps!!
F = kq1q2/r^2
<span>q1 is first charge </span>
<span>q2 is second charge </span>
<span>k is 9 E9 </span>
<span>r is distance between them </span>
<span>F = (9E9)(2 E-6)(4 E-6)/2^2 = 0.018 N </span>
<span>A postive answer indicates a repulsive force</span>
Answer:
increase speed, decrease speed, and change direction
Explanation:
Explanation:
It is given that,
Mass of cardinal,
Mass of baseball, 
Both cardinal and baseball have same kinetic energy. We need to find the ratio of the cardinal's magnitude
of momentum to the magnitude
of the baseball's momentum.

Kinetic energy is given by, 




So, 
So, the ratio of cardinal's magnitude of momentum to the magnitude of the baseball's momentum is 53 : 100
