Assuming the planet can be treated as a solid sphere,
(9.74 x 10^37 kg-m²) = (2/5)(5.98 x 10^24 kg)R²
R = 6.38 x 10^6 m
Answer:
A water fall?
Explanation:
It's an example I took in my science class
The equation for determining the kinetic energy of the system is,
KE = 0.5mv²
where m is the mass, v is velocity and KE is the kinetic energy. When both objects have the same mass, and velocity but different direction, they will have the same kinetic energy.
This is because the exponent in the velocity is squared cancelling out the effect of the sign appearing before the number.
So for an incident rag from vacuum to a medium with n=1.6, and an incident angle of 53 degrees, the the angle of refraction will be .
Mike enters a revolving door that is not moving. Mike should
push at the edge of the door where it is largest distance from the pivot point
in order to produce a torque with the least amount of force. Torque is equal to
t = force x distance.
