Find the speed of a satellite in a circular orbit around the earth with a radius 4.03 times the mean radius of the earth. (radius of earth = 6.37×103 km, mass of earth = 5.98×1024 kg, g = 6.67×10-11 nm2/kg2.)

The softest and hardest minerals are: softest hardest

What’s #16 asking and how do i solve it?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
