the density of liquid water is 1.0 g/cm”, the density of rock is 2.7 g/cm', the density of iron is 7.9 g/cm². Add this information to your graph. 9. Are the densities of the planets roughly proportional to their diameters? Use evidence to support your claim.​

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
