A diver goes into a somersault during a dive by tucking her limbs. If her rotational kinetic energy is 100 J and her moment of inertia in the tuck is 9.0 kg·m^2, what is her rotational rate during the somersault?
Rotational Rate During a Somersault Dive To find the rotational rate \( \omega \) during the somersault, we use the formula for rotational kinetic energy: \[ K = \frac{1}{2} I \omega^2 \] Where:...

A student weighs 2.046 g of Cu into a 250 mL beaker at the beginning of the experiment. At the end of the experiment 1.374 g Cu is recovered. Calculate the percent loss of Cu.
w = (2.046 - 1.374)/2.046*100% = 32.84%

Calculate the volume, in cubic centimeters, occupied by 0.022 mmole lead (density = 11.3 g/cc)
0.022 mmole of Pb (molar mass is 207.20):207.20 x 0.022 / 1000 = 0.0045584 g d = m/VV = m/dV = 0.0045584 g / 11.3 cc = 4.0x10-4 cc (cubic...
