I really need this answer quick. I would really appreciate it if anyone could answer with an explanation. Thank you! 6. The temperature of a sample of iron with a mass of 10.0 g changed from 50.4°C to a final temperature of 25.0°C when dropped in 90 grams of water, initially at 23.5 °C. What is the specific heat of iron?

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
