Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150mw by the radio active decay of fission products. this heat transfer causes a rapid increase in temperature if the cooling system fails. (1 watt = 1 joule or 1w = 1j/s and 1mw = 1megawatt)calculate the rate of temperature increase in degrees celsius per second (°c/s) if the mass of the reactor core is 1.60×105kg and it has an average specific heat of 0.3349 kj/kg°c.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

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)
