We will first analyze the experiment with the lead shot. compute the change in temperature for the lead shot, the water, and the calorimeter cup. compute the heat flow, q, for the water and the calorimeter cup. now, use eq. 2 to compute an experimental value for the specific heat capacity of the lead shot. perform the same analysis as above to determine an experimental value for the specific heat capacity of the aluminum shot.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
