The bulk modulus of a substance is the ratio of a small decrease in pressure to the resulting fractional increase in volume: d p dv show that b (5/3) p, in the free electron gas model, and use your result in problem 521 (d) to estimate the bulk modulus of copper. comment: the observed value is 13.4 × 100 n/m2, but don't expect perfect agreement-after all, we're neglecting all electron- nucleus and electron electron forces! actually, it is rather surprising that this calculation comes as close as it does.

Asuppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer.

What are some important factors to consider when choosing a warm-up before your workout?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
