In the winter olympics, an ice skater may lift his partner high above his head. a typical female ice skater weighs 400 n, and the male can usually lift her 1.4 m above the ice. how much work does the male ice skater exert when he lifts the female ice skater 1.4 m above the ice?

a. 560 j
b. 286 n-m
c. 560 n-m
d. 286 j

Which two objects have the greatest gravitational force acting between them

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
