A50 kg skater twirls at 0.77 rev/s with her arms extended. she then brings her arms in and twirls at 1.03 rev/s. the skater's mass moment of inertia can be determined by approximating her to be a uniform cylinder with radius 13 cm when her arms are in.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
