The compass of an airplane indicates that it is headed due north, and its airspeed indicator shows that it is moving through the air at 400 km/h. there is a wind of 300 km/h from west to east. (a) in what direction is the airplane actually heading? [note: calculate the degree measure of the angle and specify e of n or w of n] (b) expressed in hours, how long a time will it take the airplane to cover a distance of 2000 km?

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.

i think it's 35 meters

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
