In a musical instrument, sound waves build up by constructive interference until they are loud enough to hear. this concept is known as

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

vapour or gas assuming atmospheriv pressure

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.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
