A police car siren emits a frequency of 2010 Hz when stationary. Another car
hears a 1920 Hz sound when it drives
away from the stationary police car,
How fast is the second car driving?
(Speed of sound = 343 m/s)
(Unit = m/s)

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

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.

mass:

formula.

example:

given values:

mass = 0.3 kg.

the closer the planet is to the sun, the larger the gravity

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?
