Fig on the left shows a stationary source emitting the waves. Fig on the right shows the waves in the medium as the source starts moving towards the left. If you were an observer to the left of the source, what would you observe about the wavelength and the frequency of the waves? A. Wavelength-Increase, Frequency-Decrease

B. Wavelength-Increase, Frequency-Increase

C. Wavelength-Decrease, Frequency-Increase

D. Wavelength-Decrease, Frequency-Decrease

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

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.
