Dogs have the ability to hear sounds up to 40,000 hz. If the sound is 340 m/s what is the most extreme wavelength a dog can detect a. 8.5 x 10^-3 m
b. 1.2 x 10^2 m
c. 2.0 x 10^4 m
d. 1.4 x 10^7 m

velocity= frequency×wavelength

wavelength= velocity/frequency

wavelength= 340/40,000

= 8.5×10^-3m

answer: he got 23

explanation:

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.
