What is the wavelength of a wave with a frequency of 262 hz and a speed of 343 m/s A. 89,8666 m/s
B. 0.76 m
C. 1.11 x 10^ -5 m
D. 1.3 m

Heya!!

For calculate wavelength, lets applicate formula:

                                                   Δ   Being   Δ

                                            f = Frequency = 262 Hz

                                            v = Velocity = 343 m/s

                                              = Wavelenght = ?

⇒ Let's replace according the formula:

⇒ Resolving

Result:

The wavelength is 1,3 meters.

Good Luck!!

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

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.
