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!!

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

i think it's 35 meters
