What is the frequency of a mechanical wave that has a velocity of 1.70 m/s and a wavelength of 12.05 m? (3 decimal places)

0.141Hz

Explanation:

Given parameters:

Velocity of the wave  = 1.7m/s

Wavelength  = 12.05m

Unknown:

Frequency of the wave = ?

Solution;

To solve this problem, we use the wave velocity equation which is expressed below;

            V  = F ∧  

V is the velocity

F is the frequency

∧ is the wavelength

 Now insert the parameters and solve;

           1.7  = F x 12.05

            F  = 0.141Hz

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
