a light wave travels at 3.0 x 10^8 m/s. if the wavelength of a red wave is 700 x 10^-9m, what is the frequency?
asambeis [7]

Frequency  =  (speed) divided by (wavelength)

                 = (3 x 10⁸ m/s)  /  (700 x 10⁻⁹ m)

                 =  (3 / 700) x 10¹⁷ ( per sec )

                 =    4.286 x 10¹⁴  per sec  =  4.286 x 10¹⁴ Hz.

                                                           =      42,860 GHz .

A 06-C charge and a 07-C charge are apart at 3 m apart. What force attracts them?​
Vlad [161]

Answer:

Force of 37.8 × 10^(6) N attracts the two charges

Explanation:

The force between two charges is given by

F = k*q1*q2/r²

Where q1 and q2 are 0.06 C and 0.07 C.

r is the distance between q1 and q2 which is equal to 3 m

k is a constant = 9 × 10^(9) N.m²/C²

F = (9 × 10^(9) × 0.06 × 0.07)/3²

F = 37.8 × 10^(6) N
