What is the wavelength of a wave with frequency 1.4 x 1010Hz?

2.143 × 10^-2m

Explanation:

The wavelength, denoted by λ, can be determined using the formula;

λ = v/f

Where; λ = wavelength (m)

v = speed of light (3 × 10^8m/s)

f = frequency

According to the provided information, f = 1.4 x 10^10Hz, v = 3 × 10^8m/s

Hence, λ = v/f

λ = 3 × 10^8/ 1.4 x 10^10

λ = 2.1428 × 10^(8-10)

λ = 2.143 × 10^-2m

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
