The formula v=fλ can be used here.

326=2500*λ

Note the 2500 as 2.5kHz is 2.5 thousand Hz.

λ = 326/2500
= 0.1304m = 0.130m

Answer:

a. $1.70\times 10^{20} N$ b. $6.94\times 10^{-3}m/s^2$ c. $2.62\times 10^{-5} m/s^2$

Explanation:

Use Gravitational Force:

$F= G\frac{Mm}{r^2}$

Use values given to have the results.

$g=\frac{F}{m}$

Use m as the mass of the Moon. Using values of a. and m you have the answer.

$g = \frac{F}{M}$
