Heya!!
For calculate wavelength, lets applicate formula:

<u>Δ Being Δ</u>
f = Frequency = 262 Hz
v = Velocity = 343 m/s
= Wavelenght = ?
⇒ Let's replace according the formula:

⇒ Resolving

Result:
The wavelength is <u>1,3 meters.</u>
Good Luck!!
The net force on the rocket is 864 N
Explanation:
The net force acting on the rocket can be calculated by using Newton's second law of motion, which states that:
F = ma
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the rocket in this problem, at a certain instant we have:
m = 48 kg

Therefore, the force on the rocket is
