The velocity, frequency and wavelength of a wave are related by:
v = fλ
v = 32 x 0.5
v = 16 m/s
The answer is B.
The force of the object with the given mass and acceleration is determined as 10 N.
<h3>
Force of the object</h3>
The force of the given object is calculated from Newton's second law of motion as follows;
F = ma
where;
- m is mass of the object = 5 kg
- a is acceleration of the object = 2 m/s²
F = 5 x 2 = 10 N
Thus, the force of the object with the given mass and acceleration is determined as 10 N.
The complete question is below:
Rearranging the equation m = F/a and solve for F, m= 5Kg and a= 2 m\s2
