Answer:

42 m/s

Explanation:

by definition of the velocity(speed) of a wave,

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f.

V= fλ

frequency - number of occurances in a unit time

(check the graph)

velocity=frequency*wave.length\\=14Hz*3m\\=42 ms^{-1}

4. A box of books weighing 325 N moves at a constant velocity across the floor when the box is pushed with a force of 425 N exer
Rudik [331]

Answer:

0.61°

Explanation:

Since the box move at constant velocity, it means there is no acceleration then we can say it has a balanced force system.

Pulling force= resistance force

From the formula for pulling force,

F(x)= Fcos(θ)

= 425×cos(35.2)

=347N

The force exerted downward at an angle of 35.2° below the horizontal= Fsin(θ)= 425sin(35.2)

=425×0.567=245N

Resistance force= (325N+ 245N) (α)= 570N(α)

We can now equates the pulling force to resistance force

570 (α)= 347N

(α)= 347/570

= 0.61
