A wave has a frequency of 58 hz and a speed of 31 m/s. what is the wavelength of this wave?

Physics

First remember the equations for wavelength and frequencies:

v = fw

Now let's plug in what we know from the question:

(31 m/s) = (58 Hz) w

Use the calculator and you'll get the value of wavelength, w! If you comment your answer I'll check it for you. :)

Manuel is holding a 5kg box. How much force is the box exerting on him?In what direction
soldi70 [24.7K]
The force the box is exerting on Manuel is the weight of the box, downward:
W=mg=(5 kg)(9.81 m/s^2)=49.05 N
and this force is perfectly balanced by the constraint reaction applied by Manuel's hand, pushing upward.

Two astronauts push on a satellite. One pushes in the positive x direction with a force of 42 N, and the other pushes in the pos
inessss [21]

The vectors adition we can find the magnitude of the force applied by the other astronaut is  11.25 N in the y direction

 

Parameters given

  • Force of an astronaut Fₓ = 42 N
  • Angle θ = 15º

To find

  • Force another astronaut

The force is a vector magnitude for which the addition of vectors must be used, a very efficient method to perform this sum is to add the components of each vector and devise constructing the resulting vector using trigonometry and the Pythagorean theorem.

Let's use trigonometry to find the other force

            tan θ = \frac{F_y}{F_x}

            F_ y = Fₓ tan θ

let's calculate

            F_y = 42 tan 15

            F_y = 11.25 N

Using the summation of vectors we can find the magnitude of the force applied by the other astronaut is 11.25 N in the y direction
