For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, it would have a speed of 600 m/s.

Answer:

The speed of the wave at the given wavelength and frequency is 60 m/s.

The given parameters;

wavelength of the wave, λ = 0.5 m

frequency of the wave, f = 120 Hz

The speed of the wave is calculated by applying general wave equation as shown below;

v = fλ

where;

v is the speed of the wave

v = 120 x 0.5

v = 60 m/s

Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.

Friction: a 50-kg box is resting on a horizontal floor. A force of 250 n directed at an angle of 30. 0° below the horizontal is
sergejj [24]

The net forces on the box parallel and perpendicular to the surface, respectively, are

∑ F[para] = (250 N) cos(-30.0°) - F[friction] = (50 kg) a

and

∑ F[perp] = F[normal] + (250 N) sin(-30.0°) - F[weight] = 0

where a is the acceleration of the box. (We ultimately don't care what this acceleration is, though.)

To decide whether the friction here is static or kinetic, consider that when the box is at rest, the net force perpendicular to the floor is

∑ F[perp] = F[normal] - F[weight] = 0

so that, while at rest,

F[normal] = (50 kg) g = 490 N

Then with µ[s] = 0.40, the maximum magnitude of static friction would be

F[s. friction] = 0.40 (490 N) = 196 N

so that the box will begin to slide if it's pushed by a force larger than this.

The horizontal component of our pushing force is

(250 N) cos(-30.0°) ≈ 217 N

so the box will move in our case, and we will have kinetic friction with µ[k] = 0.30.

Solve the ∑ F[perp] = 0 equation for F[normal] :

F[normal] + (250 N) sin(-30.0°) - F[weight] = 0

F[normal] - 125 N - 490 N = 0

F[normal] = 615 N

Then the kinetic friction felt by the box has magnitude

F[k. friction] = 0.30 (615 N) = 184.5 N ≈ 185 N

Walter and Trina are planning a campus event focused on equity and inclusion. Several students would like to help with the event
Shkiper50 [21]

The following speech is not necessary aligned with the topics of equity and inclusion that are planned for the event:

  • The importance of untimed tests for all students.

The speech can be considered related to equity because it is about all students, but the topic it talks about is not a very important problem in relation to inclusion and equity. However, all the other options are related.

Inclusion means that everyone is included, no one is left out. Equity means that everything is the same for every one, there are no preferences, everything is fair for everyone.
