A sound wave is direct at a wall. In 20 seconds, 200 wave cycles hit the wall.
Tems11 [23]

Answer:

Frequency=10 Hz

Period=0.1 s

Explanation:

Frequency of a wave is the number of complete cycles per unit time. Usually, frequency is cycles per second, with unit as Heartz

Given cycles of the wave as 200 and time as 20 seconds

Frequency=200÷20=10 cycles per second

Therefore, frequency is 10 Hz

Period is usually the reviprocal of frequency hence reciprocal of 10 Hz will be 1/10=0.1 s

Three forces act on a statue. Force F⃗ 1F→1 (magnitude 45.0 NN) points in the +x-direction, Force F⃗ 2F→2 (magnitude 105 NN) poi
Trava [24]

Answer:

Resultant force = (232.93î + 246.10j) N

x-component of the resultant force = (+232.93î) N

y-component of the resultant force = (+246.1j) N

Explanation:

The net external force on the statue is equal to the resultant force on the statue.

And the resuphant force is a vector sum of all the other forces acting on the statue.

Force 1 = (45î) N

Force 2 = (105j) N

Force 3 = (235cos 36.9°)î + (235 sin 36.9°)j = (187.93î + 141.10j) N

Resultant force = (Force 1) + (Force 2) + (Force 3)

Resultant force = 45î + 105j + (187.93î + 141.10j) = (232.93î + 246.10j) N

Hope this helps!!!
