A wave with a frequency of 60.0 Hz travels through rubber with a wavelength of .90 m. What is the speed of this wave?
gizmo_the_mogwai [7]

Answer:

Speed of wave 54 ms⁻¹.

Explanation:

Given data:

Frequency of wave = 60 Hz

Wavelength of wave = 0.90 m

Speed = ?

Solution:

Formula

speed = wavelength × frequency

Now we will put the values in formula.

v = f × λ

Hz =  s⁻¹

v = 60 s⁻¹ × 0.90 m

v = 54 m s⁻¹

I want to make a Twinkie splat when I throw it off a building. Because Twinkies are notoriously hard to crush, I want it to hit
Monica [59]

Answer:

s=253.6524712 \approx 253.7

Explanation:

From the question we are told that

Initial speedv=8ft/s

Final speed v=128ft/s

Generally the Newtons  equation of motion is mathematically represented by

V_f^2-V_0^2=2as

with

Therefore

a=g=>9.81m/s^2\\a=32.17ft/s^2

Therefore

128^2-8^2=2*(32.17)*s

16320=2*(32.17)*s

s=\frac{16320}{2*(32.17)}

s=253.6524712 \approx 253.7

What is the magnitude of the initial velocity?
lesya692 [45]

Magnitude of initial velocity

<em>To calculate the </em><em>magnitude</em><em> of the </em><em>velocity</em><em> at any point in time, multiply the constant acceleration rate times the time difference and then add it to the </em><em>initial velocity.</em><em> As an example, if you dropped a rock off a cliff, its </em><em>velocity</em><em> increases by 32 feet per second, every second.</em>

<em />

<h2><em>Hope this helps you a lot ...</em></h2><h2><em>Good day :)</em></h2>
