Mechanical advantage = (output force) / (input force)

MA = (2,000 N) / (120 N)

<em>MA = 16.67</em> (16 and 2/3)

Wave is traveling at 60 cm/second and has a wavelength of 15 cm, what is the frequency?

emmasim [6.3K]

The frequency of the wave is 4 Hz

Explanation:

The relationship between wave, frequency and speed of a wave is given by the equation:

$v=f \lambda$

where

v is the speed of the wave

f is the frequency

$\lambda$ is the wavelength

For the wave in this problem, we have:

$v=60 cm/s$ is the speed

$\lambda=15 cm$ is the wavelength

Solving the equation for f, we find its frequency:

$f=\frac{v}{\lambda}=\frac{60 cm/s}{15 s}=4 s^{-1} = 4 Hz$

A transverse mechanical wave is traveling along a string lying along the x-axis. The displacement of the string as a function of

kvv77 [185]

The wavelength of the wave is 1.16m and the velocity is 23.64m/s.

To find the answer, we have to know more about the Transverse waves.

<h3>How to find different parameters of a wave?</h3>

The displacement of the string as a function of position and time, y(x,t), when the wave traveling along a string lying along the x-axis is given as,

$y(x,t)=0.048sin(5.40x-128t)$

Comparing this with the general form of wave equation, we get,

$amplitude, a=0.048m\\wave vector, k=5.40\\angular frequency,w=128Hz$

We have to find the wavelength of the wave, for this, we have the expression as,

$k=\frac{2\pi }{wavelength} \\\\wavelength=\frac{2\pi }{k} =\frac{2*3.14}{5.40} \\\\wavelength=1.16m$

We have to find the velocity of the wave,

$v=frequency*wavelength\\2\pi f=w, thus,\\f=\frac{w}{2\pi } =\frac{128}{2*3.14}=20.38s^{-1}\\\\v=1.16*20.38=23.64m/s$

Thus, we can conclude that, the wavelength of the wave is 1.16m and the velocity is 23.64m/s

A circuit has resistors R 1 = 468 Ω and R 2 = 125 Ω R1=468 Ω and R2=125 Ω , and two batteries V 1 = 12.0 V and V 2 = 3.00 V V1=1

Greeley [361]

Answer:

0.0192A

Explanation:

Since, the reading of the galvanometer is 0 A, the voltage across the resistance R will be:

Step 1

VR = V2

VR = 3.00v

Step 2

Calculating the current through the resistance R as below,

IR = V1 - V2 /R1

IR = 12 - 3 /468

IR =0.0192A

Find the instantaneous acceleration at t=ls for an object moving along a straight axis with velocity function:

Maru [420]

The answer is A.
Explanation:
We know that the average acceleration a for an interval of time Δt is expressed as:

a = Δv
Δt
where Δv is the change in velocity that occurs during Δt.
e formula for the instantaneous acceleration a is almost the same, except that we need to indicate that we're interested in knowing what the ratio of Δv to Δt approaches as Δt approaches zero.

We can indicate that by using the limit notation.

So, the formula for the instantaneous acceleration is:

a = lim Δv
Δt→0 Δt

The current in a hair dryer measures 15 amps. The resistance of the hair dryer is 14 ohms. What is the voltage?

ZanzabumX [31]

We have that there is a formula connecting these three. V=I*R where V is voltage, I is the current and R is the resistance. Substituting, we get that V=210 Volta, which is the unit of measurement for voltage. You can think of the relationship in the following way : The energy of the field is equal to the flow of the field times the resistance that it meets.
