What is meant by the number of complete oscillation made by an oscillating body in 10 seconds is 500 complete oscillations is that the frequency of the oscillating body is 50Hz

<h3>What is frequency?</h3>

Frequency of an oscillating body can be defined as the number of complete oscillations per unit time

Frequency is measured in hertz (Hz).

Also, the frequency of 1Hz is one oscillation per second.

frequency = number of oscillations/ time taken

frequency = 500/10 = 50 Hz

Thus, what is meant by the number of complete oscillation made by an oscillating body in 10 seconds is 500 complete oscillations is that the frequency of the oscillating body is 50Hz

The equation that describes a transverse wave on a string is y = (0.0120 m)sin[(927 rad/s)t - (3.00 rad/m)x] where y is the disp

dem82 [27]

Answer:

Speed, v = 312.34 m/s

Explanation:

The equation that describes a transverse wave on the string is given by :

$y=0.0120\ msin[(927\ rad/s)t-(3\ rad/m)x]$ ..............(1)

Where

y = displacement of a string particle

x = position of the particle on the string

The wave is travelling in the +x direction. We have to find the speed of the wave.

The general equation of traverse wave is given by :

$y=A\ sin(kx-\omega t)$ ................(2)

On comparing equation (1) and (2) we get,

k = 3 rad/m

Since, $k=\dfrac{2\pi}{\lambda}$

$\lambda=\dfrac{2\pi}{3}$ ..............(3)

Also, $\omega=927\ rad/s$

Since, $\omega=2\pi \nu$

$\nu=\dfrac{927}{2\pi}$ ...............(4)

Speed of the wave is the product of frequency and wavelength i.e.

$v=\nu\times \lambda$

Using equation (3) and (4), the speed of the wave can be calculated as :

$v=\dfrac{927}{2\pi}\times \dfrac{2\pi}{3}$

v = 312.34 m/s

Hence, the speed of the transverse wave is 312.34 m/s

9.58 A spring of equilibrium length L1 and spring constant k1 hangs from the ceiling. Mass m1 is suspended from its lower end. T

andrey2020 [161]

Answer:

The distance of m2 from the ceiling is L1 +L2 + m1g/k1 + m2g/k1 + m2g/k2.

See attachment below for full solution

Explanation:

This is so because the the attached mass m1 on the spring causes the first spring to stretch by a distance of m1g/k1 (hookes law). This plus the equilibrium lengtb of the spring gives the position of the mass m1 from the ceiling. The second mass mass m2 causes both springs 1 and 2 to stretch by an amout proportional to its weight just like above. The respective stretchings are m2g/k1 for spring 1 and m2g/k2 for spring 2. These plus the position of m1 and the equilibrium length of spring 2 L2 gives the distance of L2 from the ceiling.

Let T be a linear transformation from a vector space V with dimension 11 onto a vector space W with dimension 7. What is the dim

erica [24]

Answer:

The dimension of the nullspace of T = 4

Explanation:

The rank/dimension theorem is explains that:

Suppose V and W are vector spaces over F, and T:V → W is linear. If V is finite dimensional, then

nullity(T) + rank(T) = dim(V).

rank(T) = dimension of T = dim(T) = dim(W) = 7

nullity(T) = dimension of the nullspace of T = dim(T) = ?

dim(V) = 11

nullity(T) = dim(V) - dim(T) = 11 - 7

nullity(T) = 4.
