A long string carries the wave; a segment of the string measuring 6.00 meters in length and weighing 180 grams contains four full wavelengths. The string vibrates sinusoidally at a 50.0 Hz frequency with a 15.0 cm peak-to-valley displacement. The vertical distance between the farthest positive and negative positions is known as the "peak-to-valley" distance. The function that describes this wave traveling in the positive x direction is $y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right)$ .

$\begin{aligned}& f=500 \mathrm{~Hz} \\&\mu=\frac{180 \times 10^{-3}}{6}=3 \times 10^{-2} K g / m \\&2 A=15 \times 10^{-2} m \\&A=7.5 \times 10^{-2} m \\&4 \lambda=6, \lambda=3 / 2 m \text {. and } v=f \lambda=75 m / \mathrm{sec} \\&\omega=2 \pi f=100 \pi \text { also } K=\frac{\omega}{v}=\frac{4 \pi}{3}\end{aligned}$

If phase constant is $\phi$ then

$\therefore$ equation is $y=7.5 \times 10^{-2} \sin \left[100 \pi t-\frac{4 \pi}{3} x+\phi\right]$

∴ equation is $y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right)$

A wave is a disturbance that moves from one location to another, carrying energy but not always matter.
The square of the equation provides a probability density map of the locations where an electron has a specific statistical likelihood to be at any given moment in time. Wave functions have no direct physical meaning.

A man with mass 82 kg runs at a speed of 2.8 ms How much kinetic energy does he have?? A.114.8 B.221.8 C.321.4 D.642.9

Delvig [45]

Use the formula for kinetic energy.
KE=1/2mv^2
KE=1/2*(82kg)*(2.8m/s)^2
KE=321.4 J
The answer is C

A load of mass 5kg is raised through a height of 2m. (g=10mls)

s2008m [1.1K]

The gain in gravitational potential energy of the mass = 100 kg m^2 / s^2.

<u>Explanation:</u>

Gravitational potential energy is an energy in which an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the Earth's surface where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

The formula for the gravitational potential energy is the product of mass, gravity, and height.

GPE = m *g *h

where m represents mass in kg,

g represents the gravity,

h represents the height.

GPE = 5 * 10 * 2 = 100 kg m^2 / s^2.

What happens to the temperature of a substance during a phase change?

german

During a phase change, the temperature remains constant. obviously all the heat is used in phase transformation.
