Name the two types of vaporization and explain the difference between them. Give one example of each. ​
kolezko [41]
Evaporation and boiling.
Evaporation refers to only the surface level turning it into a gas and the vaporization pressure of the liquid remains low.
When a substance boils it’s pressure is high and the surface evaporated along with the rest of the liquid at an equal rate. A sign of boiling is the presence of bubbles, which occur only in the process of boiling and not in evaporation.
A example of boiling is heating water up to the point until you see steam and bubbles.
A example of evaporation is the melting of an ice cube.

A cat dozes on a stationary merry-go-round, at a radius of 5.7 m from the center of the ride. Then the operator turns on the rid
tatyana61 [14]

Answer:

0.76

Explanation:

we are given:

radius (r) =5.7 m

speed (s) = 1 revolution in 5.5 seconds

acceleration due to gravity (g) = 9.8 m/s^{2}

coefficient of friction (Uk) = ?

 we can get the minimum coefficient of friction from the equation below

centrifugal force = frictional force

m x r x ω^{2} = Uk x m x g

r x ω^{2} = Uk x g

Uk = \frac{ r x ω^{2} }{g}

where ω (angular velocity) = \frac{2π}{time}

= \frac{2π }{5.5} = 1.14

Uk = \frac{ 5.7 x 1.14^{2} }{9.8} = 0.76

A stretched spring has 5184 J of elastic potential energy and a spring constant of 16,200 N/m. What is the displacement of the s
Ira Lisetskai [31]
The elastic potential energy (Ep) is given by Ep =  \frac{1}{2}*k*x^2

Data:
Ep = 5184 J
k = 16200 N/m
x (displacement) = ?

Solving:
Ep = \frac{1}{2}*k*x^2
5184 = \frac{1}{2}*16200*x^2
5184*2 = 16200x^2
10368 = 16200x^2
16200x^2 = 10368
x^2 =  \frac{10638}{16200}
x^2 = 0.64
x =  \sqrt{0.64}
\boxed{\boxed{x = 0.8\:m}}\end{array}}\qquad\quad\checkmark
