The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as
P V = n RT
rearranging the equation by dividing both side by "RT", we get
PV/(RT) = nRT/(RT)
n = PV/(RT)
inserting the values of pressure, volume and temperature, we get number of moles.
A. Refraction, meaning the same thing...it just passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped this helps you :)
Short answer: Refraction
They are a variable that changes as a result of the changes in the manipulated variable
<h3><u>Answer;</u></h3>
126 joules
<h3><u>Explanation;</u></h3>
Potential energy is the energy possessed by a body while at rest.
It is calculated by the formula m×g×h; where m is the mass, h is the height and g is the gravitational acceleration, 10N/kg
Potential energy = m×g×h
= 3.0 × 4.2 × 10
<u>= 126 joules</u>
Answer:
The wavelength of the standing wave is 3 m.
Explanation:
Given that,
Length = 6 m
Nodes = 4
We need to calculate the wave length
Using formula of nodes


Where, l = length
n = number of nodes
= wavelength
Put the value into the formula


Hence, The wavelength of the standing wave is 3 m.
