Answer: Charles's law
Explanation:
Charles's law is one of the gas laws, and it explains the effect of temperature changes on the volume of a given mass of gas at a constant pressure. Usually, the volume of a gas decreases as the temperature decreases and increases as the temperature also increases.
Mathematically, Charles's law can be expressed as:
V ∝ T
V = kT or (V/T) = k
where v is volume, T is temperature in Kelvin, and a k is a constant.
i think photons with shorter wavelengths have larger speed.
I apologise if its incorrect.
Answer:
The frequency of the wheel is the number of revolutions per second:
f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz
And now we can calculate the angular speed, which is given by:
\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s in the clockwise direction.

Answer:
It will require 14.715 N of force to hold the cartoon beneath the water.
Explanation:
Given the the volume of cartoon is 1.5 liters.
We need to find the force required to hold this cartoon beneath the water.
As we know from the Archimedes principle that the net force is equal to the volume of liquid displaced.
Given volume of the cartoon is 1.5 liters. So, 1.5 liters of water will be displaced.
And we know the density of the water is
. That is 
And 

So, it will require 14.715 N of force to hold 1.5 liter volume of cartoon beneath the water.
<span>The answer is D. Photons are individual units of light. In order for an image to exist, they need to be absorbed by something that can use them to create the picture. In old days, this was Silver Nitrate applied to film, but today it is the digital camera itself that does this. Electrons are something different entirely, so A and B are wrong, and C is wrong because the photons are not ejected by the image sensor.</span>
