An experiment is designed to investigate the relation between the pressure and temperature in a tank that has a constant volume

and mass. (The equation of state for air is pV=m R T, where p is the pressure, V is volume, m is mass, R is the gas constant, and T is the temperature.) A polynomial relation was suggested for the relation between p and T. You noticed that as you increase the order of the polynomial the error between the curve fit and the measured data decreases. What polynomial order is best to use

Answer:

3rd order polynomial

Explanation:

Given that the increase in the order of the polynomial the error between the curve fit and measured data will decreases hence  :

The polynomial order that is best to use is the 3rd order polynomial, this is because using a 3rd order polynomial will produce a less variance and a low Bias

How does Newton’s third law of motion relate action and reaction forces? They produce a net force of zero. They are equal and op
Paladinen [302]

<u>Answer:</u>

The correct answer option is: they are equal and opposite.

<u>Explanation:</u>

A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.

And according to the Newton's third law: for every action, there is an equal and opposite reaction.

For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.

Canola oil is less dense than water, so it floats on water, but its index of refraction is 1.47, higher than that of water. When
kupik [55]

Answer:

therefore critical angle c= 69.79°

Explanation:

Canola oil is less dense than water, so it floats over water.

Given n_{canola}= 1.47

which is higher than that of water

refractive index of water n_{water}=1.33

to calculate critical angle of light going from the oil into water

we know that

sinc= \frac{n_{water}}{n_{canola}}

now putting values we get

sinc= \frac{1.33}{1.47}

c= sin^{-1}(\frac{1.33}{1.47} )

c=69.79°

therefore critical angle c= 69.79°
