There are 35 black holes known in the Andromeda galaxy!
I believe it is, All of the above.
Answer:
a.3.20m
b.0.45cm
Explanation:
a. Equation for minima is defined as:
Given , and :
#Substitute our variable values in the minima equation to obtain :
#draw a triangle to find the relationship between and .
#where
Hence the screen is 3.20m from the split.
b. To find the closest minima for green(the fourth min will give you the smallest distance)
#Like with a above, the minima equation will be defined as:
, where given that it's the minima with the smallest distance.
#we then use to calculate =4.5cm
Then from the equation subtract from :
Hence, the distance is 0.45cm
The correct option is this: THIS IS THE DEMONSTRATION OF BOYLE'S LAW. AS THE VOLUME INCREASES, THE PRESSURE DECREASES AND THE MARSHMALLOW WILL GROW LARGER.
Boyle's law states that the volume of a gas is inversely proportional to the pressure of the gas at constant temperature. The law explains the relationship between the volume and pressure of a gas at constant temperature.
How do you mean? I mean, physic professors teach physics...
