Take the stone's position at ground level to be the origin, and the downward direction to be negative. Then its position in the air
at time
is given by

Let
be the depth of the well. The stone hits the bottom of the well after 5.00 s, so that

The volume of rain that fells in the field is simply given by the area of the field, which is

multiplied by the height of rain that fell, which is

Therefore, the volume is

FMRI creates the images or brain maps of brain functioning by setting up and utilizing an advanced MRI scanner in such a way that increased blood flow to the activated areas of the brain shows up on the MRI scan. The MRI scanners do not actually detect blood flow or other metabolic processes.
Answer:
A charge of -5.02 nC is uniformly distributed on a thin square sheet of nonconducting material of edge length 21.8 cm. "What is the surface charge density of the sheet"?
Explanation:
Surface charge density is a measure of how much electric charge is accumulated over a surface. It can be calculated as the charge per unit area.
We will convert all parameters in SI units.
Charge = Q = -5.02nC
Q = -5.02×
C
As it is clear from question that Sheet is a square (All sides will be of equal length)
Area = A = (21.8×
m) (21.8×
m) = 4.75×
m²
A = 4.75×
m²
Surface charge density = Q/A
Surface charge density = (-5.02×
C)/(4.75×
m²)
Surface charge density = -1.057×
C
They did not believed Galileo's discoveries because religiouse reasons the preast said that all the bible is true but Galileo despised it.
