Solving for h means we write the equation in such a way that h is isolated from other variables. It is done as follows:
(P = mgh) 1/mg
P/mg = mgh/mg
h = P/mg
Therefore, the correct answer from the choices listed above is option C, h = p/mg.
Hope this answers the question. Have a nice day.
Answer: Zoey needs 168 square feet if carpet squares.
Step-by-step explanation:
Zoey wants to cover her bedroom floor with carpet squares. Each square has an area of 1 square foot.
The formula for determining the area of a rectangle is expressed as
Area = length × width
Her bedroom measures 12 feet by 14 feet. Therefore, the area of her bedroom would be
12 × 14 = 168 square feet.
Therefore, the number of carpet squares that Zoey needs would be
168/1 = 168 square feet
Should be 262.5.105 times 2=210 for one hour.105 divided by 2 to have 1\4=52.5.210+52.5 equals 262.5
Answer:5.8
Step-by-step explanation:
Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
