Answer:

The force exerted on a given area.

Option B is the right option.

Explanation:

<h2>About pressure</h2>

Pressure is defined as force acting per unit area. It's SI unit is Pascal or N/m^2.

Formula to find pressure is:

$\frac{thrust(f)}{area(a)}$

The force acting perpendicular on a surface is called the thrust. It is a vector quantity.

One Pascal pressure

One Pascal pressure is defined as the pressure exerted in a surface of area m^2 by the thrust of 1 N

Hope this helps ..

Find the net charge of a system consisting of 6.25×10^6 electrons and 7.75×10^6 protons. Express your answer using three signifi

jok3333 [9.3K]

Answer:

2.40 x 10⁻¹³ C

Explanation:

$n_{e}$ = number of electrons = 6.25 x 10⁶

$q_{e}$ = charge on electron = - 1.6 x 10⁻¹⁹ C

$n_{p}$ = number of protons = 7.75 x 10⁶

$q_{p}$ = charge on proton = 1.6 x 10⁻¹⁹ C

Net charge is given as

Q = $n_{e}$ $q_{e}$ + $n_{p}$ $q_{p}$

Q = (- 1.6 x 10⁻¹⁹) (6.25 x 10⁶) + (1.6 x 10⁻¹⁹) (7.75 x 10⁶)

Q = 2.40 x 10⁻¹³ C

Hii I need help ASAP with this physics question

Readme [11.4K]

Between the top of the first and the top of the second loop, the coaster has lost potential energy = mgh, where h = 22.2 - 15 = 7.2m

This energy would have converted to Kinetic. Write out an equation and the masses will cancel out. Does that hint help you to find the solution? If not, I will give you another hint.
