Explanation:

I will do two of each as examples.

Boyle's law says that at constant temperature, the product of the initial pressure and volume equals the product of the final pressure and volume.

1. P₁ V₁ = P₂ V₂

(1.5 atm) (10.0 L) = (0.75 atm) V

V = 20.0 L

2. P₁ V₁ = P₂ V₂

(100.0 kPa) (500.0 mL) = P (1,000.0 mL)

P = 50.0 kPa

Charles' law says that at constant pressure, the quotient of the initial volume and temperature equals the quotient of the final volume and temperature.

6. V₁ / T₁ = V₂ / T₂

(10.0 L) / (1500 K) = V / (750 K)

V = 5.0 L

7. V₁ / T₁ = V₂ / T₂

(500.0 mL) / (100 K) = (1000.0 mL) / T

T = 200 K

Explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are; lever, wedge, pulley, screw, wheel and axle, and inclined plane.

Inclined plane is a simple machine set at an angle and then used to lift an object.

In Physics, the velocity ratio of a simple machine is calculated as a ratio of the distance moved by the effort to the vertical distance through which a load is raised.

Mathematically, the velocity ratio of an inclined plane of angle Ɵ, acting as a simple machine is given by the formula;

Velocity ratio (V.R) = 1/sinƟ

Basically, an increase in the angle of inclination (measured in degrees) of an inclined plane increases its velocity ratio.

Josh and Jake are both helping to build a brick wall which is 6 meters in height. They each lay 250 bricks, but Josh finishes th

<span>Each laid 250 bricks but while Jake was still working, Josh was lounging in the shade. Josh has more power but that power was only on for 3 hours out of 4.5. Obviously Josh could get more done is less time as long as he keeps working. Jake will get the hang of it soon.</span>

Many chemical reactions release energy. Suppose that at the beginning of a reaction, an electron and proton are separated by 0.1

ludmilkaskok [199]

Answer:

$1.189eV$

Explanation:

The electric potential energy is the potential energy that results from the Coulomb force and is associated with the configuration of two or more charges. For an electron in the presence of an electric field produced by a proton, the electric potential energy is defined as:

$U=\frac{kq_{e}q_{p}}{r}$

where $q_{e}$ is the electron charge, $q_{p}$ is the proton charge, r is the separation distance between the charges and k is the coulomb constant.

Knowing this, we can calculate how much electric potential energy was lost:

$\Delta U=U_{f}-U{i}\\\Delta U=\frac{kq_{e}q_{p}}{r_{f}}-\frac{kq_{e}q_{p}}{r_{i}}\\\Delta U=kq_{e}q_{p}(\frac{1}{r_{f}}-\frac{1}{r_{i}})\\\Delta U=(8.99*10^9\frac{Nm^2}{C^2})(-1.60*10^{-19}C)(1.60*10^{-19}C)(\frac{1}{0.105*10^{-9}m}-\frac{1}{0.115*10^{-9}m})\\\Delta U=1.90*10^{-19}J*\frac{6.2415*10^{18}eV}{1J}=1.189eV$
