Answer:

Explanation:

If 20 gauge shell is placed in a 12 gauge shotgun it will cause damage and serious injury. If 20 gauge shell is placed the it will slip pass the chamber and and when fired it will cause ersonal damage. So to avoid the damage you will have to see what gauge is written on the shell and check if it is same as on gun barrel. Be careful in choice of ammunition.

Answer:

The temperature of the gas is 1197.02 K

Explanation:

From ideal gas law;

PV = nRT

Where;

P is the pressure of the gas

V is the volume of the gas

R is ideal gas constant = 8.314 L.kPa/mol.K

T is the temperature of the gas

n is the number of moles of gas

Volume of the gas in the cylindrical container = πr²h

Given;

r = 6/2 = 3 cm = 0.03 m

h = 11 cm = 0.11 m

V = π × (0.03)² × 0.11 = 3.11 × 10⁻⁴ m³ = 0.311 L

number of moles of oxygen gas = Reacting mass / molar mass

$=\frac{0.1}{32} = 0.003125, moles$

$T = \frac{PV}{nR} = \frac{100X0.311}{0.003125X8.314} =1197.02K$

Therefore, the temperature of the gas is 1197.02 K

A device that uses electricity and magnetism to create motion is called a _________motor,magnet,generator . In a reverse process

lawyer [7]

A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & <span>In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor
2nd Blank = Electromagnetism

Hope this helps!</span>

Which statements describe the characteristics of asteroids? Check all that apply. formed 4.6 billion years ago orbit the Sun bey

choli [55]

Answer:

formed 4.6 billion years ago

orbit the Sun

range in size from a few feet to more than 500 miles across

most are found in the asteroid belt

Explanation:

Asteroids are rocky bodies orbiting the sun. Asteroids are irregular is shape and size. The size varies from few feet to 500 miles across. Majority of the asteroids lie in asteroid belt which lies between the orbits of Mars and Jupiter. These are though to be remains of unformed planet about 4.6 billion years ago due to high gravitational pull of Jupiter. The largest asteroid is Ceres which is also a dwarf planet. The mass of the entire asteroid belt is just 4% the mass of the moon.

A rigid, uniform bar with mass mmm and length bbb rotates about the axis passing through the midpoint of the bar perpendicular t

Pie

Answer:

$I = \frac{mvb}{6}$

Explanation:

we know angular velocity in terms of moment of inertia and angular speed

$L = I$ ω .... (1)

moment of inertia of rod rotating about its center of length b

$I = \frac{ mb^2}{12}$ ........ .(2)

using v = ωr

where w is angular velocity

and r is radius of rod which is equal to b

so we get 2v = ωb

ω = 2v/b ................. (3)

here velocity is two time because two opposite ends are moving opposite with a velocity v so net velocity will be 2v

put second and third equation in ist equation

$L = \frac{mb^2}{12}$ × $\frac{2v}{b}$

so final answer will be $L = \frac{mvb}{6}$
