What is the difference between a sprain and a dislocation

1 answer:

8 0

A sprain is a minor injury that only hurts doesnt really do much damage. but a dislocation is the opposite it is a bone in the body moving to a different place so lets say your elbow was in a correct area and you fell off your table and landed on your elbow and made it shift a different way.

Answer:

v = 54.2 m / s

Explanation:

Let's use energy conservation for this problem.

Starting point Higher

Em₀ = U = m g h

Final point. Lower

$Em_{f}$ = K = ½ m v²

Em₀ = Em_{f}

m g h = ½ m v²

v² = 2gh

v = √ 2gh

Let's calculate

v = √ (2 9.8 150)

v = 54.2 m / s

The reason why the position of an electron cannot be measured with absolute precision is:

LenKa [72]

They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.

<h2><u>ANSWER</u></h2>

$\\$

Two isotopes of helium ( helium 3 and helium 4) show superfluidity whem they are liquified by cooling to a very low specific temperature. One isotope of rubidium and lithium posses this property at low temperature.

A moving freight car collides with an identical one that is at rest. If momentum is conserved, what happens to the second car af

yKpoI14uk [10]

For all elastic collisions we have

$e = \frac{v_2 - v_1}{u_1 - u_2}$

$e = 1 = \frac{v_2 - v_1}{u_1 - u_2}$

$v_2 - v_1 = u - 0$

also by momentum conservation we will have

$m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2$

since two cars are identical so we know that

$m_1 = m_2 = m$

$u + 0 = v_1 + v_2$

now by solving two equations we will have

$v_2 = u$

$v_1 = 0$

so the correct answer must be

It attains the same speed as the first car.

When nuclear fission occurs, some mass is lost. Where does the mass go?

Hoochie [10]

The situation when nuclear fission occurs, some mass is lost is also called the mass defect and as a result the matter turns into energy. If you want to know where the mass does go Albert Einstein will be your helping hand : E = mc^2. Using this formulae you will solve the task and find out the direction of mass.
