What type of friction is the type of kinetic friction that is difficult to overcome

Dovator [93]

Answer:

Therefore, Static friction is the type of kinetic friction that is difficult to overcome.

Explanation:

Static friction is the frictional force acting between two surfaces which are attempting to move, but are not moving.

Kinetic friction is the frictional force acting between two surfaces which are in motion against each other.

How does losing an electron result in a positive charge?

AlekseyPX

A proton has a positive charge, an electron has a negative charge. Usually, the amount of electrons and protons is the same, but when an electron is lost usually because of radiation or a chemical reaction the resulting amount of electrons/ protons results in a different charge for the atom in general.
When there are more electrons the result it a negative ion, and when there are more protons it is a positive ion.
So, to answer your question: if an electron is lost from a neutral atom and there are more protons than electrons you get a positive charge. Have a good day!

A hovering mosquito is hit by a raindrop that is 50 times as massive and falling at 8.9 m/s , a typical raindrop speed. How fast

Ivahew [28]

Answer:

v = 8.72 m/s

Explanation:

To find the speed of the raindrop joint to the mosquito, you take into account the momentum conservation law for an inelastic collision. Before the collision the total momentum of raindrop and mosquito must be equal to the total momentum of both raindrop and mosquito after the collision.

$m_1v_1+m_2v_2=(m_1+m_2)v$ (1)

v1: speed of the mosquito before the collision= 0 m/s (it is at rest)

v2: speed of the raindrop before the collision = 8.9 m/s

m1: mass of the mosquito

m2: mass of the raindrop = 50m1 (50 time more massive that the mosquito)

v: speed of both raindrop and mosquito after the collision

You solve the equation (1) for v and replace the values of the rest of the parameters:

$v=\frac{m_1v_1+m_2v_2}{m_1+m_2}=\frac{m_1v_1+50m_1v_2}{m_1+50m_1}\\\\v=\frac{0m/s+50(8.9m/s)}{51}=8.72\frac{m}{s}$

hence, after the inelastic collision the speed of the raindrop andmosquito is 8.72 m/s
