Why is mass movement more common after a heavy rainfall?

Physics
1 answer:
lara31 [8.8K]3 years ago

A heavy rainfall will fix two things to rocks and soil. First the extra water just makes them denser. The additional weight may be just sufficient to let things to move. Second, the rainwater becomes into all of the openings of the soil or round the rocks. This can perform as an emollient to assist the particles or the rocks start touching down the slope in the development of mass wasting.

hoa [83]

Explanation:

A substance with a short , medium, free path has improved electron flow resistance and a higher electrical resistance . Heat applications impose more molecular chaos on all materials and shorten the track further, increasing resistance of most materials. So, just refresh the material to expand the course. In certain materials, when cooled to the minimum temperature, the conductivity is substantially increased.

A 22.8 kg rocking chair begins to slide across the carpet when the push reaches 57.0 N. What is the coefficient of static fricti
vfiekz [6]

Answer:

0.255

Explanation:

The following data were obtained from the question:

Force (F) = 57 N

Mass (m) = 22.8 Kg

Coefficient of static friction (µ) =...?

Next, we shall determine the normal reaction (R). This is illustrated below:

Mass (m) = 22.8 Kg

Acceleration due to gravity (g) = 9.8 m/s²

Normal reaction (R) =?

R = mg

R = 22.8 x 9.8

R = 223.44 N

Finally, we can obtain the coefficient of static friction (µ) as follow:

Force (F) = 57 N

Normal reaction (R) = 223.44 N

Coefficient of static friction (µ) =...?

F = µR

57 = µ x 223.44

Divide both side by 223.44

µ = 57/223.44

µ = 0.255

Therefore, the coefficient of static friction (µ) is 0.255.

a 4050 N sled is being pushed with a force of 575 N. If it encounters a frictional force of 385 N… determine the net force
creativ13 [48]

According to the solving the net force is:

= 3,860.

<h3>Why is net force important?</h3>

The net force is the total of all the forces operating on an object, according to its definition. Mass can be accelerated by net force. Whether a body is at rest or in motion, another force is at work on it. When a system has a lot of forces acting on it, the phrase "net force" is employed.

<h3>What's the net force equation?</h3>

When a body is moving and multiple forces, such as the normal force, frictional force, and gravitational force, are acting on it, the combined effect is known as net force. As a result, is the net force formula. FNet equals Fa, Fg, Ff, and FN.

<h3>According to the given data:</h3>

4050 N sled

force of 575 N.

encounters a frictional force of 385 N

So the net force will be:

(Net)F = F₁ + F₂ + F₃

So,

(Net)F = F₁ + F₂ - F₃(frictional force)

(Net)F = 4050 + 385 - 575

= 3,860

According to the solving the net force is:

= 3,860.
