How do earthquakes affect earths surface?

Physics
1 answer:
ivanzaharov [21]3 years ago
4 0
Some of the reasons that can cause can earthquake are volcanic eruptions, the grinding of tectonic plates beneath the earth's crust and violent explosions which can be artificially induced as well. No matter what the reason is, earthquakes affect the environment and earth's surface. Noticeable cracks have formed on the earth's surface after earthquakes. If the tremors are violent, it can result in the destruction of landscapes. The mountains become prone to land sliding. the glacier's become a threat because of fear of avalanches. tsunamis which are earthquakes in the ocean bed can cause heavy flooding which causes water to cross all boundaries and shores and flood entire cities. Earthquakes caused by volcanoes can result in the spewing of so much lava that it may spill everywhere and cool changing the surface of the earth geologically as well as the ash causing aerial pollution.

A 50.0 kg person is walking horizontally with constant acceleration of 0.25 m/s² inside an elevator. The elevator is also accele
Alexxandr [17]

Answer:

The acceleration is in 2 D as in between east and south.

Explanation:

mass, m = 50 kg

acceleration, a = 0.25 m/s^2 horizontal

acceleration of elevator, a' = 1 m/s^2 downwards

When a person on the ground the resultant acceleration of the person with respect to the ground is between east and south direction so the path os parabolic in nature. It graph is shown below:

Transverse waves travel with a speed of 20.0 m/s on a string under a tension of 6.00 N. What tension is required for a wave spee
marta [7]

Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.

<h3>What is the required tension?</h3>

Given the initial tension and speed, the tension that is required can be found by the formula:

= Initial tension x (Required speed / Initial speed)²

Solving gives:

= 6 x (30 / 20)²

= 6 x 9/4

= 13.5 N

In conclusion, the tension required is 13.5N.

A car of mass 1000 kg travels around a level curve of radius 40 m. If the maximum frictional force that can be exerted upon the
Tasya [4]

Answer:

The car can travel V=19.8m/s without spinning out

Explanation:

Given that

Mass of the car m=1000kg

Radius of curve r =40m

frictional force R=7000N

Coefficient of friction u=?

We know that F=uR

But F=ma

F=1000*9.81

F=9810N

Therefore u=F/R

u=9810/7000

u=1.40

For the car to travel without spinning out we

Equate it centripetal force formula to frictional force formula

F=mv²/r

F=ur

hence mv²/r=uR

Making velocity subject of formula we have v²=u*r*R/m

V²=(1.4*40*7000)/1000

V²=392

V=√ 392

V=19.8m/s
