Answer:

Erosion is the constant gnawing, erosion and degradation that occurs on the earth's surface. That is, when external geological forces, such as rivers, glaciers, flowing water, winds or waves, carry along and gnaw rock particles and move material from one location on the earth's surface to another.

The rate of erosion is influenced by climate, topography, the extent of vegetation cover and the properties of the loads. Deforestation and cultivation methods that change the soil structure, for example, make the soil harder so that it does not drain away water so quickly, can increase the erosion rate and cause major damage. It is estimated that 30-40 billion tonnes of land is eroded each year from the world's agricultural areas.

A spring has a period of 1 s when a 0.200 kg mass hung from the end of it. If the mass at the end is changed to 0.100 kg, will t

shutvik [7]

When the mass of the spring changed from 0.2kg to 0.1kg, the time period changed from 1 sec to 0.5 seconds

<u>Explanation:</u>

Given-

Mass, m1 = 0.2kg

Time period, T1 = 1s

m2 = 0.1 kg

T2 = ?

We know,

$T = 2\pi \sqrt{\frac{m}{k} }$

where,

T = Time period

m = mass

k = spring constant

From the equation, we can see that T is directly proportion to the square root of mass, m

T ∝ √m

So,

If m1 = 0.2kg , T1 = 1s and m2 = 0.1kg

The T2 would be:

$\frac{T1}{T2} = \frac{m1}{m2} \\\\\frac{1}{T2} = \frac{0.2}{0.1} \\$

$T2 = \frac{1}{2} \\\\T2 = 0.5sec$

Therefore, when the mass of the spring changed from 0.2kg to 0.1kg, the time period changed from 1 sec to 0.5 seconds

Two rocket ships named Alpha and Beta are at rest in space. Alpha fires its engines, and accelerates because of the thrust (or f

maria [59]

Answer:

Explanation:

Given

Beta rocket has twice the mass of Alpha engine

suppose alpha has a mass of m so beta has 2 m mass

Thrust force on alpha is F

thrust force on beta is 2 F

Acceleration of alpha $a_{alpha}=\frac{F}{m}$

Acceleration of beat $a_{beta}=\frac{2F}{2m}=\frac{F}{m}$

Therefore acceleration of alpha and beta is same

How could you increase the gravitational potential energy between yourself and the Earth?

pogonyaev

Answer :

Gravitational Potential Energy, GPE = mgh

Where m is your mass in kg, g is acceleration due to gravity = 9.8 m/s², and h is the height in m.

The only value that be controlled here is the height h. The mass is constant, and acceleration due to gravity at that place is constant.

But h can be varied.

Hence to increase the gravitational potential energy between yourself and Earth is to increase the height h.

This can be done by climbing up a table, or climbing up a building through the stairs, or by using a lift.
