Why is it important to know the velocity of an object instead of just speed?

1 answer:

Velocity helps measure the rate at which an object changes it's position in a given direction. If you were measuring a tornado, for example, you would want to know both speed and velocity to predict where as well as how fast it will travel.

Answer:

The correct answers are:

• Softer, porous, or more permeable rocks weather faster than harder rocks.

• Rocks in warmer climates weather faster than rocks in colder climates.

• The more water present, the faster the rate of weathering.

Explanation:

Weathering is the process through which the surface minerals of rock are broken down and loosened. This occurs through the action of extreme temperatures, rainwater and biological activity.

If the length of a string increases 2 times but the mass of the string remains constant, the new density of the string will equa

Genrish500 [490]

If the length of a string increases 2 times but the mass of the string remains constant, the original density will be multiplied by a factor mathematically given as

v=1.414 times

<h3>Will the new density of the string equal the original density multiplied by what factor?</h3>

Generally, the equation for the volume is mathematically given as

v = sqt(TL/m)

Where

density = mass/length

Therefore

$v2/v1 = \sqrt{L2/L1}$

$v2/v1 = \sqrt{2}$

In conclusion,v ratio will give us

v=1.414 times
