Building a new highway destroys habitats and can lead to soil erosion

Because by building a road, your removing land that was once occupied by nature and dividing the animals habitats. With trees being removed, it exposes soil to the climate more, reduces the woods capacity to absorb floods leaving the top layer being carried off, and dried in hotter climates. <span />

Builsinf new highways will mean more nauteal land will be used up, this land will have been used previously by animals who will have made a home there.. AKA. a habitat ... To live there, when new highways are built habitats are destroyed and can lead to soil erosion from less nutrients entering the soil due to it being covered by gravel from the highway

Mass m moves to the right with speed =v along a frictionless horizontal surface and crashes into an equal mass m initially at re

After the collision the magnitude of the momentum of the system is Mv

Given:

mass of 1st object = M

speed of 1st object = v

mass of 2nd object = M

speed of 2nd object = 0

To Find:

magnitude of the momentum after collision

Solution: Product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

Applying conservation of linear momentum

Mv + M(0) = 2MV

Mv = 2MV

V = v/2

So, after collision momentum is

p = 2MV = 2xMxv/2 = Mv

So, after collision momentum is Mv

A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting?

aleksandrvk [35]

It is Tension as the other 3 answer choices would not make sense. Compression would mean you are pressing the rock on both sides or in this case, pushing it into the dirt. It can't be nuclear force as you are pulling out a rock. Air resistance would not make sense either as there is no air involved in the scenario at all.

Newtown third law applies to blank of objects

fomenos

Answer:

All

Explanation:

I'm not sure what you meant but Newton's third law which basically states that every action has an equal and opposite reaction applies to <em>all</em> objects. So I think the answer is all.

A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axi

Marrrta [24]

Answer:

h = 2.64 meters

Explanation:

It is given that,

Mass of one ball, $m_1=3\ kg$

Speed of the first ball, $v_1=20\ m/s$ (upward)

Mass of the other ball, $m_2=2\ kg$

Speed of the other ball, $v_2=-12\ m/s$ (downward)

We know that in an inelastic collision, after the collision, both objects move with one common speed. Let it is given by V. Using the conservation of momentum to find it as :

$V=\dfrac{m_1v_1+m_2v_2}{m_1+m_2}$
