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

Hi, can anyone write 5 or 4 paragraph about virus pls I rly need it DO NOT PLAGIARIZE!
Licemer1 [7]
Viruses are microscopic organisms that exist almost everywhere on earth. They can infect animals, plants, fungi, and even bacteria.

Sometimes a virus can cause a disease so deadly that it is fatal. Other viral infections trigger no noticeable reaction.

A virus may also have one effect on one type of organism, but a different effect on another. This explains how a virus that affects a cat may not affect a dog.

Viruses vary in complexity. They consist of genetic material, RNA or DNA, surrounded by a coat of protein, lipid (fat), or glycoprotein. Viruses cannot replicate without a host, so they are classified as parasitic.

They are considered the most abundant biological entity on the planet.

When a car driving up a hill with constant speed: I. its kinetic energy is decreasing. II. its potential energy is constant. III
madam [21]

A car driving up a hill at a constant speed experiences no change in its kinetic energy while it's potential energy increases with increasing height, thus none of the options are correct.

Understanding the concept

Consider a car moving up the hill at a constant speed as shown in the figure below. The following forces act on the car:

  • N is the normal reaction force acting in an upward direction
  • f_s is the static friction force exerted due to friction between the road and the tires of the car
  • f_k is the rolling friction force in the direction opposing that of the  tire
  • mg is the force acting in a downward direction.
  • θ is the angle of inclination.

Here as the car is moving up the hill at a constant speed, the net force exerted on the car is zero. Also, the kinetic energy of the car will not change as its velocity is constant and the potential energy will change with increasing height. Thus, none of the given options are correct.

ra1l [238]

Answer:

a) v = 4.4 m/s

b) F = 400 N

Explanation:

a) ½kx² = ½mv²

v = √(kx²/m)

F = kx

v = √(Fx/m)

v = √(800(0.012) / 0.5) = √19.2 = 4.3817...

b) Fd = ½mv²

F = mv²/2d

F = 0.5(19.2) / (2(0.012) = 400 N
