Answer:

The car take the time is 3.0 sec

Explanation:

Given that,

Speed = 24 m/s

Acceleration = -8.0 m/s²

We need to calculate the time

Using equation of motion

v = u+at

Where, v = final velocity

u = initial velocity

a = acceleration

t = time

Put the value into the formula

0=24-8.0\times t

t =\dfrac{24}{8.0}

t = 3.0\ sec

Hence, The car take the time is 3.0 sec.

Use this formula:

final speed = initial speed + acceleration * time

0 = 24 - 8*t, t = 3 s! The answer is 3 seconds

The process by which land remove surface materials is called
Citrus2011 [14]

Answer:

Deflation

Explanation:

The process by which wind removes surface materials is called deflation.

Deflation is a process by which wind erodes the Earth's exterior and the regions which experience severe erosion are called deflation zones.

deflation originates by the erosive force of a wind that removes the loosened area and this process is facilitated by a dry climate and a loss of vegetative cover that helps to lose the sediment.

deflation is common in the arid regions.

What is the role of gravity when it comes to changing the velocity of objects?
Alex787 [66]

Gravity is the attraction of every body to every other body due to the masses of each body. The larger the mass, the greater the force. It also depends on the distances: the closer the bodies, the greater the force. Gravity is directed toward the center of a body, and the distance is measured from the center.

When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Help<br><br><br> What are energy and work
mylen [45]

Answer:

<em>In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.</em>

What are the characteristics of Earth’s lithosphere and how does the lithosphere play a role in plate tectonics?
pashok25 [27]
The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the lithosphere are still considered elastic, they are not viscous
