What happens to a reflection of light that has struck a surface?A) It bounces off.
B) It becomes absorbed.
C) It gets transmitted.
D) It gains energy.

Answers

Answer:

A) It bounces off.

Explanation:

Bouncing back of light into the same medium is known as reflection of light

As per law of reflection we know that light incident on the surface at a given angle with respect to the normal then the angle of reflected light with the normal will be same

angle of incidence of light = angle of reflection of light

Also we know that incident light, reflected light and normal always lie in the same plane

So we can say that here correct answer will be

A) It bounces off.

Answer:

The answer is A) It bounces off

Explanation:

Refraction bends and Reflection bounces off. (I just took the test).

When traveling at top speed, a roller coaster train with a mass of12,000 kg has a velocity of 30 m/s. The kinetic energy of the train at top speed is

Answers

Answer:

The kinetic energy of the train at top speed is 5,400,000 J

Explanation:

Kinetic Energy

It's the capacity that an object has to do work in virtue of its velocity. If we use UI units for the mass and velocity, the kinetic energy is expressed in Joules, or Nw.m or Kg.m^2/sec^2. It can be computed with the formula

\displaystyle K=(mv^2)/(2)

The roller coaster train has a mass of 12,000 kg and a velocity of 30 m/s. Replacing those values in the formula, we have:

\displaystyle K=(12,000\ 30^2)/(2)

\displaystyle K=(12,000\ 900)/(2)

\displaystyle K=5,400,000\ J

Answer: the first answer is 5,400,000 the second one is 46

A small child has a wagon with a mass of 10 kilograms. The child pulls on the wagon with a force of 2 Newtons. What is the acceleration of the wagon? 

Answers

We know that Force (F) is equal to mass (m) times the acceleration (a)
Mathematically,
F=m.a

Here:
m=10 and F=2
by solving for a we get a = 0.2 meters per second squared.
the answer is 0.2 meter per second squared.

a classmate states that continental drift could not be possible because it would take far too much force to move tectonic plates. describe the hypothesis scientists use to explain the movement of tectonic plates. which hypothesis do money scientist things may explain the great force needed to move plates

Answers

Seafloor Spreading is how the plates move. It is a process in which new oceanic crust (ocean floor) is created from the hot magma that comes to the surface. The magma is cooled by the water. The new floor pushes outward and moves the old floor. This is the force that causes the plates to shift. Harry Hess came up with this theory. John Tuzo Wilson combined Alfred Wegener's theory of continental drift and Harry Hess's theory of seafloor spreading to create a reasonable explanation for how the plates could have moved then created his own theory of plate tectonics.
