Some light gets through grape jelly, but not much.
<span>If you were to shine a bright light at the jar . . .

-- A little bit of the light would reflect off of the jar, and never
get as far as the jelly.  The rest of the light would pass through
the glass and hit the jelly. 

-- Some of the light that hit the jelly would reflect off of it, and
never actually enter the jelly.  The part that reflected off of it
would be mostly the purple wavelengths. They </span>would go back
out through the jar, into the kitchen.
<span>The rest of the light would enter the jelly.   

-- Of the light that entered the jelly, MOST of it would be absorbed
by the jelly and never seen again.  This would happen to all of the
wavelengths of light EXCEPT purple, although SOME purple light
would also be absorbed.

-- At the end of the jelly, when the light reached the other side of the
jar, there would be very little of it left, and that little bit would be almost
all purple wavelengths.  That little bit of light would come out the other
side of the jar into the kitchen.  If anybody was standing there and some
of the light happened to go into his eyes, he would say "Oh look !  I can
SEE that the stuff in the jar is dark purple!".</span>

At a given point in its orbit, the moon is 2.4 x 10^5 miles from earth. How long does it take light from a source on earth to re
Mice21 [21]

Answer:

Total time= 2.56 s

Explanation:

Given that

Distance = 2.4\times 10^5\ miles

So distance = 386242560 m

Velocity of light

C= 3\times 10^8\ m/s

We know that

Distance = velocity x time

Now by putting then values

time=\frac{386242560}{3\times 10^8}

t=1.28 s

So the total time = 2 x 1.28

total time= 2.56 s

Calculate the normal force pushing up from the table in each example 8 kg
garik1379 [7]

The correct answer to the question is: 78.4 N.

EXPLANATION:

As per the question, the mass of the object is given as m = 8 Kg.

We are asked to calculate the normal force of the object.

The object is resting on the table.

Hence, the object pushes the table downward with a force equal to it's weight.

The table, in turn, pushes the object with the same force as given by the object, but in the upward direction.

The force given by the table on the object is known as the normal reaction of the object which acts perpendicular to the surface of the object.

Hence, the normal reaction is equal to the weight of the body.

The weight of a body is the product of it's mass with acceleration due to gravity.

So, the weight of 8 Kg object is calculated as -

Weight = mg

= 8 × 9.8 N.

= 78.4 N.

Here, g is known as acceleration due to gravity.

Hence, the normal force pushing up from the table is 78.4 N.

The forces acting on a child sitting in a seat are described by the free-body diagram shown. What is the net force acting on the
r-ruslan [8.4K]

The net force is 0 N.

To find the total net force, all you need to do is add the forces.

So 100 + -100 = 0

Most of these questions are trick questions, but if you know Newton's laws of forces, then you should know that all forces should cancel out with each other.

Hope this helps!!!

Explain The Big Bang Theory in 100 Words​
mixer [17]

Answer:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
