Withe light becomes a spectrum of seven colored lights after passing through a prism
Fiesta28 [93]

True. The 7 colors, also called a rainbow, are red, orange, yellow, green, blue, indigo, and violet. This rainbow is formed because the prism bends the white light and spreads it out into the colors it was made of. If there is more you were looking for, comment here.

A sled is accelerating at 2 m/s2 because it is being pushed on ice by Jenny. Tommy then jumps on the sled (he has the same mass
Radda [10]

Answer:

The acceleration of the total mass decreases by half (1/2)

Explanation:

Given;

acceleration of sled = 2 m/s²

From Newton's second law of motion, F = ma

⇒m = F/a

F is the force applied by Jenny

This force applied by Jenny should be the same, after Tommy jumps on the sled, but the acceleration will change.

F = m₁a₁ = m₂a₂

Since m₂ = 2m₁, then we calculate a₂

m₁a₁ = 2m₁a₂

a₂ = a₁/2

Therefore,The acceleration of the total mass decreases by half.

C.<br>Difference between<br>D) solar energy and fossil fuel energy​
jonny [76]

hii

here's your answer

Fossil fuel use is integrated into the fabric of American society. Natural gas, petroleum and coal together accounted for more than 80 percent of energy use in the United States in 2012. Meanwhile, more than 5 gigawatts of solar power capacity was scheduled to come online in 2013 -- about as much capacity as was added for coal plants over a nearly 20-year span. The characteristics of solar power and fossil fuels drive the desire to adopt a particular energy source for a specific application, and they also limit the possible applications of a specific energy source.
