Alfred Wegner first proposed the idea that all the seven continents were once one super continent called "Pangea". Everyone considered his idea as a joke until he proved his theory with evidence of matching fossils, matching mountain ranges, and how all the continents fit together like puzzle pieces. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.

1200kg car speeds up from 2 m/s to 6 m/s. How many times greater is the car's kinetic
Bezzdna [24]

Answer:

9 times as great

Explanation:

KE = 1/2mv²

  1. 1/2(1200)(2)² = 2,400 J
  2. 1/2(1200)(6)² = 21,600 J

21,600 / 2,400 = 9

What will happen to the 0.1 N force if one charges is increased by a factor of 3?
AleksandrR [38]

Answer:

Explanation:

Force between two charges is given by the following expression

F = \frac{KQ_1Q_2}{d^2}  Q₁ and Q₂ are two charges and d is distance between two.

.1 = \frac{KQ_1Q_2}{d^2}

If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.

Force F = .3 N

If charge becomes one fourth , force also becomes one fourth .

F= \frac{.1}{4}

= .025 N.

When you look at a white light bulb through red sunglasses, why does the light look red to your eyes? What happened to all the o
Lelu [443]

Answer:

The answer is explained below in explanation

Explanation:

Whenever light falls on a colored surface, that color of light is reflected by the surface and all the other colors are absorbed. That is a black body appears black in all lights, because it absorbs every color and a white surface appears to be of the color of the light shone upon it because it is the mixture of all colors of light and reflects every color. The eyes only see the reflected light colors. The absorbed colors are not apparent to the eyes.

<u>Hence, when the white bulb is seen through red sunglasses, it does look like red to our eyes, while all the other colors are absorbed by the sun glasses.</u>
