<span>When placing each domino upright, potential energy is conserved in that domino. When kinetic energy is initially added into the first domino, this energy converts the next domino's potential energy to kinetic energy, which is transferred to the next domino afterwards. Hope this helps ;3</span>
Answer:
60N
Explanation:
Given parameters:
Combined mass = 50kg
Acceleration = 1.2m/s²
Unknown:
Force to propel = ?
Solution:
From Newton's second law of motion, we know that;
Force = mass x acceleration
So;
Force = 50 x 1.2 = 60N
i think it’s B. sorry if i’m wrong
Hello
You expect to see:
1) A solar eclipse, when the earth is between the sun and the moon: the shadow of the earth is projected on the moon surface, and the sun will appear dark
2) An "earth eclipse", when the moon is between the sun and the earth: the shadow of the moon is projected on the earth surface, therefore the earth will appear dark.
