Answer:
through nuclear fusion
Explanation:
The burning of the sun is not chemical combustion. It is nuclear fusion. This combustion releases energy which we experience as the heat and light given off by the flame.
Answer:
The bird's speed immediately after swallowing is 6.17 m/s.
Explanation:
Given that,
Mass of the bird, m = 270 g = 0.27 kg
Initial speed of the bird, u = 5 m/s
Mass of the insect, m' = 11 g = 0.011 kg
Initial speed of the insect, u' = 35 m/s
We need to find the bird's speed immediately after swallowing. Let it is given by V. Using the conservation of momentum as :
So, the bird's speed immediately after swallowing is 6.17 m/s.
Answer:
Explanation:
Properties of Projectile Motion. Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola.
The number of protons in any element can never change.
