Speed is a derivation of energy (thats what my science teacher said)
Work can be represented by Wd (Work done) or Ew (Energy, work). Since it is a form of energy, it is measured in joules
When a candle burns, you can't hear the flame, and you can't light a light-bulb with it, so you know that there's no sound energy or electrical energy coming from it.
However, if you've ever actually been around a candle while it's in the act of burning, you may have noticed that you can SEE the flame, and if you put your hand close enough to it, you can FEEL the flame and even burn yourself in it. These observations indicate that while the candle is burning, the chemical energy in it is being converted to light energy and heat energy. (choice-C)
Answer:No
Explanation:
No
As the train is accelerating so train velocity will be more as compared to the ball and thus will cover more distance as compared to the ball.
When the ball is thrown upward with some velocity, it also possesses the train velocity at the time of throwing but as time passes velocity of train increases due to acceleration of the train. This causes the ball to fall behind the point of launch.
