Time = distance / speed
Time = (4,800 meters) / (3 x 10⁸ m/s)
<em>Time = 0.000016 second</em>
This number is not one of the choices on the list. My hunch is that you copied the distance wrong.
If the estimated distance to the star is actually 4.8 x 10¹⁵ km, instead of 4.8 km, then the answer would be close to 500 years <em>(B)</em>.
There's no way a star can be "4.8 km away from the Earth". You can <em>walk</em> that far in about an hour, and passenger jet airplanes fly <em>twice</em> as far as that away from the Earth !
A falling raindrop
Kinetic energy and potential energy are both applied when a body or object is falling.
Speed is distance divided by time (s = d/t)
Explanation:
Mass : -
1. It is the amount of mass present in an object.
2. SI unit : Kilograms ( kg )
3. Relation between Mass and Weight is W = mg.
Weight : -
1. It is the force with which it is attracted towards the centre of the earth.
2. SI unit : Newton ( N )
3. Relation between Mass and Weight is W = mg.
Answer:6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen
