Answer:
The amount of energy that would be released is equal to 4182 Joules.
Explanation:
Total amount of coke = 2 kg = 2000 g
1 calorie per gram is equal to 4.184 Joules of energy
4.184 J/gC*2000g = 8368 J
1 food calorie is roughly equal to 4186 J
8368 - 4186
Therefore, the amount of energy that would be released is equal to 4182 Joules.

That would be true because a solid object can cast a shadow
Answer:
Explanation:
From the law of conservation of energy
Energy lost by the spring, W=Kinetic energy gained, KE+Potential energy gained, PE+Work done by friction, Fr
The required distance from A to B is
Answer:
Power = 124.50 W
Explanation:
Given that:
The Sound intensity of a speaker output is 102 dB
and the distance r = 25 m
For the intensity of sound,
where;
the threshold of hearing
I = 0.01585 W/m²
If we recall, we know remember that ;
Power = Intensity × A
rea
Power = 0.01585 W/m² × 4 × 3.142 × (25 m)²
Power = 124.50 W
