To solve this problem we will apply the definition of Power and Speed. In turn, we will consider that one gram of carbohydrate, according to numerous scientific studies, contributes around 17kJ of energy. Therefore, if this were true, the total energy of 26 grams would be
Power can be described as the amount of energy applied at a given time, that is,
The speed is described as the distance traveled in a certain time, and its units in international system is m / s, converting and replacing we will have
Now,
The distance is,
Therefore the distance walked is 1610.08m
Answer:
The amount of energy needed to raise the temperature of the cylinder by 25 °C is 23.3 KJ of heat.
Explanation:
The step by step calculation can be found in the attachment below. Thank you.
the answer is definitely A.
<span>Work: W = Fd. 50(distance) multiplied by 90(force) would equal 4500 J or, answer D</span>
Answer:
It is easier to scale the voltage of AC from high to low and low to high than with DC
Explanation:
typically power is used far away from the place where it's generated so to ensure that transmission losses( copper losses) are minimized voltage has to be stepped up during transmission..but due to the fact that most house hold equipment requires low voltage levels it has to be stepped down once it reaches a household/ domestic load...it's easier to do this for Ac than for DC.
