Well, darling, the energy weight of 100 joules per second is simply 100 watts. It's like asking how many slices of cheesecake you can eat in a minute - one slice per minute, just like one watt is one joule per second. Easy peasy, lemon squeezy!

The energy weight of 100 joules per second is equivalent to a power output of 100 watts. This is because power, measured in watts, is the rate at which energy is transferred or converted. Therefore, if 100 joules of energy is being transferred or converted every second, the power output is 100 watts.
Oh, dude, that's just a fancy way of saying 100 watts. It's like the unit of power, you know, how much energy is used or produced in a second. So, yeah, 100 joules per second is just 100 watts. Cool, right?
Well, isn't that just a lovely question? When we talk about energy weight, we're actually referring to power, which is the rate at which energy is transferred or converted. So, if you have 100 joules per second, that means you have a power output of 100 watts. Just imagine all that energy flowing like a gentle stream, bringing brightness and warmth to everything it touches.
100 Joules / sec = 100 Watts
Example of 100 Watts:
(Taking g as 10 (m/s)/s)
Lift 10 kg 1 metre in 1 second
Power = energy change / time = mgh / 1 = 100 / 1 = 100 Watts
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
GPE = mgh = (mg)*h = 200*100 = 20,000 Joules.
average.. is about 100.
Answer:87.62 %Solution:given: Second exam weight = 66%then: overall weight = 100% this is conclusion from the question.the first exam weight = 100-66= 34%Final result = weighted average =(first exam result * weight of first exam + second exam reuslt * weight of second exam) / Overall weight= (83*34+90*66)/100=(2822+5940)/100= 8762/100= 87.62%---More information about weighted mean:http://en.wikipedia.org/wiki/Weighted_mean
