Increase in the object's potential energy = (force) x (distance) = (200) x (4) = 800 newton-meters = 800 joulesPower = (800 joules) / (4 seconds) = 200 joules per second = 200 watts

The watt is a rate of delivery or use of energy (1 Joule per second) Anything called watts per day means an increase in power per day. (100 watts first day, 200 watts second day, 300 watts third day etc). I'm sure you don't mean that. Direct ("normal" ) sunlight that falls on a square metre is up to about 100 Watts so you'll never get more power from that even with 100% efficiency. Consult the brochures. Probably a few tens of watts per square meter. Energy per day is watts x time-of-sunlight (direct, near 90 degrees). Which will be Joules. 3600x1000 Joules equal 1 Kilowatt-hour, sometimes called "1 unit".
1,000 J
According to the formula, Work done = Force . Displacement So, 200(10) 2000 joules. Hence, the work done by the person will be 2000 joules.
200,000-150,000= 50,000 25 %
1 joule = 1 newton-meter 800 joules = 800 newton-meters = (200 newtons) x ('H' meters) H = 800 N-m / 200 N = 4 meters
200 joules of any other type of energy can be converted to 200 joules of heat.
The AED output is in joules (J); an energy output. Energy is an Amp Ohm divided by time. Although AED's may vary on their output, depending on numerous criteria, some AED's will shock at 200J, then 300J, then 360J.

2000 joules
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.
Time= 1800
850 joules = 200 calories. 850 joules = 200 calories.
A small coffee grinder 100-200 watts.
200 joules
A small shredder 100-200 watts.
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
