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

How many watts could a solar panel generate in one day?
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".
What is the change in the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?
1,000 J
A worker applies a 200-n force to a create that he pushes 10m how much work was done?
According to the formula, Work done = Force . Displacement So, 200(10) 2000 joules. Hence, the work done by the person will be 2000 joules.
What is the efficiency of a street cleaners engine when the heat input is 200 000 joules and the waste heat is 150 000 joules?
200,000-150,000= 50,000 25 %
How high is a shelf if 800 joules of work is done lifting a 200 newton box?
1 joule = 1 newton-meter 800 joules = 800 newton-meters = (200 newtons) x ('H' meters) H = 800 N-m / 200 N = 4 meters
How many amps in 200 joules?
200 joules of any other type of energy can be converted to 200 joules of heat.
How many watts are in defibrillator?
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.
How many joules should a defribrillator be placed at?
200
How many joules of work would be accomplished if you move a 200 kg slug 10 meters?
2000 joules
How dou you convert joules to watts?
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.
Nisha's vacuum cleaner has a power rating of 200 watts. If the vacuum cleaner does 360000 joules of work. How long did Nisha spend vacuuming?
Time= 1800
What is a material which contains 850 Joules?
850 joules = 200 calories. 850 joules = 200 calories.
How many watts does grinder consume?
A small coffee grinder 100-200 watts.
If you exert 200 joules in peddling a bicycle on level ground what is the work output?
200 joules
How many watts does it take to run a paper shredder?
A small shredder 100-200 watts.
How many volts are 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
How many watts does a small car need?
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
