1 watt = 1 joule per second
1 kilowatt = 1,000 watts
5 kilowatts = 5,000 watts = 5,000 joules per second
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
5 horsepower = 3.73 kilowatts
A 5-watt device gives away 5 joules of energy per second. This is because the unit of watts measures power, which is the rate at which energy is transferred.
A 5 watt light bulb produces 5 joules of energy per second.
5 cm per second is equal to about 0.16404 feet per second.
Per diem Males: 5 x 10-12 Joules Females: 9 x 1015 Joules
When the velocity is tripled to 15 meters per second, the kinetic energy will increase by a factor of 9 (3^2) since kinetic energy is proportional to the square of velocity. So, the kinetic energy will be 225 joules (25 * 9) when the velocity is tripled.
The equivalent of a speed of 5 m2/s2 in joules is 5 joules.
On average, it takes about 6 kWh of electricity to refine one gallon of gasoline. This includes all the processes involved in refining crude oil into gasoline, such as distillation, cracking, and blending.
Velocity of 4 meters per second??? I will assume so. ( need kilograms, so... 5 grams = 0.005 kilograms ) KE = 1/2mV2 KE = 1/2(0.005 kg)(4 m/s)2 = 0.04 Joules =============
kinetic energy = 1/2 * mass *(velocity)^2 = 1/2 * 5 * 2 * 2 = 10 joules
5 meters per second.
