1 Watt = 1 joule/second

650 watts = 650 joules/second

(650 J/sec) x (3,600 seconds/1 hour)  =  <em>2,340,000 Joules/hour</em>

Answer:

C) 2,300,000 J

Explanation:

A 120 volt refrigerator uses 650 watts. Calculate how much work is done by the refrigerator in one hour.

A) 9.7 J

B) 39,000 J

C) 2,300,000 J

D) 4,100,000 J

power is the rate at which work is done by a machine.

work done is the product of force and distance,

it is also when energy is expended by a machine

energy can be dissipated by the refrigerator in form of heat

power=650W

time=3600 secs

work done will be 650*3600

2340000.

approximately 2300000J

Explain integration and differentiation in simple method!
Anika [276]
Differentiation in its simplest of terms means breaking something into small parts. On the other hand, integration is taking those really small parts and gluing them in the right order. In short, these terms are the direct opposite or inverses of each other. The term which can tell you how fast you are going at a moment in time at ones current location is called a derivative. The term on the other hand, which can tell you how far you have travelled if you have been keeping track of your location and your time is what an integral is referred to. It is like differentiation only needs knowledge on the local neighbourhood while integration will need the knowledge on a global knowledge.
