In 12 words no symbols or units identify the quantity matchi

In 1-2 words (no symbols or units), identify the quantity matching each description: (a) Rate at which work is done: (b) Energy of motion: (d) Rate at which angular velocity changes: 3. A large steel beam is being raised by a cable. (a) If the tension in the cable is 5670 N, and that force does 34 000 J = 34 kJ of work did the beam rise?

Solution

2. a) rate at which work is done is power. units are watt

b) kinetic energy . unit is Joule

c) Period

d) angular accelration.

3.Beam would rise since the work is done.

4.power =work done /time = 34000/8.9 =3820.22 W
