(b) The diagram shows the energy transformations produced by a TV.

(1)
Which are the useful energy outputs?
(1)
(ii)
Use the information in the diagram to calculate the efficiency of the TV.
Write down the equation you use, and then show clearly how you work out
your answer.

iii) what eventually happenes to the useful energy transferred by the tv?

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?
