5 0

Answer:

It takes 266 seconds to melt the ice.

Explanation:

Given data

  • Power of the microwave oven (P): 125 Watt
  • Heat supplied to the ice (Q): 33,200 Joule
  • Time for the melting (t): to be determined

In order to determine the time required to melt the ice, we can use the following expression.

P = Q/t

t = Q / P = 33,200 J/ 125 W = 266 s

It takes 266 seconds to melt the ice.

A person is just as likely to become dehydrated in the cold as in the heat. Please select the best answer from the choices provi
alexdok [17]
The answer would be A) TRUE because we as humans can be dehydrated easily just by working out in sun or working out in the cold winter, that's how our body burns fat and calories, but it also burns our eyes since sweat has salt in it, and dehydrated means to run out of water for us, like not enough water, but yes to the answer its T.

The diagram shows a 225 N load attached to a moveable pulley.What amount of force is needed to lift the load?
hram777 [196]
I'm happy to know that the diagram shows how it's all set up.
If I could see the diagram, then I could probably do a much
better job with an answer.  As it is ... 'flying blind' as it were ...
I'm going to wing it and hope it's somewhat helpful.

If the pulley is movable, then I'm picturing one end of the rope
tied to a hook in the ceiling, then the rope passing down through
the pulley, then back up, and you lifting the free end of the rope.

A very useful rule about movable and combination pulleys is:
the force needed to lift the load is

            (the weight of the load)
divided by
            (the number of strands of rope supporting the load) .

With the setup as I described it, there are 2 strands of rope
supporting the load ... one on each side of the pulley.  So the
force needed to lift the load is

                                 (250 N) / 2  =  125 N .
