Answer:
Final energy will be 40 KJ
Explanation:
We have given that 30 KJ of the heat is transferred to the water
So
And 5 KJ of heat is lost to the surrounding air
So
So total heat
The paddle-wheel work amounts to 5000 N -m
So work done W = -5 KJ ( as work is done by the paddle wheel )
We know that
We have given initial kinetic energy = 10 KJ
So
So final energy = 30+10 =40 KJ

When two players are running full speed at each other on a football field they build up their momentum
Many animals rely on their sense to alert them about changes in temperature. <span>Some ways that animals adapt for the seasons include migration, hibernation and physical changes that help them survive the differences in the weather. Hope this helps.</span>
Answer:
As the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Explanation:
As the object is moving towards the lens then in that case first the image will form between the focus and double the distance of focus.
So here the image is diminished
now when the object is at large distance from from lens then its image will form at focus and it is of very small size
Now as the object comes closer to the lens till the object distance is 2F the image size will increase but smaller then object size
Now when object is between F and 2F then the image size will be more than object size and it will increase to infinite magnification
So overall we can say that as the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
