3 0

Answer:

About 46 billion light years Because space expands so what we didn’t see before is what we could see now. An example could be how everyone thought Pluto was a regular sized planet but once you get a look at the bigger picture and compare it to other thing in space we now know Pluto is a dwarf planet.

When is an object moving in uniform circular motion?

ad-work [718]

When its tangential speed is constant
Although the speed of an object that has a uniform circular motion is constant, its velocity is not constant. Not only that, but it is actually changing constantly.

NemiM [27]

Answer:

The avarage power of the body is 96.898 watts.

Explanation:

We must notice that given definition of power implies a constant consumption of energy, so that we should assume that energy consumption is constant. A Calorie is equal to 4186 joules. If we know that $E = 2000\,Cal$ and $t = 1\,day$ , the power of body, measured in watts, is:

$P = \frac{(2000\,Cal)\cdot \left(4186\,\frac{J}{Cal} \right)}{(1\,day)\cdot \left(24\,\frac{h}{day} \right)\cdot \left(3600\,\frac{s}{h} \right)}$

$P = 96.898\,W$

The avarage power of the body is 96.898 watts.
