The Kepler laws of planetary motion are:

1) The planets revolve around the Sun following elliptical orbits, in which the Sun occupies one of the two focii

2) A line segment connecting the Sun with the center of each planet sweeps out equal areas in equal intervals of time --> this means that the speed of the planet changes according to its distance from the Sun: the closer to the Sun, the faster the planet

3) The square of the orbital period of the planets is proportional to the cube of the semi-major axis of the orbit. In formula

\frac{T^2}{r^3} = const.

and the constant in the equation has the same value for every planet orbiting around the Sun.

Nadya [2.5K]
Power=Work/Time
The work done is the energy required to lift the box, fighting the force of gravity. So, Work=Potential energy of the box at 10 meters.

W=PE=mgh=(60)(9.8)(10)=5880J
Finally,
P=W/T=(5880)/(5)=1176Watt

So the answer is 1176 Watts

As the punnet chart was not given with the question, the question is searched and found online which is as attached herewith.

As seen from the punned table the column head has two capital H which indicate that the cat is a black cat.

White the row heads indicate a Capital and a small h thus this is a spotted cat

Thus the punnet chart indicate the cross between a black cat and a spotted cat.
