Mainly because he was Johnny Carson's advisor and consultant
on space, astronomy, and science in general, and he appeared

Answer:
6KW
Explanation:
The computation is shown below:
We know that
Work done= m ×g× h
Here
W= 300×10×10
= 30000 J
= 30 KJ
And
Power= Work done ÷time taken
P = 30000 ÷ 5
= 6000W
= 6KW
The above represent the answer
Answer:
This is important because in the case of the potassium atom, the outermost electrons will be attracted by the nucleus more. In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons.
Explanation:
According to Newton's 2nd Law of Motion, if a constant force acts on an object, the object will accelerate.
According to Newton’s law of universal gravitation, the gravitational attraction between the Earth and an object causes a constant force to act on the object.
So, because of that force, Falling objects accelerate as they approach the ground. <em> (B)</em>
