How long does it take mercury to orbit the sun?

5 0

Mercury is the smallest planet of the eight planets and is made up of rock and metal. One year on Mercury is only 88 Earth days. That's how long it takes for Mercury to orbit the sun. Mercury rotates very slowly, so its days are very long. A day on Mercury is 59 Earth days.

That is called the "Revolution Period of a planet" and one year on mercury equals to 88 days as compared to Earth

In short, Your Answer would be 88

Hope this helps!

A 0.140 kg baseball is thrown horizontally with a velocity of 28.9 m/s. It is struck with a constant horizontal force that lasts

Viefleur [7K]

Answer:

4987N

Explanation:

Step 1:

Data obtained from the question include:

Mass (m) = 0.140 kg

Initial velocity (U) = 28.9 m/s

Time (t) = 1.85 ms = 1.85x10^-3s

Final velocity (V) = 37.0 m/s

Force (F) =?

Step 2:

Determination of the magnitude of the horizontal force applied. This can be obtained by applying the formula:

F = m(V + U) /t

F = 0.140(37+ 28.9) /1.85x10^-3

F = 9.226/1.85x10^-3

F = 4987N

Therefore, the magnitude of the horizontal force applied is 4987N

Answer:

748 treats.

Explanation:

If the trainer gives out 34 treats and gave them out for 22 shows, then to find the total you need to multiply 34 by 22, or (a longer but more simple way) add 34, 22 times.

Could someone please tell me what I'm doing wrong?

7nadin3 [17]

Answer:

M1 = 16.9 mA

M2 = 0 A

Explanation:

As the ratio of the two sets of series resistors is almost exactly identical, there is no voltage difference across M2 to cause current flow

269/(269 + 439) = 0.3799...

500/(500 + 815) = 0.38022

M2 = 0

M1 sees only the current flowing through the far left resistors in series

A = V/R = 12/(269 + 439) = 0.016949... ≈ 16.9 mA
