Answer:

0.0026 m/s²    

Explanation:

Centripetal acceleration is given as follows:

a=\frac{v^2}{r}\\where, v =\frac{2\pi r}{T}

a=\frac{(\frac{2\pi r}{T})^2}{r}=\frac{4\pi^2r}{T^2}

T=28.0 days\times 24hours\times 3600 s= 2.4\times10^6s

r=240000 mi = 384.4\times 10^6 m

Substitute the values:

a=\frac{4\pi^2 \times 384.4\times10^6}{(2.4\times10^6)^2}=0.0026m/s^2

PLEASE HELP ASAP!! What are 3 types of forces acting on your marshmallow (or other flying object) when it impacts it’s target? C
Alekssandra [29.7K]
•Every action has an equal and opposite reaction (the object is putting force on the target, and the target is putting an equal amount of force back)
•Am object in motion (the object) will stay in motion unless an outside force acts upon it (the Target)

And as for the third one I really don’t know, those seem to be the only two, I’m sorry. I did what a could, Hope it kinda helps :)

How does the law of inertia relate to how the planets in our solar system revolve around the sun?
Alekssandra [29.7K]

Answer:

The law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.

Explanation:

Law of inertia states that a body at rest or uniform motion will continue to be at rest or uniform motion unless it is acted upon by an external force.

The gravitational force keeps the planets revolving round the sun in a uniform motion, this will continue till infinity unless equal and opposite force acts on our planets.

Therefore, the law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.
