It takes approximately 88 Earth days for Mercury to orbit the sun.
Hope I helped, sorry if I'm wrong ouo.

No, aluminum has a density near 2.7 g/cm^3
<span>7.8 g/cm^3 is near the density of iron (or in the case of a fork, steel).
this is it

Answer:
461.88 N
Explanation:
The swing is in static equilibrium. T is the tension in the string. Refer to the attached figure.
In the vertical direction:
![T cos 30^o= mg = 800 N\\ \Rightarrow T = 923.76 N](https://tex.z-dn.net/?f=%20T%20cos%2030%5Eo%3D%20mg%20%3D%20800%20N%5C%5C%20%5CRightarrow%20T%20%3D%20923.76%20N)
In the horizontal direction:
![F= T sin 30^o\\ \Rightarrow F = (923.76 \times sin 30^o) N=461.88 N](https://tex.z-dn.net/?f=%20F%3D%20T%20sin%2030%5Eo%5C%5C%20%5CRightarrow%20F%20%3D%20%28923.76%20%5Ctimes%20sin%2030%5Eo%29%20N%3D461.88%20N)
Thus, the horizontal force being applied by the partner is 461.88 N.
Answer:
Explanation:
According to ohm's law
The current flowing through the wire is directly proportional to the potential difference applied across its ends , provided the temperature and other physical conditions of the wire like stresses and strains remains constant .
The magnitude of displacement =
the distance between start-point and end-point,
regardless of the route followed along the way.
Any motion that ends up where it started has zero displacement.
An object on a circular path starts over at zero displacement every time
it completes a full revolution. So does a race-car on a track.
