Answer:
So the force of attraction between the two objects is 3.3365*10^-6
Explanation:
m1=10kg
m2=50kg
d=10cm=0.1m
G=6.673*10^-11Nm^2kg^2
We have to find the force of attraction between them
F=Gm1m2/d^2
F=6.673*10^-11*10*50/0.1^2
F=3.3365*10^-8/0.01
F=3.3365*10^-6
Elliptical and Spiral have some similarities, they both are huge and contain lost of dust and also they are held by gravitational forces.

Answer:
Explanation:
Giant impact has resulted into formation of celestial bodies such as moon.
Moon was formed years after the Earth was formed. When Earth collided with very big size bodies, there was vaporization of chunks of the planets in to the space. Gravity plays its role and bounded those particles together thus forming moon.
This formation explains Moon is made up of lighter elements and contains too little iron where as Mercury was formed with the rest of the planets and just like earth, its core is formed first which is of iron and then collected the lighter elements to form crust and mantle.
Though both Moon and Mercury were the result of giant impacts yet they have different elements because mercury was made earlier and its is closer to moon hence it collected heavy elements such as iron to for the formation where as moon is the result of collision of Earth and other Mars- sized body hence its constituent particles are different that of mercury.
<span>We can find the period P of one cycle, and then we can use the period to find the gravitational acceleration g on this planet.
P = (132 s) / (107 cycles) = 1.2336 s/cycle
The period P is 1.2336 seconds. This means that it takes 1.2336 seconds for the pendulum to swing back and forth one.
Now we can use the period P to find the gravitational acceleration g.
The equation for the period of a pendulum is as follows:
P = 2 pi \sqrt{L/g}
P^2 = (4 pi^2) L / g
g = (4 pi^2) L / P^2
g = (4)(pi^2)(0.540 m) / (1.2336 s)^2
g = 14.0 m/s^2
The acceleration of gravity on the planet is 14.0 m/s^2.</span>
