Why Mercury is spherical in shape liquid?
The reason mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
What shape is the planet mercury?
Mercury is roughly spherical in shape, like most other planets. Its shape is determined by its gravity, which pulls the planet's material into a compact, rounded form.
What is the radius at the equator of mercury?
It's about 2440 kilometers. Mercury is almost spherical, so the radius is about the same everywhere.
Is Mercury perfectly round?
Mercury is definitely not perfectly round. All of our photos of Mercury show that it's covered in craters which cause ridges to form all over the planet. This means that it's not perfectly round.
Why are mercury drops spherical?
Mercury has a very high surface tension and does not easily wet most other surfaces. For a given amount of mercury, a sphere has the smallest possible ratio of surface area to volume and is therefor the lowest energy shape for the mercury.
Is mercurys shape a marble?
A marble has a spherical shape, and so has Mercury. But Mercury is a bit flattened at the poles, which a marble is not, so a marble is a more perfect sphere.
Would Mercury be large enough to be spherical if the radius was shrunk by 96 percent?
No, it would not, because the smallest possible radius for a spherical celestial body is 200 km (124 miles) and Mercury would only have a radius of 61 miles (98 km) if it was shrunk 96%.
What is the oblateness of Mercury?
Mercury has an oblateness, or flattening at the poles, of about 0.034 due to its rotation. This means it is more spherical than some other planets like Jupiter, which has a higher oblateness.
Is convex and concave mirrors also known as spherical mirrors?
Yes convex and concave mirrors are also known as spherical mirrors. If mercury coating is made on the convex side of the spherical then mirror is known as concave mirror. If mercury coating is made on the concave side the convex portion would reflect the light fallen so it is named as convex mirror. Actual just a small part of the sphere is taken out and this would act as the spherical mirror.
How many Mercury's does it take to fill the earth?
If you want to compare the volume:* Assume that both Earth and Mercury are spherical. That's a fairly good approximation. * Look up the diameter of Earth and Mercury. * Divide the diameter of Earth by the diameter of Mercury. * Raise this last result to the third power.
What are inner planet shapes?
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
