If the radius of earth be halved what will be the effect on time period?

The time period is given by the expression T = 2 pi R / v
R-the radius of the earth and v- the speed with which the equatorial part moves.
Let us assume the speed to be the same. So as radius R is reduced to half of its value ie R/2 then the time period too is reduced to half. ie T/2

What is acceleration due to gravity on surface of planet that has radius half that of earth and same average density as earth?
g=Gx4(pi)/3xr3x(rho)/r2=Gx4x(pi)x(rho)xr/3Now if the radius is halved then acceleration will also halve.
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?

Why gravity on earth is greater than that of moon?
Because the Earth has 80 times as much mass as the Moon has, and the greater radius of the Earth is not enough to cancel the effect of the mass difference.
What is Venus' radius as compared to the Earth's?
It is about 0.949 times Earth's radius.
What is the ratio of earth?
The answer depends on what characteristics being compared and the comparator. Possible examples:mass of earth to mass of sun (or a planet, or moon)radius of earth to radius of sun (or a planet, or moon)volume of earth to volume of sun (or a planet, or moon)mass of earth to its volumeperiod of rotation to period of revolutionorbital period to the average distance from the sunalbedo of earth to albedo of a planet, or moonThere are many other possibilities. Unfortunately, you have not specified any and so it is not possible to provide a more useful answer.
The alkaline earth element having the largest atomic radius is found in period?
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
Who invent radius of earth?
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
How does Venus compare with the earth radius and mass?
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's
What is Europa's diameter compared to earth?
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.
Mercury's radius is what percent of Jupiter's radius?
Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
Why is Hubble space telescope orbiting earth faster than Space Station?
It doesn't orbit earth faster. The ISS is in a lower orbit with a period of 91 minutes compared to the Hubble's orbital period of 96-97 minutes. Orbital periods generally increase with orbit radius and speed in the orbit decreases with increasing orbit radius.
If we double the distance from the Earth's center of a satellite that has been in synchronous orbit around the Earth what will its new period be?
It should have to travel twice as far((2Pi x radius) vs. 2(2Pi x Radius)). At the same speed it should take twice as long.
