Answer:
4 times the mass of Earth
Explanation:
= Mass of Earth
= Mass of the other planet
r = Radius of Earth
2r = Radius of the other planet
m = Mass of object
The force of gravity on an object on Earth is
The force of gravity on an object on the other planet is
As the forces are equal
So, the other planet would have 4 times the mass of Earth
A light meter, because illu is a root for light
Two influential product that Tesla (Elon Musk) made is his Model X, and his power wall. The Model X revolutionised cars and driving in general, with self driving, and many components to help. The powerwall made electricity another level. Along with his solar-shingle roof, it made homes efficient, and 'green'.
Hope this helped!! :)
Since gas is sealed in container, volume of gas will ramain constant. from ideal gas equation PV=nRT, P/T = nR/V ==> P/T = constant.( constant since v is constant so whole term must be constant). therefore, (P/T)1 = (P/T)2.==> 50/300 = P2/360. ==> P2= 50X360/300 = 60KPa. Hope this helps
Sound travels fastest through a solid, because the molecules are most tightly packed together in a solid, helping the sound waves jump from one molecule to another faster. Sound travels second fastest through a liquid because the molecules are packed together second most, and sound travels slowest through gasses.
Sound travels fastest in solids, slower in liquids, and slowest in gasses.
