Answer:
I think its 12 cm itself. Because in the question it is said that the length is same in all temperature
A graduated cylinder measures the volume of a liquid.
A stopwatch measures the amount of time that elapses.
A scale measures the mass of objects.
A thermometer measures the temperature of any object.
Because we are measuring rain, a liquid, we would want to use a tool that would allow us to collect the rain for measuring. Therefore, the tool e would use to measure the amount of rainfall would be A. a graduated cylinder.
When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

K=1/2 mv2
M=?
41.6kj convert to joules by multiplying by 1000 so it will be 41,600J because the unit of kinetic energy is in joules.
41,600=1/2(m)(8)
Arrange the equation it will be:
M= 41,600/4 = 10,400
Final answer is:
m= 10,400 kg
