Well , its a easy problem  

By ohms law,  

we have V= IR  

Where V is the voltage applied across the wire and R is the resistance and I is the current  

=> R = V/I  

=> R = 12/0.3 = 40 ohm

Leya [2.2K]
Alpha particles are released by proton rich unstable nuclei. It has no electrons to balance the protons making it positively charged particles moving at very high speeds. Gamma articles are electromagnetic waves of short wavelength and high frequency. It has a speed same as the speed of light. Beta particles are released by neutron rich unstable nuclei. It has a speed of less than the gamma particles.

Pani-rosa [81]

A. To show how precise your measurements were

Explanation:

It is important to use the correct number of significant digits when reporting the results of an experiment because they show how precise measurement are.

  • Precision is the ability to reproduce a particular set of results in an experiment.
  • Every instrument have their precision level.
  • The precision levels shows to what extent the values obtained can be trusted..
  • Significant figures are not only important in recording measurements, they are also needed for calculations in science.
