Answer a kind of radiation including visible light, radio waves,gamma rays,and x-rays,in which electric and magnetic fields vary simultaneously
Explanation:
90% of stars in the solar system are main sequence stars.
Explanation:
potential difference = current × risstance
see part a point3 current is same
v= IR
v = 8×0.2
v= 1.6
see part a point 5
this potential difference is less than cell
