Weight has to do with how hard gravity is pulling on it. While mass is do to with the atoms in the matter.
No
1. I know it
2. If you watch the odd1sout, he did a science project about this and it had LITERALLY NO EFFECT
Answer:
12.4×10^3 V
Explanation:
From E=hc/wavelength= eV
The voltage becomes
V= hc/e* wavelength
V= 6.63*10^-34*3*10^8/1.6*10^-19*1*10^-10
Note that the energy of the photon is transferred to the electron. That is the basic assumption we have applied in solving this problem. The kinetic energy of the electron is equal to the product of the electron charge and the acceleration potential.
They are both physical changes (change in physical structure/appearance)
hope this helps :)
