Answer:
Therefore the number of proton in the given system is 450.
Explanation:
Given that, a system has 1223 particles.
Let x number of proton be present in the system.
Then the number of electron is =(1223-x)
The charge of a proton is = 1.602×10⁻¹⁹ C
The charge of an electron = - 1.602×10⁻¹⁹ C
The charge of x protons is =( 1.6×10⁻¹⁹×x) C
The charge of (1223-x) electrons is = - 1.6×10⁻¹⁹ (1223-x) C
According to the problem,
(1.6×10⁻¹⁹×x) +{ - 1.6×10⁻¹⁹ (1223-x)}= -5.328×10⁻¹⁷
⇒1.6×10⁻¹⁹(x-1223+x)=-5.328×10⁻¹⁷
⇒2x-1223= -333
⇒2x= -333+1223
⇒2x=900
⇒x=450
Therefore the number of proton is 450.
Answer:
1.94 kg
Explanation:
we have given density of water = 1 gm/
the initial reading of the scale = 19 N
change in reading of scale =10 N
we have to find the mass of the block when the block is lowered in water
mass of the block when it is lowered in the water is given by
here g is the gravity of acceleration which value is given by 9.8
so the mass of the block =
Hey There!!
Your answer will be A. It get longer.
Because, The kinetic energy of its atoms increase. They vibrate faster. This means that each atom will take up more space due to its movement so the material will expand. Some metals expand more than others due to differences in the forces between the atoms / molecules. . . .
Hope This Helps <3!!
