Answer:
Yes
Step-by-step explanation:
The answer to your question is 0.2
Answer:
79 electrons
Step-by-step explanation:
If it has 79 protons it will have a total proton charge of 79 so tho make the charge zero we need to add (79) electrons .Mathematically (1*79)+(-1*79)=0
3x - 4y = 7
-(3x + 2y = -5)
= 0 - 6y = 12
-6y = 12
y = -2
The resulting equation would be y = -2.
D=57 and r=30, then by the formula d=r*t
57=30*t.
dividing 30 on both sides we get, t= 57/30
t=1.9
