Moving the electron away from the nucleus requires energy, so the electrons in the outer shell will have more energy than ones in the inner shell. Electrons always have a charge of -1, so the charge in the inner and outer shell will be the same. Therefore the answer is 3
Answer:
2 m/s
Explanation:
Applying the formulae of velocity,
V = d/t............. Equation 1
Where V = Velocity of the body, d = distance, t = time
From the question,
Given: d = 600 m, t = 5 minutes = (5×60) = 300 seconds.
Substitute these values into equation 1
V = 600/300
V = 2 m/s.
Hence the velocity of the body when it travels is 2 m/s
Answer:
92.65256 cm^3
Explanation:
To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.
Given parameters:
Volume of the ruby = 575cm³
Density of the ruby = 3.97g/cm³
Unknown:
Mass of the largest ruby = ?
Solution:
Density is the mass per unit volume of a substance. It is an intrinsic property of matter that is unique to each of them.
Mathematically;
Density = 
Since mass is the unknown;
Mass = density x volume
Input the parameters and solve;
Mass = 3.97 x 575 = 2282.75g
The mass of the largest ruby is 2282.75g
