Answer:
C: It is the difference between the total kinetic and potential energy in a system.
Explanation:
The mass of sample = 10 g
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/ml
m = mass , g
v = volume , ml
Density is 5 g/ml and sample is 2 ml,so :
ρ = 5 g/ml
V = 2 ml
The mass :
Quantitative research, most likely, because charts and tables and graphs have to represent some kind of numerical data, like amounts of things and measurements of heights or changes over time, or whatever.
Answer: b
Explanation: alpha decay or particle consist of two protons and two neutrons hence it is a helium nucleus.
