They vibrate back and forth
Answer:
The maximum length of the specimen before deformation is 240.64 mm
Explanation:
Strain = stress ÷ elastic modulus
stress = load ÷ area
load = 2130 N
diameter = 3.4 mm = 3.4×10^-3 m
area = πd^2/4 = 3.142 × (3.4×10^-3)^2/4 = 9.08038×10^-6 m^2
stress = 2130 N ÷ 9.08038×10^-6 m^2 = 2.35×10^8 N/m^2
elastic modulus = 126 GPa = 126×10^9 Pa
Strain = 2.35×10^8 ÷ 126×10^9 = 0.00187
Length = extension ÷ strain = 0.45 mm ÷ 0.00187 = 240.64 mm
It;s a physical change because the tablet dissolved and it made the water cooler
Answer:
Gradual refinement
Explanation:
Gradual refinement is the process whereby the System Development Life Cycle goes through a series of development stages, each stage/phase refining the previous one.
The most abundant is 35/17 Cl
explanation
This is because Chlorine 35/17 is the one close to the average atomic mass of chlorine which is 35.46 u making it to be the most abundant.
average atomic mass of chlorine is 35.46 + or- 0.02
