The International System Units or the SI units is scientific method of expressing the magnitudes or quantities of important natural phenomena. There are seven base units in the system, from which other units are derived. This system was formerly called the meter-kilogram-second (MKS) system.
Answer:
= 33.33 cm
Explanation:
Given:
When mass, =21 kg
distance travelled is = 140 cm
When mass, =5 kg
distance travelled is = ?
Hooke's law state that within elastic limit, when an external force is applied to a body, the body gets deformed and when the force is released the gets back to its original form.
Therefore according to the question,
= 33.33 cm
Distance travelled is 33.33 cm when mass is 5 kg.
Answer:isotopes
Explanation:Isotopes form when the number of neutrons and atomic number change except for the protons don't change
