To find the average speed, we must calculate the total distance covered by the object and then divide it by the total time of the motion.
The total distance covered by the object is
while the total time of the motion is
Therefore, the average speed of the object is
Answer:
a.
b.
Explanation:
The inertia can be find using
a.
now to find the torsion constant can use knowing the period of the balance
b.
T=0.5 s
Solve to K'
The correct answer is B.g/mL
After conversion from cm³ to ml we get 3mili litres.
<h3>What are fundamental units?</h3>
The SI comprises a coherent system of units of measurement starting with seven base units ,which are the second,metre, kilograms,ampere, kelvin, mole and candela. SI unit is a scientific method of expressing the magnitude or quantities of important natural phenomenon.
When measured an object by the help of ruler I get the value 3cm and when I calculated its volume is 3cm³ . After converting it from cm³ to ml we get 3ml .
