scientists can prove the answer of the chemical reaction and in every case
The statement about "<span>efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.</span>
Because you know that gravity is in m/s^2 so, period will be measured in seconds. You know the cable is 12m long and gravity is 9.81 solve for T (period) 2π12sqrt(9.81)=6.94922
Explanation:
Iron transition metal
Potassium Alkaline metal
Strontium Alkaline earth metal
Platinum transition metal
The periodic table arranges elements based on their atomic numbers into periods and groups. Atomic number is the number of protons an atom contains.
On the periodic table:
Group IA is called Alkaline metal
Group IIA is the Alkaline earth metals
Group IIIA Boron family elements
Group VIIA Halogens
Group O Noble gases or inert gases.
Group IIIB to IIB Transition elements.
Running a check of the given elements on the periodic table will confirm answer.
