Answer:
Slit separation,
Explanation:
It is given that,
Wavelength of light,
The angle between the central bright fringe and the second dark fringe,
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is . Hence, this is the required solution.
The answer to the question presented above would be PAR-Q or the <span>Physical Activity Readiness Questionnaire. The purpose of this questionnaire is to identify if you have any medical risks and to know your overall medical background for future reference of prevention of complications whenever you're training.</span>
Answer:
the surface this works out to 9.8 m/s squared.
Answer: 2.83 J/mol
Explanation:
Heat of solution, sometimes interchangeably called enthalpy of solution, is said to be the energy released or absorbed when the solute dissolves in the solvent. A solute is that which can dissolve in a solvent, to form a solution
Given
No of moles of CaCl = 7.5 mol
Total energy used = 21.2 J
Heat of solution = q/n where
q = total energy
n = number of moles
Heat of solution = 21.2 / 7.5
Heat of solution = 2.83 J/mol
