Answer:
The formula for Impedance for circuit with R, C, and L are:

The impedance Z of the series RLC circuit depend upon angular frequency ω. Impedance is measured in ohms and resistance (R), inductance reactance and capacitive reactance. Series RLC circuit consist of the resistance, a capacitance and an inductance connected in the circuits. Electrical impedance is the measurement of the opposition that a circuit present in a current.
Answer:

Explanation:
We have given initial length of the steel guitar l = 1 m
Cross sectional area 
Young's modulus 
Force F = 1500 N
So stress 
We know that young's modulus 
So 

Now strain 


Answer:
accuracy refers to the deviation of a measurement from a standard or true value of the quantity being measured
The hotter molecules become, the faster they move around. The colder they are, the more slow and lethargic they are
Answer:570.54 N
Explanation:
Given
mass of man=76 kg

As man is standing over inclined building therefore
its weight has two components i.e. sin and cos component
Force perpendicular to inclined wall

F=570.54 N
