Answer:
The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor
Explanation:
The impedance of an LCR circuit shown as
Z = √R² + (X↓l - X↓c)²
Z = √R² + (2π∨L - 1/2π∨c)²
Variation of Z with respect to υ is shown in the figure.
As υ increases, Z decreases and so the current increases.
At υ = υ↓r
Z is minimum, current is maximum. Beyond
υ = υ↓r
Z increases and so current decreases.
so the combination of circuit elements that is most suitable to comprise
the circuit is R, L and C.

Answer:
The correct answer is option 'b': The rate of change of f changes from decreasing to increasing.
Explanation:
In differential calculus the behavior of any smooth function can be understood on the basis of slope of function alone. As slope of the function is the representation of rate of change of function.
Mathematically
Given as any function we have
1) if then the function is increasing
2) 1) if then the function is decreasing
3) 1) if then the function reaches a critical point.
Thus the nature of the function at any point is specified by the nature of the differential at the point provided the function is defined at that point at which we need to check the behavior.
Answer:
Acceleration =0
Explanation:
There are two forces on the box in horizontal direction.
First one is horizontal component of 30N at 45°.
Another one is given in opposite to direction of motion mean opposite to this force.
Which is = 2.22 N
Now we know F (net) =mass*acceleration(center of mass)
21.2-21.2 =10*acceleration
acceleration =0
He will swim 180m if he stays at a constant rate of 30m/min
Explanation:
First I’m going to use 6 min for the 5min 60s
Then if he swims 30m/min then I’m 6min, 30•6 he’ll swim 180m
Hope this helps!
