When the frequency of an ac circuit is decreased, the current in the circuit increases. which combination of elements is most li
zaharov [31]

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.

A crate of oranges with a total mass of 6.7 kg is being pulled across a skating rink (frictionless) with a rope that makes an an
Mama L [17]

Answer:

36.74 N

Explanation:

Given that:

A crate of oranges with a total mass  (m) = 6.7 kg

angle θ = 0.7 rad

angle θ = 0.7 * \frac{180}{\pi}

angle θ = 40°

acceleration = 4.2 m/s²

Given that:

T cosθ  = ma

T cos 40° = 6.7 × 4.2

T = \frac { 6.7 * 4.2}{cos \ 40}

T = \frac { 28.14}{0.7660}

T = 36.74 N

Thus, the tension in the rope = 36.74 N
