She likes hiking, swimming, and biking.

It sentence maintains parallel structure (all gerunds: hiking, swimming, biking).

Explanation

When two resistances are connected in parallel, the net resistance (Rnet) is calculated using the formula:

1/Rnet = 1/R1 + 1/R2

where R1 and R2 are the individual resistances.

In this case, R1 = 6 Ω and R2 = 12 Ω, so:

1/Rnet = 1/6 + 1/12 = 1/4

Rnet = 4 Ω

Therefore, the net resistance of the two resistances connected in parallel is 4 Ω.

Explanation

When capacitors are connected in parallel, the total capacitance (Ct) increases, as the effective plate area and charge storage capacity increase.

The formula for total capacitance in parallel is: Ct = C1 + C2 + ... + Cn

In series connection, the total capacitance decreases, as the effective plate area and charge storage capacity decrease.

The formula for total capacitance in series is: 1/Ct = 1/C1 + 1/C2 + ... + 1/Cn

Explanation

• A pair of unlike parallel forces (forces that act in opposite directions) with different lines of force produce a couple.
• It is also known as a moment or torque.
• This is a rotational force that tends to cause rotation around a pivot point or axis.

Explanation

• In a parallel circuit, if one bulb blows, the other bulb will remain the same.
• This is because each bulb in a parallel circuit has its own independent path to the power source.
• The failure of one bulb does not affect the current flowing through the other bulb's path.

Explanation

Explanation

• In a parallel circuit, each branch has its own path for current to flow.
• If one branch is interrupted, the other branches will continue to operate normally.

Explanation

In most businesses and homes, electrical circuits are connected in parallel to ensure that:

• Each device receives the same voltage
• If one device fails or is turned off, others remain operational
• The entire circuit doesn't fail if one device is disconnected
