3 bulbs are in series and the same 3 bulbs are in parallel with the same battery. Which bulbs will be dimmer?
Marina86 [1]

3 bulbs are in series and if the same 3 bulbs are in parallel with the same battery then the bulbs that are connected in parallel  will be dimmer

<h3>What is power?</h3>

The rate of doing work is known as power. The Si unit of power is the watt.

Power =work/time

The mathematical expression for the electric power is as follows

P = VI  

The same current flows through both bulbs when they are connected in series. A greater voltage drop across the bulb with the higher resistance will result in higher power dissipation and brightness. In the case of the parallel combination, the bulb will be dimmer

Thus, If the same three bulbs are connected in series and parallel with the same battery, the parallelly connected bulbs will be dimmer, therefore the correct option is A

Suppose you were asked to demonstrate electromagnetic induction. Which of the following situations will result in an electric cu
steposvetlana [31]
D. All of the above. When a wire loop is moved or rotated in a magnetic field, there is a change in magnetic flux which produces emf in wire loop and hence electric current is produced.

The turntable in a microwave oven has a moment of inertia of 0.039 kg⋅m2 and is rotating once every 4.4 s . Part A What is its k
gayaneshka [121]

To solve this problem it is necessary to apply the concepts related to Kinetic Energy, specifically, since it is a body with angular movement, the kinetic rotational energy. Recall that kinetic energy is defined as the work necessary to accelerate a body of a given mass from rest to the indicated speed.

Mathematically it can be expressed as,

KE = \frac{1}{2} I\omega^2

Where

I = Moment of Inertia

\omega =Angular velocity

Our values are given as

I = 0.039kg\cdot m^2

A revolution is made every 4.4 seconds.

\theta = 1 rev \rightarrow 4.4s

\Rightarrow \omega = \frac{1rev}{4.4s}

If the angular velocity is equivalent to the displacement over the time it takes to perform it then

\omega = 0.2272rev/s(\frac{2\pi rad}{1rev})

\omega = 1.42rad/s

Replacing at our previous equation we have,

KE = \frac{1}{2} I\omega^2

KE = \frac{1}{2} (0.039)(1.42)^2

KE = 0.03993J

Therefore the kinetic energy is equal to 3.9*10^{-2}J
