Explanation

A dipole in an electric field behaves in two ways:

• In a uniform electric field:

The two equal and opposite forces cancel each other out.

So, the net force on the dipole is zero.

But a torque is produced that tends to align the dipole moment parallel to the electric field.

• In a non-uniform electric field:

The dipole does experience a net force, and that force is generally not simply parallel to the field.

So the correct answer remains:

(D) None of these — because in a uniform electric field, the net force on a dipole is zero.

Option (C) would be correct only if we were talking about torque direction or net force in a non-uniform field.

Explanation

We know that:

x × x = x²

Reciprocal of x = 1/x

According to the problem:

(x × x) ÷ (1/x) = 18/26 × 27

Simplifying the equation:

x² ÷ (1/x) = 18/26 × 27

x³ = 18/26 × 27

Now, let's solve for x:

x³ = 486/26

x³ = 18.69 (approximately)

x = ∛(18.69) ≈ 2.67

The main sources of Islamic law are the

1. Holy Quran,
2. The Sunnah (the tradition or known practice of the Prophet Muhammad),
3. The Ijma (consensus) 
4. The Qiyas (analogy).
   

Explanation

The wavelength of the audible frequency (20 Hz to 20 kHz) audible to the human ear is approximately 17 m to 17 mm.

Bats use slightly higher frequencies, so they can solve targets smaller than 17mm.

The wavelength of audible sound is much longer than the wavelength of visible light.

Explanation

Simple mathematics question … (solve for X)

12/22 = 30/X

12X = 22 * 30

12X = 660

X = 55

Explanation

We are given:
A wire with resistance R = 6 Ω
It is cut into two equal parts
These two parts are then connected in parallel

Step 1:

Resistance of each half
When a wire is cut into two equal parts, the resistance of each half becomes half:
Rhalf​=6/2​=3Ω

Step 2:

Two 3 Ω resistors in parallel
Use the formula for two resistors in parallel:
Req​1​=1/3​+1/3​=2/3​

Req​=3/2​=1.5Ω

Explanation

The "slinky approximation" refers to a model

Where a spring (like a slinky) is considered to be composed of a series of small masses connected by massless springs

And its stretched length is significantly larger than its original unstretched length.

This approximation is useful for studying the dynamics of slinkies, particularly when the stretches are large. 

Explanation

"He is the tallest boy in the school."
Correct use of the superlative form "tallest" when comparing one person with all others in the group (the school).

Explanation

The drum of a Photostat machine (also known as a xerox machine) is made of a material called selenium,

That is a photoconductive element.

This means that when exposed to light

It becomes conductive, allowing the machine to transfer the image onto the paper.
