The roadway would cause diffuse reflection due to its rough surface

some examples where diffused reflection

• Desert sand,
• disturbed water surface,
• and rough roads  
  

Explanation

To find the resultant of two forces acting at right angles, use the Pythagorean theorem:

Resultant = √(3² + 4²) = √(9 + 16) = √25 = 5N

Explanation

A carburetor uses the principle of Bernoulli's equation, which states that as the speed of a fluid increases, its pressure decreases.

In a carburetor, air flows through a constricted section called a venturi.

This increased airflow creates a lower pressure area, which then draws fuel from the fuel reservoir into the air stream, effectively mixing them. 

Explanation

Kinetic energy (KE) is expressed as: 

KE = 1/2 * mv² 

Where: m = mass (dimensions: M¹), v = velocity (dimensions: L¹T⁻¹), and v² = (L¹T⁻¹)² = L²T⁻². 

Therefore, the dimensions of KE are: 

KE = M¹ * (L²T⁻²) = M¹L²T⁻² 

Explanation

Using the formula: λ = c / f (where λ = wavelength, c = speed of light, and f = frequency)

λ = (3 × 10^8 m/s) / (90 × 10^6 Hz) ≈ 3.33 m.

Explanation

Convex lenses converge light rays and are used in reading glasses to magnify close-up text.

A short focal length provides greater magnification, making it ideal for reading.

Explanation

Astrology deals with how the positions and movements of celestial bodies influence human behavior and fate.

It is different from astronomy, which is the scientific study of celestial objects.
