Explanation

Fringe spacing in a double-slit experiment is inversely proportional to slit spacing (Δy ∝ 1/d).

So, doubling the slit spacing results in the fringe spacing being halved.

Explanation

The average daily food intake provides about 8,000–10,000 kJ, similar to the energy in 0.33 liters of petrol.

This comparison helps relate human energy needs to fuel energy.

Explanation

A capsid is a protein coat surrounding a virus's genetic material, and it's composed of individual protein subunits called capsomeres

Explanation

The SI unit of stress is the Pascal (Pa), which is equivalent to Newtons per square meter (N/m²).

Therefore, the SI unit of stress is the same as that of pressure. 

Explanation

Archaebacteria, especially thermophiles, can survive extreme conditions, tolerating temperatures up to 120°C.

They are often found in hot springs, hydrothermal vents, and other extreme environments.

Explanation

Class boundaries define the exact limits for grouped data.

For a class centered at 25 inches, a typical class width (e.g. 5.2) gives boundaries like 23.50 to 28.70.

Explanation

A standard die has 6 numbers: 1, 2, 3, 4, 5, 6

Odd numbers: 1, 3, 5 → 3 outcomes

Total outcomes: 6

Probability = 3/6 = 1/2

Explanation

 The unimportant factor in describing a satellite's orbit is the mass of the satellite. 

Explanation

Cellular respiration is the process by which cells break down glucose to produce ATP (energy).

It occurs in mitochondria.

It provides energy for all cellular activities.

Explanation

Arthrobotrys is a soil-dwelling carnivorous fungus that traps and digests nematodes using specialized hyphal structures.

It plays a role in biological control of harmful soil pests.
