Explanation

Atto (a) = 10⁻¹⁸

Femto (f) = 10⁻¹⁵

Nano (n) = 10⁻⁹

Peta (P) = 10¹⁵

So, Atto has the smallest (lowest) value.

Explanation

Power = Work / Time = (Force × Distance) / Time

= (Mass × Acceleration × Distance) / Time

= [M] × [LT-2] × [L] / [T] = [ML2T-3].

Explanation

Explanation

j¹⁰⁵ = j^(4*26 + 1) 

= (j⁴)^26 * j¹ 

= 1²⁶ * j 

= j.

Explanation

CSMA/CD is used in BUS topology to manage how devices share the communication line and avoid data collisions.

It listens before sending data and stops transmission if a collision is detected — ensuring efficient use of the medium.

Explanation

h = u²/2g = (16)² / (2 × 9.8) = 256 / 19.6 = 13.06 ≈ 13.1 m.

Explanation

We use "sorry for" to express sympathy toward someone.

Example: She was sorry for the injured dog.

Explanation

If θ = sin⁻¹x, then sin(θ) = x.

From the identity:

cos²θ + sin²θ = 1,

⇒ cos(θ) = √(1 − x²).

Explanation

sin45° = 1/√2 and cos45° = 1/√2.

So, sin45° + cos45° = 1/√2 + 1/√2 = 2/√2 = √2.

Explanation

Step 1: Determine the value of each power of j

j¹⁰ = (j²)⁵ = (-1)⁵ = -1.

j¹⁰⁰ = (j²)⁵⁰ = (-1)⁵⁰ = 1.

j¹⁰⁰⁰ = (j²)⁵⁰⁰ = (-1)⁵⁰⁰ = 1.

Step 2: Calculate the expression

1 + j¹⁰ + j¹⁰⁰ - j¹⁰⁰⁰ = 1 + (-1) + 1 - 1 = 0.
