Explanation

Direction: It is not enough for a detective to see things he must be able to reason quickly and accurately. That is to say, he must see with his mental eye as well as with his physical eye. All detectives talk about deducing things. Sherlock Holmes used to deduce a man's character by an examination of his watch, his walking stick, or his hat. His idea was that every criminal leaves a number of traces of his crimes. It is a detective business to notice them and to interpret them.

Explanation

Charge is quantized and exists in discrete amounts.

The smallest possible charge is that of a single electron or proton, which is 1.6 × 10−¹⁹C.

Explanation

Step 1: Recall the formula for torque

Torque (τ) is related to the change in angular momentum (L) over time (t) by the formula: τ = ΔL / Δt

Step 2: Calculate the change in angular momentum

ΔL = 5L - 2L = 3L

Step 3: Calculate the torque

τ = ΔL / Δt = 3L / 3 = L

Chaotic means افراتفری

Disorderly means بے چین

Explanation

In an arithmetic progression, the sum of n terms between a and b is given by: Sum = n(a+b)/2

This formula uses the first and last terms to find the total of evenly spaced values.

Explanation

To find the sum, we need to calculate each term:

i^101 = i (since i^1 = i and the powers repeat every 4 terms)

i^102 = i^2 = -1

i^103 = i^3 = -i

i^104 = i^4 = 1

Now, let's add them up:

i + (-1) + (-i) + 1 = 0

Explanation

The square root of any prime number is not a perfect square.

Therefore, √𝑝 is irrational, meaning it cannot be expressed as a fraction of two integers.

Explanation

The phrase “went on” followed by a gerund (-ing form) means to continue doing something.

So, the correct structure is: He went on explaining the benefits.
