Question

Knot : Watt : Fathom

• A. The terms are used by sailors
• B. The terms are used for installing electricity
• C. The terms are connected with rope
• D. They are units of measurement

Hint:

These are all units used to measure different quantities—knot (speed), watt (power), fathom (depth).

Answer 1

The Correct Option is D

The given problem requires us to identify the commonality among the terms 'Knot', 'Watt', and 'Fathom'. Let's explore each term and the options provided:

1. Knot: This is a unit of speed equivalent to one nautical mile per hour, commonly used in maritime contexts to describe the speed of vessels.
2. Watt: This is a unit of power in the International System of Units (SI), often used in contexts involving electricity and measuring power consumption or generation.
3. Fathom: This is a unit of length, especially used in maritime contexts to measure the depth of water.

Now, let's examine the options:

• The terms are used by sailors:
  While 'Knot' and 'Fathom' are indeed commonly used in maritime contexts, 'Watt' is not specifically related to sailing.
• The terms are used for installing electricity:
  This is incorrect because only 'Watt' relates to electricity, whereas 'Knot' and 'Fathom' do not.
• The terms are connected with rope:
  This option is incorrect as none of the terms are directly related to ropes.
• They are units of measurement:
  This is the correct option. All three terms represent different units of measurement: Knot for speed, Watt for power, and Fathom for length.

Thus, the correct answer is that the terms 'Knot', 'Watt', and 'Fathom' are all units of measurement.
