A very long straight current-carrying wire produces a magnetic field of 20 mt at a distance d from the wire. to measure a field
1 answer:
The distance covered is 4d.
<h3>What is the distance?</h3>- Distance is a measure of how far apart two objects or locations are using numbers.
- The distance can refer to a physical length or an estimate based on other factors in both daily language and physics (e.g. "two counties over").
- The terms "distance from A to B" and "distance from B to A" are frequently used interchangeably.
- A distance function or metric is a technique to describe what it means for components of space to be "near to" or "far away" from each other in mathematics.
- It is a generalization of the idea of physical distance. Distance is a non-numerical unit of measurement in psychology and the social sciences; psychological distance is the separation of an object from itself along dimensions including time, space, and isolation.
We know that
the magnetic field is inversely proportional to distance.

Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
Answer:
The original dimensions of the building is 95 ft × 38 ft.
Explanation:
Let the original length be 'l' and original width be 'w'.
Given:
Original length (l) =
Original width = 'w'.
So,
Now, as per question:
Length and width is increased by 7 ft.
So, new length (l') =
New width (w') =
New perimeter (P) = 266 ft
Perimeter is given as:
Therefore, original width = 38 ft.
Original length is,
Hence, the original dimensions of the building is 95 ft × 38 ft.
