Let, time taken is t.
So,
( Here, us is vertical component of initial velocity )
Now, distance covered from the base of the cliff is :
Therefore, time taken and distance covered is 3.873 s and 19.365 m.
Hence, this is the required solution.
Answer:
- find the difference
- "vector addition" is likely to be larger than displacement
Explanation:
No doubt your curriculum materials have an adequate discussion of error and how it is determined.
a) The error between two values is the difference between an approximation and the true value. You determine it by subtracting the true value from the approximation.
In the case of a trip, you need to decide what is the "true value" and what is the "approximation." The wording here suggests that the "displacement of the actual trip taken" is to be considered the "true value." Then, you determine the error by subtracting that displacement from the "vector addition."

b) In Euclidean geometry, a vector is a straight-line path. In the real world, we use the term <em>vector</em> to refer to the direction taken by an object, generally along a curved path at some relative distance from the Earth's surface. The direction reference may change along the path, so that following a given "vector" will usually result in a curved path (not a great circle) on the Earth's surface.
__
c) The curved path from a point A to a point B on the Earth's surface will always be longer than the straight-line path between the same two points. In the case of points on opposite sides of the world, the straight-line path is through the center of the Earth, whereas the "vector addition" will be some path along the surface of the Earth.
You need to decide the meaning of "actual trip taken," as any actual trip will generally involve all the changes in direction and ups and downs along the way. If you consider "the actual trip taken" to be the difference between starting and ending coordinates, then the "vector addition" will always be longer.
S~ cientists publish their original research in scientific journals, which are fundamentally different from news magazines. The articles in scientific journals are not written by journalists – they are written by scientists. Scientific articles are not sensational stories intended to entertain the reader with an amazing discovery, nor are they news stories intended to summarize recent scientific events, nor even records of every successful and unsuccessful research venture. Instead, scientists write articles to describe their findings to the community in a transparent manner.
The charge on the positive plate is 1.734* C
Given,
V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*
We know C=∈ * = 8.85* *=19.275* F
Also, Q = C V = 19.275* * 9 = 1.734* C
<h3>Charge </h3>
When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
