Answer:

To describe motion accurately and completely, a frame of reference is necessary. frame of reference ( or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix ( locate and orient ) the coordinate system and standardize measurements within that frame.

Explanation:

The different observations occur because the two observers are in different frames of reference. A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.

4. Write a general equation for voltage (V), field strength (V/m) and distance (m) showing the relationship between these three

liq [111]

The general equation for voltage, field strength and distance is $E=\frac{V}{d}$

<u>Explanation:</u>

Electric field is the measure of potential crossing per unit distance. In other terms we can say it as the work done to displace the charge from infinity to a point and the potential difference between them. The unit of Electric field is written as V/m, it is also known as field strength.

So the field strength is directly proportional to the potential and inversely proportional to the displacement or the distance covered by the charge. Thus, $E = \frac{V}{d}$ is the general equation relating voltage, field strength and distance.

2. What is the structure of electric circuits? Can a branch of a circuit contain three elements? Can there be a branch which doe

ddd [48]

First electric circuit means, the circuit has elements like resistors, capacitors, and inductors along with sources. Any electric circuit comprises nodes, branches, and meshes.

The joining point of two elements is called a node. The element between two nodes is called a branch. In branch, only one series element is possible to connect but in parallel, it can have N number of elements. No branch without elements in electric circuits.

A resistor is an electrical aspect that limits or regulates the go with the flow of electrical modern-day in a digital circuit. Resistors can also be used to offer a selected voltage for an energetic device together with a transistor.

The resistor is described as. A passive electrical issue with two terminals that can be used for both limiting or regulating the glide of electric contemporary in electric circuits. the main cause of the resistor is to lessen the modern-day go with the flow and to lower the voltage in any unique part of the circuit.

A resistor works by using proscribing the float of current, it may try this in one in all 3 approaches: first off, by using a much less conductive cloth, secondly by making the conductive fabric thinner, and sooner or later by making the conductive fabric longer.

A fox ﬂeeing from a hunter encounters a 0.700 m tall fence and attempts to jump it. The fox jumps with an initial velocity of 7.

iris [78.8K]

Answer:0.61 m

Explanation:

Given

Initial velocity (u)=7.40 m/s

launch angle $\theta =45^{\circ}$

height of fence=0.7 m

Trajectory of Projectile is given by

$y=x\tan \theta -\frac{gx^2}{2u^2\cos^2\theta }$

For x=2.1 m

$y=2.1\tan (45)-\frac{9.8\times 2.1^2}{2\times 7.4^2\times (\cos 45)^2}$

$y=2.1-0.789$

$y=1.31 m$

At x=2.1 m Y=1.31

therefore Fox clear fence by a margin =1.31-0.7=0.61 m

An example of a land feature formed by river erosion is?

KatRina [158]

<span>There are various examples of land features formed by river erosion. One of them is Delta. A delta is formed when sediments are deposited in a place where a river flow into an ocean or lake and build up a land form. Thus, a river delta is a land form that occurs as a result of deposition of sediments carried by a river as the flow leaves its mouth and enter a slow moving or stagnant water.</span>
