A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combin
Greeley [361]

Answer:

<em>The equivalent resistance of the combination is R/100</em>

Explanation:

<u>Electric Resistance</u>

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}

If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:

\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}

This sum is repeated 10 times. Operating each term:

\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}

All the terms have the same denominator, thus:

\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}

Taking the reciprocals:

R_e=R/100

The equivalent resistance of the combination is R/100

Alex_Xolod [135]
<span>The four main stages of the sun's predicted evolution in order from beginning to end are as follows: main sequence (when a star's core is fusing hydrogen); red giant (larger star, where no hydrogen remains in the core); planetary nebula (surrounds an aging star; ring shaped nebula made of gas); and white dwarf (smaller star that tends to be as large as an actual planet; after nebula state).</span>

The time spent on design will vary, dependent on the complexity of the problem. Why is it important to give the design process a
lord [1]

Answer:To ensure significant dialogue which will guarantee that the needed Products meets specifications

It will help to develop a better Operational model for the users.

Explanation: The design phase is one of the most critical phase in product development,it is in this phase that the product structure, contents and specifications are put into action. It is necessary that the end users have a significant time to dialogue with the project or product development team to guarantee that the end product meets specifications.

It is also necessary to spent adequate time in order to make the product user friendly (easy to operate and maintain).

How does newtons law intertia relate to a index card being placed on a cup then a penny ontop of the index then flicking it off?
Paha777 [63]

The law says any object resist any change in their state of motion unless subjected to an external force. In this case the penny stay in it's position of rest and falls in the cup. While the card, that is subjected to external force, change its state.
