What changes must be done to the wire to increase its conductance.​

Physics
1 answer:
777dan777 [17]3 years ago
8 0

Answer:

- Decreasing the resistance

- Using a shorter length

- Using a smaller area wire

Explanation:

Formula for conductance in wires is;

G = 1/R

Where;

G is conductance

R is resistance

This means that increasing the resistance leads to a larger denominator and thus a smaller conductance but to decrease the denominator means larger conductance.

Thus, to increase the conductance, we have to decrease the resistance.

Resistance here has a formula of;

R = ρL/A

Where;

ρ is resistivity

L is length of wire

A is area

Thus, to decrease the resistance, we will have to use a shorter length and smaller area of wire.

True or False. The mass of the pendulum determines the time of a period.
xxTIMURxx [149]

Answer:

False

Explanation:

The time period of a pendulum is given by :

T=2\pi \sqrt{\dfrac{l}{g}}

The terms used in the formula are :

l is length of pendulum

g is acceleration due to gravity

It is clear that the formula of time period of a pendulum is independent of its mass. So, the mass of the pendulum is not used to determine the time of a period. Hence, the given statement is false.

How many neutrons does an atom of Dubnium have in its nucleus
attashe74 [19]
Dubnium is a synthetic element ... Number 105.  It can be created
in a laboratory but it's not found in nature.

Fifteen (15) different isotopes of Dubnium have been created.  They all
have 105 protons in the nucleus of every atom, but they have anywhere
from 256 to 270 neutrons in each nucleus.

The most stable isotope of Dubnium is  ²⁶⁸Db , with 163 neutrons in the
nucleus.  That form of Dubnium atom has a 50-50 chance of surviving
for around 28 hours before it falls apart.

What causes convection currents, and what do they do?
frez [133]

Answer:

Convection currents are the result of different heating. Lighter material (warm) rises while heavier (cold) material sinks. This movement of the materials is what causes convection currents! (BTW, it happens in water, in the atmosphere, and in the mantle of Earth!

Explanation:

I hope this helps a little! :)

According to principle of conservation of energy, the total momentum of a system of masses in any direction remains constant unl
Sergeu [11.5K]
The principle of conservation of energy states that energy can neither be created nor destroyed, but can be changed from one form to another. The law of inertia on the other hand states that a body remains at a state of rest or motion on a straight line unless compelled by an external force. So i think that the answer is B, which is FALSE because the question is more related to the law of inertia(Newtons first law) than to the law of conservation of energy. Hope i helped.
