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.

a voltmeter and an ammeter are used to respectively monitor the voltage across the current through the resistor
dusya [7]

When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.

  1. When current flows through loop , it gets conducted.
  2. Due to this Electric field is generated . This happens due to induced magnetic field.
  3. The free electrons were at rest until current is there , still ammeter detects some deflection.
  4. This deflection is due to zero current.
  5. Due to magnetic field , current in coil changes.
  6. Mathematically, \alpha =-\frac{d\beta }{dt}
  7. The presence of conducting loop is not necessary for having electric field.

e= -\frac{d\beta }{dt}

e=-L\frac{d\beta }{dt}

i= i0 \left \{ {{y=0.63} \atop {x=t}} \right.

i=0.63 io

The first hill of a roller coaster is 42 meters high. The top of the second hill of the one
Marta_Voda [28]

Answer:

Part a)

Speed of the roller coaster is

v = 13.3 m/s

Part b)

Since it is moving with non zero speed at some height above the ground

So we will have

Kinetic energy + Potential energy Both

Explanation:

As we know that there is no friction on the path

So here we can use mechanical energy conservation law

so we will have

Part a)

U_i  + K_i = U_f + K_f

mgh + 0 = \frac{1}{2}mv^2 + mgH

34500(9.81)(42) = \frac{1}{2}(34500)v^2 + 34500(9.81)(33)

v = 13.3 m/s

Part b)

Since it is moving with non zero speed at some height above the ground

So we will have

Kinetic energy + Potential energy Both

Each ball has a negligible size and a mass of 11.5 kg and is attached to the end of a rod whose mass may be neglected. The rod i
Digiron [165]

Answer:

3.31m/s

Explanation:

Angular momentum for 3s is

L = L_i_n_i + L_3_s

L = 2(11.5kg) + \int\limits^ {3s}_ {0s} {(t^2 + 2)} \, dt

L = 23kg+(\frac{t^3}{3} +2t)^ {3s}_ {0s}\\\\L=38kgm/s

Moment if inertia is

I = 2ml^2

I = 2(11.5)(0.5)^2\\\\I=5.75kgm^2

Angular speed

ω = L/I

= 38 / 5.75\\\\=6.61

The speed of each ball is

V = ωL

= 6.61\times0.5\\\\= 3.31m/s
