Super Invar, an alloy of iron and nickel, is a strong material with a very Low coefficient of thermal expansion (0.20x10^-6/°C).

A 1.6-m-long tabletop made of this alloy is used for sensitive laser measurements where extremely high tolerance are required. How much will this alloy table expand along expand along its length if the temperature increase 5°C?

Answer:

The alloy table will expand by 1.6*10^-6 m along its length if the temperature increase 5°C.

Explanation:

let k be the coefficient of thermal expansion

let T be the change in temperature of the alloy table

L1 be the initial length of the table

L be the expanded length of the table

k = L/(L1*T)

L = k*L*T

  = (0.20*10^-6)(1.6m)(5)

  = 1.6*10^-6 m

therefore,The alloy table will expand by 1.6*10^-6 m along its length if the temperature increase 5°C.

andre [41]

Answer:  10 m/s

We're told the speed is constant, so it's not changing throughout the time period given to us. So throughout the entire interval, the speed is 10 m/s.

An electric dipole consists of a particle with a charge of 6 x 10–6 c at the origin and a particle with a charge of –6 x 10–6 c
mote1985 [20]

An electric dipole consists of a particle with a charge of 6 x 10⁻⁶ c at the origin and a particle with a charge of –6 x 10⁻⁶ c on the x axis at x = 3 x 10⁻³ m. Its dipole moment is 18 x 10⁻⁹ Cm

Dipole moment of a dipole is dependent on the charge of the dipole and the distance between the two charges.

Electric Dipole consists of two charges which are equal and opposite in charge i.e. positive and negative charges.

Given,

Dipole moment, p = ?

Charge, q = 6 x 10⁻⁶C

Distance between charges, d = 3 x 10⁻³ m

Dipole moment (p) is given by:

p = charge x distance between the two charges

p = 6 x 10⁻⁶ x 3 x 10⁻³ Cm

p = 18 x 10⁻⁹ Cm

The dipole moment for the given charge configuration is 18 x 10⁻⁹ Cm

At 20°c, the resistance of a sample of nickel is 525 ohms. what is the resistance when the sample is heated to 70°C?​
Ipatiy [6.2K]

The resistance of the sample is 682.5\Omega

Explanation:

The relationship between resistance of a material and temperature is given by the equation

R(T)=R_0(1+\alpha (T-T_0))

where

R_0 is the resistance at the temperature T_0

\alpha is the temperature coefficient of resistance

For the sample of nickel in this problem, we have:

R_0 = 525 \Omega when the temperature is T_0 = 20^{\circ}C

While the temperature coefficient of resistance of nickel is

\alpha = 0.006/^{\circ}C

Therefore, the resistance of the sample when its temperature is

T=70^{\circ}C

is

R=(525)(1+0.006(70-20))=682.5 \Omega
