Does the inertia of an object change as the object’s velocity changes explain

1 answer:

8 0

Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity. Good luck on your assignment and have a great day! :D

Rank the band gap energies of the following solids. Metal insulator semiconductor superconductor I. large band gap energy II. sm

Anon25 [30]

Answer:

Metal - smallest band gap energy

insulators - large band gap energies

semiconductor - Band gap of intermediate energies

superconductor cooper pair theory is applied for calculating gap energies.

Explanation:

Metal - smallest band gap energy

it is due to the fact that valence and conduction bond in metal are in overlapped conditioned. Therefore showing zero gap energies

insulators - large band gap energies

insulator has high band gap

semiconductor - Band gap of intermediate energies

semi conductor has gap of intermediate range

while for superconductor cooper pair theory is applied for calculating gap energies.

A point particle of mass m is fixed to the bottom end of a thin wire suspended from a fixed point on the ceiling. The thin wire

natima [27]

Answer:

$T = (m + \frac{M}{L}y)g$

$v = \sqrt{(\frac{mL}{M} + y)g}$

Part b)

$t = 2(\frac{\sqrt{(\frac{mL}{M} + L)g}}{g} - \frac{\sqrt{(\frac{mL}{M})g}}{g})$

Explanation:

Part a)

tension in the wire at any distance "y" from the bottom end of the wire is due to the weight of the suspended part of the wire given by the equation

$T = (m + \frac{M}{L}y)g$

So here we will have speed of the wave is given as

$v = \sqrt{\frac{T}{M/L}}$

now we have

$v = \sqrt{\frac{(m + \frac{M}{L}y)g}{M/L}}$

$v = \sqrt{(\frac{mL}{M} + y)g}$

Part b)

now the time taken by the wave to reach the top is given as

$t = \int \frac{dy}{v}$

$t = \int_0^L \frac{dy}{\sqrt{(\frac{mL}{M} + y)g}}$

$t = 2(\frac{\sqrt{(\frac{mL}{M} + L)g}}{g} - \frac{\sqrt{(\frac{mL}{M})g}}{g})$

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k

adell [148]

Answer:

a) = 10.22 rad/s

b) = 0.35 m

Explanation:

Given

Mass of the particle, m = 1.1 kg

Force constant of the spring, k = 115 N/m

Distance at which the mass is released, d = 0.35 m

According to the differential equation of s Simple Harmonic Motion,

ω² = k / m, where

ω = angular frequency in rad/s

k = force constant in N/m

m = mass in kg

So,

ω² = 115 / 1.1

ω² = 104.55

ω = √104.55

ω = 10.22 rad/s

If y(0) = -0.35 m and we want our A to be positive, then suffice to say,

The value of coefficient A in meters is 0.35 m
