Why do sound engineers use spongy materials in the walls? (1 point)
mihalych1998 [28]

Answer:

o to increase the frequency of sound waves. It increases the sound waves to a level of frequency that humans cannot hear so you won't be able to hear many things though the wall other then low noises like pounding.

Explanation:

I am in construction class as well as a student teacher for other construction type programs trust me :D

What is the relation between acceleration due to gravity and radius of the earth? ​
emmasim [6.3K]

Answer:

As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.

Formula: g = GM/r2

Dimensional Formula: M0L1T-2

Values of g in SI: 9.806 ms-2

A charge partides round a 1 m radius circular particle accelerator at nearly the speed of light. Find : (a) The period (b) The c
Scrat [10]

Explanation:

It is given that,

Radius of circular particle accelerator, r = 1 m

The distance covered by the particle is equal to the circumference of the circular path, d = 2πr

d = 2π × 1 m

(a) The speed of satellite is given by total distance divided by total time taken as :

speed=\dfrac{distance}{time}

Let t is the period of the particle.

t=\dfrac{d}{s}

d = distance covered

s = speed of particle

It is given that the charged particle is moving nearly with the speed of light

t=\dfrac{d}{c}

t=\dfrac{2\pi\times 1\ m}{3\times 10^8\ m/s}

t=2.09\times 10^{-8}\ s

(b) On the circular path, the centripetal acceleration is given by :

a=\dfrac{c^2}{r}

a=\dfrac{(3\times 10^8\ m/s)^2}{1\ m}

a=9\times 10^{16}\ m/s^2

Hence, this is the required solution.

Suppose an electron is trapped within a small region and the uncertainty in its position is 24. 0 x 10-15 m. what is the minimum
sergeinik [125]

The minimum uncertainty in the electron's momentum is

Δp = 2.2822 \times 10 {}^{ - 20} kg/ms

Given:

Uncertainty in position (ΔX)

= 24 \times 10 {}^{ - 15}m

planck's constant (h)

= 6.26 \times 10 {}^{ - 34} js

To find:

uncertainty in momentum (Δp)

Δx.Δph/4π

24 \times 10 {}^{ - 15} .Δp =  \frac{6.26 \times 10 {}^{ - 34} }{4 \times  \frac{22}{7} }

24 \times 10 {}^{ - 15}. Δp =  \frac{6.26 \times 10 {}^{ - 34} \times 7 }{8}

Δp =  \frac{43.82 \times 10 {}^{ - 34} }{8 \times 24 \times 10 {}^{ - 15} }

Δp =  \frac{43.82 \times 10 {}^{ - 34}  \times 10 {}^{ 15} }{192}

Δp =  \frac{4382 \times 10 {}^{ - 21} }{192}

Δp =22.822 \times 10 {}^{ - 21}

Δp = 2.2822  \times 10 {}^{ - 20} kg/ms

=

K

+

U

Where

K

is the kinetic energy of the object and

U

is the potential energy of the object. The carriage, sitting motionless at the top of the hill, has only potential energy in the form of gravitational potential energy.

Gravitational potential energy is given by:

U

Where

m

is the mass of the object,

g

is the gravitational acceleration constant, and

h

is the height of the object above some specific reference point, in this case the ground
