Base in your questions that ask what cause the bright lines seen in the emission spectrum and i think the best answer to that is the H2 gas is used when protons was heated so the electron absorb all the photons and get exited and resulted by given of a light.

A 240 cm length of string has a mass of 2.5 g. It is stretched with a tension of 8.0 N between fixed supports. (a) What is the w

kotykmax [81]

Answer:

a.87.6 m/s

b.18.25 Hz

Explanation:

the equation for the wave speed is expressed as

$v=\sqrt{\frac{Tl}{m}}\\$

where v is the speed,

T is the tension in Newton

l is the length

and m is the mass

Now since

$T=8.0N\\m=2.5g=0.0025kg\\l= 240cm=2.40cm\\$

by substituting values into the equation, we have

$v=\sqrt{\frac{8*2.40}{0.0025} } \\v=87.6m/s\\$

b. the expression for the frequency is giving as

$Frequency,f=\frac{v}{2l} \\f=\frac{87.6}{2*2.40} \\f=18.25Hz\\$ .

Note we 2L as the wavelength because we solving for the fundamental frequency as stated in the question.

A 762 kg car experiences a braking force of 9045 N and skids to a stop in 4.3 seconds. What is the speed of the car just before

PilotLPTM [1.2K]

Answer:

The solution for this problem is:

We will be using the formula for force which is F = ma

=>10,000 = 2000 * a

but we need to solve for acceleration so divide both sides by 2000, we will get:

=>a = 5 m/s^2

Let the initial velocity was u m/s

=>By v = u - at

=>0 = u - 5 x 6

Since acceleration is constant the velocity can be computed by multiplying the acceleration by 6 seconds.

=>u = 30 m/s
