SPEAR is a storage ring at the Stanford Linear Accelerator which has a circulating beam of electrons that are moving at nearly the speed of light (2.998 108 m/s). If a similar ring is about 92.0 m in diameter and has a 0.40 A beam, how many electrons are in the beam

Answers

Answer 1
Answer:

Answer:

2.4* 10^(12)

Explanation:

We are given that

Speed of light,v=2.998* 10^8 m/s

Diameter of ring,d=92 m

Radius,r=(d)/(2)=(92)/(2)=46 m

Current, I=0.40 A

We have to find the number of electrons in the beam.

We know that

Current,I=(q)/(t)

Where q= ne

e=1.6* 10^(-19) C

Using the formula

0.40=(1.6* 10^(-19)n)/((2\pi r)/(v))

0.40=(1.6* 10^(-19)n* v)/(2\pi r)

0.40=(1.6* 10^(-19)n* 2.998* 10^8)/(2\pi* 46)

n=(0.40* 2\pi* 46)/(1.6* 10^(-19)* 2.998* 10^8)=2.4* 10^(12)

Why the Higg's Boson was only named after Peter Higgs?

Answers

Because the first person who explicitly predicting that theory is Peter Higgs.

There are a group of scientists who worked together to developed the Higgs Boson ttheory such as Jon Botterworth , but the particle finally named after Peter Higgs out of respect since he's the one who 1st explicitly predict it

 

Answer:

He was among the first to propose its existence.

Explanation:

In July of 2012, physicists found it.  This last boson was named the Higgs, after the British physicist Peter Higgs, who was among the first to propose its existence.

A quantity of gas has a volume of 0.20 cubic meter and an absolute temperature of 333 degrees kelvin. When the temperature of the gas is raised to 533 degrees kelvin, what is the new volume of the gas? (Assume that there's no change in pressure.) A. 0.0006 m3
B. 0.2333 m3
C. 0.2146 m3
D. 0.3198 m3

Answers

 pV = n R T => if pressure is constant => p = n R T / V = const. => p / n R = T/ V = const. => T / V = const. T1 = 333 K T2 = 533 K V1 = 0.2 m3 
T1 / V1 = T2 / V2 => V2 = V1 x T2 / V2 = 0.2 x 533 / 333 = 0.32 m^3 answer D is correct

Lightning strikes 16,090 meters away from you.How long does it take the sound of thunder to get to you at 20°C temperature?


with solution and formula<3

Answers

Final answer:

It takes approximately 47 seconds for the sound of thunder to reach you at 20°C temperature.

Explanation:

The time it takes for the sound of thunder to reach you can be determined using the formula:

Time = Distance / Speed

Sound travels at a speed of approximately 343 meters per second at 20°C. Therefore, to calculate the time it takes for the sound to reach you, divide the distance by the speed:

Time = 16,090 meters / 343 meters per second

Time = 46.97 seconds

So, it takes approximately 47 seconds for the sound of thunder to reach you at 20°C temperature.

An electron in a hydrogen atom undergoes a transition from the n = 3 level to the n = 6 level. To accomplish this, energy, in the form of light, must be absorbed by the hydrogen atom. Calculate the energy of the light (in kJ/photon) associated with this transition.

Answers

Answer:1.816* 10^(-19) J

Explanation:

Given

E=(hc)/(\lambda )

E=2.18* 10^(-18)((1)/(n_1^2)-(1)/(n_2^2))

where h=Planck constant

c=speed of light

E=2.18* 10^(-18)((1)/(3^2)-(1)/(6^2))

E=2.18* 10^(-18)* (1)/(12)

E=1.816* 10^(-19) J

Answer:

1.82 × 10⁻¹⁹ J

Explanation:

The Bohr model of the atom states that the energy required to transition between two energy levels is equal to the difference between the inverse squares of the energy levels multiplied by the Rydberg constant:
