Answer:

B. Nuclear fusion

Explanation:

- Nuclear fusion is the process in which small nuclei (such as hydrogen) fuse together into heavier nuclei (for example, helium). In such process, the final mass of the product is less than the sum of the masses of the initial nuclei, therefore the mass which 'disappeared' has been converted into energy, according to Einstein's equation:

E=\Delta m c^2

where

\Delta m is the difference of mass between products and reactants

c is the speed of light

Because c is a very large value (c=3.0\cdot 10^8 m/s), the amount of energy released during nuclear fusion is very huge, even for very small masses. This is the process that occurs inside the core of a star, and because of that, stars are able to produce very huge amounts of energy.

What did Thomson contribute to the model of atom
Ganezh [65]
<h3><u>Answer;</u></h3>

<em>Electrons </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Thomson contributed to the model of an atom by discovery of </u></em><em><u>electrons </u></em><em><u>and thus proving the existence of sub-atomic particles in an atom. </u></em>
  • <u><em>Thomson used cathode ray tube, and demonstrated that cathode rays were negatively charged.</em></u> According to his model normally known as the plum pudding in which he stated that an atom is composed of electrons as subatomic particles that are surrounded by positive charges to balance the electrons.

The sound produced by the loudspeaker in the drawing has a frequency of 11999 Hz and arrives at the microphone via two different
const2013 [10]

The speed at which sound travels through the gas in the tube is 719.94m/s

<u>Explanation:</u>

Given:

Frequency, f = 11999Hz

Wavelength, λ = 0.03m

Velocity, v = ?

Sound speed in the tube is calculated by multiplying the frequency v by the wavelength λ.

As the sound loudness changed from a maximum to a minimum, then we know the sound interference in the case changed from constructive interference (the two sound waves are in phase, i.e. peaks are in a line with peaks and so the troughs), to a destructive interference (peaks coinciding with troughs). The least distance change required to cause such a change is a half wavelength distance, so:

λ/2 = 0.03/2

 λ  = 0.06m

We know,

v = λf

v = 0.06 X 11999Hz

v = 719.94m/s

Therefore, the speed at which sound travels through the gas in the tube is 719.94m/s
