 - <span>they are always formed by a cation and a anion 

- they transfer electrons rather than shared 

- all are binary ionic compounds are solids 

- they are neutral i.e. no charge</span>

The KE can be solve using the formula:
ke = 0.5 mv^2
where m is the mass of the object
v is the velocity
ke = 0.5 ( 2 kg ) ( 5 m/s)^2
ke = 25 J

the GPE can be solved using the formula:
GPE = mgh
where m is the mass
g is the acceleration due to gravity ( 9.81 m/s^2)
h is the height

GPE = ( 4 kg)(9.81 m/s^2)( 40 m)
GPE = 392.4 J

10.0 grams of water are heated during the preparation of a cup of coffee 1.0x 103 j of the heat are added to the water. which is
nirvana33 [79]

<u>Answer:</u> The final temperature of the coffee is 43.9°C

<u>Explanation:</u>

To calculate the final temperature, we use the equation:

q=mC(T_2-T_1)

where,

q = heat released = 1.0\times 10^3J=1000J

m = mass of water = 10.0 grams

C = specific heat capacity of water = 4.184 J/g°C

T_2 = final temperature = ?

T_1 = initial temperature = 20°C

Putting values in above equation, we get:

1000J=10.0g\times 4.184J/g^oC\times (T_2-20)\\\\T_2=43.9^oC

Hence, the final temperature of the coffee is 43.9°C

If the kinetic and potential energy in a system are equal, then the potential energy increases. What happens as a result?
ZanzabumX [31]

Answer: As a result an increase in kinetic energy also happens.

Explanation:

Potential energy is the energy occupied by an object or substance due to its position.

Kinetic energy is the energy occupied by an object of substance due to its motion.

If the kinetic and potential energy in a system are equal and then an increase in potential energy will occur.

As a  result, there will also occur an increase in kinetic energy also.

Thus, we can conclude that as a result an increase in kinetic energy also happens.

In the 17th century, Newton proposed that light was a stream of particles. The wave-particle debate continued for over 250 years

Light as a wave

  • Young's Double Slit Experiment.
  • Davisson-Germer Experiment

Light as a particle

  • Einsteins Photoelectric Effect Phenomenon
  • Diffraction Phenomenon of Particles

<h2>Define the following terms:-</h2><h3> 1)Photoelectric Effect</h3>

Electrons are released when a material is exposed to electromagnetic radiation, such as light, and this is known as the photoelectric effect. These electrons are referred to as photoelectrons.

<h3>2)Diffraction </h3>

When a wave hits a wall or an opening, several phenomena known as diffraction take place. It is described as the interference or bending of waves through an aperture into the region of the geometric shadow cast by the obstruction or aperture.

<h3>3)Davisson-Germer Experiment</h3>

In the Davisson-Germer experiment, conducted by Clinton Davisson and Lester Germer between 1923 and 1927 at Western Electric (later Bell Labs), electrons scattered by a nickel-metal crystal's surface showed a diffraction pattern. This was an experimental turning point in the development of quantum mechanics and supported the wave-particle duality concept first put forth by Louis de Broglie in 1924.

<h3>4)Young's Double Slit Experiment.</h3>

One of the most significant physics experiments was Young's Double Slit experiment. Thomas Young directed it in 1801. Despite the fact that Huygens' experiment had demonstrated that light has a wave character, the light at the time was still thought of as a beam of particles due to Newton's renown.
