Explanation:

Electron volt:

small unit of energy is known as electron Volt it is represented by eV

radiation:

energy and/or mass being ejected from a nucleus in the form of radiation.

Photon:

smallest amount of light  is known as photon.

X-ray

radiation emitted from decelerated electrons are known as X-ray

Planck's constant :

planck's Constant is denoted by h=6.63 x 10^-34 js

Photoelectric effect:

light shining on a metal surface causes electrons to be emitted from the surface this phenomena is known as photoelectric effect.

Uncertainty principle:

According to uncertainty principal exact position and momentum of microscopic particle cannot be determined simultaneously.

De Broglie wave:

wave associated with moving matter is known as De Broglie wave.

best model for light includes both the wave theory and quantum theory

Quanta:

Light travel in the form of packets of energy and each packet of energy is known as photon or quanta.

The conservation of momentum is most closely related to
BartSMP [9]

Answer:

<h2>B) Newton's 2nd law</h2>

Explanation:

<h2>From; force= mass × acceleration </h2><h2> f= m×a </h2><h2>where a(acceleration)= velocity/time</h2><h3> force = mv/t</h3><h3>But momentum(p) = Mass × velocity </h3><h2>hence force =p/t </h2><h3>that is Momentum = force × time ( Newton's 2nd law)</h3>

A rock thrown straight up takes 4.2 s to reach its maximum height what was its initial velocity
liubo4ka [24]

Consider the upward direction of motion as positive and downward direction of motion as negative.

a = acceleration due to gravity in downward direction = - 9.8 \frac{m }{s^{2}}

v₀ = initial velocity of rock in upward direction = ?

v = final velocity of rock at the highest point = 0 \frac{m }{s}

t = time to reach the maximum height = 4.2 sec

Using the kinematics equation

v = v₀ + a t

inserting the values

0 = v₀ + (- 9.8) (4.2)

v₀ = 41.2 \frac{m }{s}

A satellite of mass m completes one revolution around the earth at a constant speed s and radius r.
MAXImum [283]

Answer:

d. The magnitude of the work done by the earth on the satellite is non zero

Explanation:

The work done is equal to the product of the force and the distance moved in the direction of the force, the force and the distance act perpendicular to one another, therefore no work is done in the circular motion of the movement of the earth.
