Niels Bohr created the Atomic theory by combining Rutherford's description of the nucleus and Planck's theory about quanta.

<h3>What is Bohr's atomic theory?</h3>

This was proposed by Neil Bohr and talks about how electrons move in fixed orbitals and not anywhere in between and was able to explain that each orbit has a fixed energy.

He explained the various activities and processes which were happening inside an atom thereby deducing a picture of atomic structure such as the presence of the subatomic particles in the nucleus and how they are involved in a chemical reaction.

The structure was that of a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus which is similar to the planets.

This is therefore the different processes and ways in which Bohr created his atomic theory.

Niels  Bohr created the Atomic theory after studying the way glowing, hot hydrogen that gives off light.

<h3>How did Niels Bohr create the Atomic theory?</h3>

He developed the atomic model after studying the glowing of hot hydrogen that gives off light. When a light bulb is lit, it gives all the different wavelengths of the light. Niels Bohr proposed an atomic theory for the hydrogen atom, which is based on quantum theory. He says in this theory that Electrons move around an orbit of the nucleus , and If the electrons jump from a lower-energy orbit to a higher energy orbit, the energy is released in orbit in the form of radiation.

so we can conclude Niels Bohr created the Atomic theory after studying the way glowing, hot hydrogen that gives off light.

A tennis player swings and hits the ball away. How does the force of the tennis racket affect the motion of the ball
defon

The force of the racket affects the ball's motion because it changes the momentum of the ball.

<h3>Impulse received by the ball</h3>

The impulse received by the ball through the racket affects the motion because it changes the momentum of the ball.

The ball which is initially at rest, will gain momentum after been hit with the racket.

J = ΔP = Ft

where;

  • J is the impulse received by the ball
  • ΔP is change in momentum of the ball
  • F is the applied force
  • t is the time of action

Thus, the force of the racket affects the ball's motion because it changes the momentum of the ball.

Consider a sound wave moving through the air modeled with the equation s(x, t) = 5.00 nm cos(60.00 m−1x − 18.00 ✕ 103 s−1t). Wha
GaryK [48]

Answer:

Shortest time = 58.18 × 10^(-6) s

Explanation:

We are given;

s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t))

Let us set x = 0 as origin.

Now, for us to find the time difference, we need to solve 2 equations which are;

s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t1))

And

s(x,t) = 5.00 nm cos((60.00 m^(−1)x) − (18.00 X 10³ s^(−1)t2))

Now, since the wave starts from maxima at time at t = 0, the required time would be the difference (t2 - t1)

Thus, the solutions are;

t1 = (1/(18 × 10³)) cos^(-1) (2.5/5)

And

t2 = (1/(18 × 10³)) cos^(-1) (-2.5/5)

Angle of the cos function is in radians, thus;

t1 = 58.18 × 10^(-6) s

t2 = 116.36 × 10^(-6) s

So,

Required time = t2 - t1 = (116.36 × 10^(-6) s) - (58.18 × 10^(-6) s) = 58.18 × 10^(-6) s
