The given statement "protons and neutrons both have positive charge, and electrons have negative charge" is false.

Answer: Option 2

<u>Explanation:</u>

The atoms of all elements are made up of tiny particles that were unknown to the world for many years. With the efforts of wise brains such as J.J. Thomson, Rutherford and Chadwick, it has been concluded that an atom is not the smallest particle and is comprised of three tiny particles’ combination- Protons, Electrons and Neutrons.

The protons have a natural positive charge that attracts the equal but opposite charge towards them and they are electrons. Electrons have a negative charge and revolve around the nucleus of an atom in their constituent orbits.

Neutrons don’t have any charge on them and hence, remain at rest inside the nucleus of atoms. They are actually the flipped iso-spins of protons. The purpose of neutrons in the nucleus is to create a balance between two or more protons so that they can co-exist in the nucleus and it may not scatter.

A musical note has a frequency of 512 Hz. If the wavelength of the note is 0.685 m, what is the speed of the sound of that note?
riadik2000 [5.3K]

Answer:

350.72 m/s

Explanation:

Formula for velocity of wave is;

v = fλ

Where;

v is speed

f is frequency

λ is wavelength

We are given;

f = 512 Hz

λ = 0.685 m

Thus;

v = 512 × 0.685

v = 350.72 m/s

A 3.1 kg ball is thrown straight upward with a speed of 18.2 m/s. Use conservation of energy to calculate the maximum height the
spayn [35]

Answer:

h = 16.9 m

Explanation:

When a ball is thrown upward, its velocity gradually decreases, until it stops for a moment, when it reaches the maximum height, while its height increases. Thus, the law conservation of energy states in this case, that:

Kinetic Energy Lost by Ball = Potential Energy Gained by Ball

(0.5)m(Vf² - Vi²) = mgh

h = (0.5)(Vf² - Vi²)/g

where,

Vf = Final Speed of Ball = 0 m/s (Since, ball stops for a moment at highest point)

Vi = Initial Speed of Ball = 18.2 m/s

g = acceleration due to gravity = - 9.8 m/s² ( negative for upward motion)

h = maximum height the ball can reach = ?

Therefore, using values in the equation, we get:

h = (0.5)[(0 m/s)² - (18.2 m/s)²]/(-9.8 m/s²)

<u>h = 16.9 m</u>

Two identical heavy balls are dropped from the top of the Leaning Tower of Pisa. The second ball is dropped 1 s after the first
Pepsi [2]

As the balls continue to accelerate to the ground,  the distance between them before the first ball hits the ground will increase.

<h3>What is acceleration?</h3>

Acceleration is defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

Two identical heavy balls are dropped from the top of the Leaning Tower of Pisa. The second ball is dropped 1 s after the first ball. The first ball start falling 1s earlier than the second ball. Thus, the acceleration for first ball will be greater than the second ball.

Thus, the distance between them before the first ball hits the ground will increase.
