Sue described two subatomic particles below: Particle P: Non-charged particle
Particle Q: Positively charged particle

Which of the following statements is correct based on the descriptions of each particle?

Particle P is an electron and Particle Q is a proton.
Particle P is a neutron and Particle Q is an electron.
Both particles are inside the nucleus of the atom.
Both particles revolve around the nucleus of the atom.

Both particles are inside the nucleus of the atom

Explanation:

Particle P is a neutron and Particle Q is a proton. Both are inside the atom, while electrons revolve around it.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

girl imma just put my comment here because i need a couple point okurrttt
