Answer: Please find the answer in the explanation
Explanation:
The question goes thus :
What happens to the charged electroscope when a conductor is moved between its plastic sheets, and why?
When a conductor is moved between its plastic sheets of a charged electroscope, the divergence between the brass plate and the gold leaf will decrease.
And why ?
Because of the unlike charges or neutral uncharged charges between the conductor and the plastic Sheets.
Your answer is B :) because well the conditions are harsh.
Answer:
The angular velocity of the wheel in terms of d, F, and I is, ω = d/t (F/I α) s⁻¹
Explanation:
Given,
The angular velocity ω
The displacement d
The magnitude of the applied force, F
The moment of inertia of the wheel I = mr²
The angular velocity can be written as
ω = v /r
where,
v - linear velocity
r - radius of the wheel
ω = d/t (1/r) (∵ v = d /t)
The force can be written as,
F = m a
= m α r (∵ a = α r)
Multiplying both sides by r
F r = m r² α
F r = I α (∵ I = mr²)
r = I α / F
Substituting in the above equation for ω
ω = d/t (F/I α) s⁻¹
Hence, the angular velocity of the wheel in terms of d, F, and I is, ω = d/t (F/I α) s⁻¹
Fnet = m x a
= 65kg x 0.3m/s^2
= 19.5N
This is assuming that there is no friction or other external forces!
PV/T =C
P.V1/T = 1/2P.V2/3/4T
V1= 4V2/6
V2/V1 = 6/4 =3/2
