E = mgh
= (2)(9.8)(4)
= 78.4 Joules
Answer:
<em>1988.05 rad/s^2</em>
<em></em>
Explanation:
The angular speed of the optical disk ω = 998.0 rad/s
the time taken to come to rest t = 0.502 s
The magnitude of the average angular acceleration ∝ = ω/t
∝ = 998.0/0.502 = <em>1988.05 rad/s^2</em>
Force of attraction between one atom and another within a compound formed by sharing of electrons or the loss and gain of electrons this is a bond

if i can pass, you can too :)
Explanation:
its super inspiring cuz im a dumbass
Answer:
the sign of these carriers is POSITIVE
Explanation:
In the effect, he found the charge carriers that were subjected to two forces, one electric and the other magnetic.
F = F_e + F_m = q E + q v x B
bold indicates vectors
The electric field goes to the east, therefore the current also has this direction, the vector product of the velocity of the charge carriers towards the east and the magnetic field upwards, using the right hand rule a magnetic force is created towards the north if the carriers are positive.
In the exercise they indicate that the north side has a higher potential than the south side, therefore there must be an accumulation of carriers on this side that create an electric field (Hall) that is put to the magnetic force until reaching equilibrium when the total force is zero.
Therefore the sign of these carriers is POSITIVE
