Answer:
The force between charges is 
.
Explanation:
The Coulomb force 
between the two charges 
and 
separated by distance 
is given by the equation
where 
is the coulombs constant, and has the value
.
Now in our case
and
,
therefore, the Coulomb force between the charges is
A triangle is just a shape...
Answer:
A
Explanation:
The magnet can always attract other things.
Answer:
10,000 eV
Explanation:
According to the law of conservation of energy, the kinetic energy gained by the electron is equal to its change in electric potential energy:
where:
K is the kinetic energy of the electron
is the magnitude of the charge of the electron
is the potential difference through which the electron has been accelerated
For this electron in the TV, we have
Therefore, the kinetic energy of the electron in electronvolts is
Answer:
α = - 1.883 rev/min²
Explanation:
Given
ωin = 113 rev/min
ωfin = 0 rev/min
t = 1.0 h = 60 min
α = ?
we can use the following equation
ωfin = ωin + α*t ⇒ α = (ωfin - ωin) / t
⇒ α = (0 rev/min - 113 rev/min) / (60 min)
⇒ α = - 1.883 rev/min²
