Answer:
(a). The speed of electron is
.
(b). The radius of electron is 
Explanation:
Given that,
Length = 2.5 cm
Distance = 6.0 mm
Magnetic field = 2.1 T
Potential difference = 700 V
(a). We need to calculate the electron's speed
Using formula of speed

Put the value into the formula



(b). We need to calculate the radius of electron
Using formula of centripetal force


Where,
m = mass of electron
v = speed of electron
r = radius
q = charge of electron
B = magnetic field
Put the value into the formula



Hence, (a). The speed of electron is
.
(b). The radius of electron is 4.2 cm
Answer:
There are four main ways of doing that :-
- Velocity
- Acceleration
- Momentum
- Kinetic energy
Hope it helps!
Answer:pretty sure its mitochondria
Explanation:
The power source voltage remains the same in a parallel circuit,
And we'll have equal current in both lines
<h3>Kirchhoff's junction rule</h3>
Generally, Kirchhoff's junction rule states that when there is current flow at any junction of a circuit, the total sum of this current rushing into the junction amount to the same amount of current out of the Node.
Therefore, when the parallel circuit has two branches
i=i1+12
Since we have an equal resistor therefore we'll have equal current in both lines i.e i1=i2
And Voltage remains the same in a parallel circuit
