To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by
Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And
Therefore using the values given we can find the velocity through,
Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1
Therefore the cars goes to 145.3m/s
Answer:
a) , b)
Explanation:
a) The magnetic force experimented by a particle has the following vectorial form:
The charge of the electron is equal to . Then, cross product can be solved by using determinants:
The magnetic force is:
b) The charge of the proton is equal to . Then, cross product has the following determinant:
The magnetic force is:
Resistance can be calculated by Ohm's law
As per ohm's law we will have
here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have
So resistance of the bulb is 22 ohm.
