An Alpha particle moving in north direction give reasons​

Physics
2 answers:
Mazyrski [523]3 years ago
7 0

Your question has been heard loud and clear.

An alpha particle , can move in any direction randomly. But with a magnetic field , we can deflect the alpha particle in any direction we want.

So , the magnetic field must be placed to the west of the alpha particle , so that the particle gets deflected and moves towards the north direction.

Thank you.

taurus [48]

Answer:  

a. Speed = 1.6 m/s  

b. Amplitude = 0.3 m  

c. Speed = 1.6 m/s  

Amplitude = 0.15 m  

Explanation:  

a.  

The frequency of the wave must be equal to the reciprocal of the time taken by the boat to move from the highest point to the highest point again. This time will be twice the value of the time taken to travel from the highest point to the lowest point:

frequency = \frac{1}{2(2\ s)} = 0.25 Hz  

The wavelength of the wave is the distance between consecutive crests of the wave. Therefore,  

Wavelength = 6.4 m  

Now, the speed of the wave is given as:  

Speed = (Frequency)(Wavelength)  

Speed = (0.25 Hz)(6.4 m)  

<u>Speed = 1.6 m/s</u>

b.  

Amplitude is the distance between the mean position of the wave and the extreme position. Hence, it will be half the distance between the highest and lowest point:  

Amplitude = (0.5)(0.6 m)  

<u>Amplitude = 0.3 m</u>  

c.  

frequency = \frac{1}{2(2\ s)} = 0.25 Hz  

Speed = (Frequency)(Wavelength)  

Speed = (0.25 Hz)(6.4 m)  

<u>Speed = 1.6 m/s</u>  

Amplitude = (0.5)(0.3 m)

<u>Amplitude = 0.15 m</u>

Katena32 [7]

Answer:

Conditions that result in the emission of electrons from a conductor:

Heating the conductor to a suitable temperature

Exposing the conductor to a strong light

Subjecting the conductor to a very high applied voltage

Subjecting the conductor to high-speed electrons from another source

Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.
