Answer:
Average speed = 0.35 m/s
Explanation:
Given the following data;
Distance = 1.3 Km
Time = 62 minutes
To find the average speed in m/s;
First of all, we would convert the quantities to their standard unit (S.I) of measurement;
Conversion:
1.3 kilometres to meters = 1.3 * 1000 = 1300 meters
For time;
1 minute = 60 seconds
62 minutes = X
Cross-multiplying, we have;
X = 62 * 60
X = 3720 seconds
Now, we can calculate the average speed in m/s using the formula;
Average speed = 0.35 m/s
Answer:
the speed of electron is 4.42 x 10⁶ m/s
the speed of proton is 2406.7 m/s
Explanation:
Given;
electric field strength, E = 478 N/C
charge of the particles, Q = 1.6 x 10⁻¹⁹ C
mass of proton, Mp = 1.673 x 10⁻²⁷ kg
mass of electron Me = 9.11 x 10⁻³¹ kg
time of motion, t = 54.2 ns = 54.2 x 10⁻⁹ s
The magnitude of charge experienced by the particles is calculated as;
F = EQ
F = 478 x 1.6 x 10⁻¹⁹
F = 7.648 x 10⁻¹⁷ N
The speed of the particles is calculated as;
