Answer:
8.66 nano seconds
Explanation:
speed of k mesons ( v ) = c m/s
Distance between counters ( d ) = 9.00 m
number of countable electrical pulses = 1000 counts in first counter and 250 in second counter
time of travel = d / v = 18 / secs
Next write the decay of particles in lab frame
finally calculate the half life of Meson in its own frame
( t 1/2) of meson in its own frame = 8.66 n-secs
attached below is a detailed solution
Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example
answer : a) 14 ohms b) 0.86 amps c) 10.32 V
Explanation:
Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms
Voltage source = 12V
<u>Assuming that the Resistors are in series </u>
<u>a) Determine Total resistance </u>
Req = R1 + R2 + R3
= 3 + 4 + 5 = 14 ohms
<u>b) Total current </u>
Ieq = V / Req
= 12 / 14 = 0.86 amps
<u>c) The Total Voltage over the entire system </u>
Vt = ∑ Voltage drops
= ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )
= 10.32 V
