✿ Transpiration is the process by which water is carried through plants from roots and release water vapor through their leaves.
✿ Cutting down trees can decrease the amount of water vapor entering the air through the processes of <u>Transpiration</u>
Answer:
t = 23.9nS
Explanation:
given :
Area A= 10 cm by 2 cm => 2 x 10^-2m x 10 x 10^-2m
distance d= 1mm=> 0.001
resistor R= 975 ohm
Capacitance can be calculated through the following formula,
C = (ε0 x A )/d
C = (8.85 x 10^-12 x (2 x 10^-2 x 10 x 10^-2))/0.001
C = 17.7 x 10^-12 (pico 'p' = 10^-12)
C = 17.7pF
the voltage between two plates is related to time, There we use the following formula of the final voltage
Vc = Vx (1-e^-(t/CR))
75 = 100 x (1-e^-(t/CR))
75/100 = (1-e^-(t/CR))
.75 = (1-e^-(t/CR))
.75 -1 = -e^-(t/CR)
-0.25 = -e^-(t/CR) --->(cancelling out the negative sign)
e^-(t/CR) = 0.25
in order to remove the exponent, take logs on both sides
-t/CR = ln (0.25)
t/CR = -ln(0.25)
t = -CR x ln (0.25)
t = -(17.7 x 10^-12 x 975) x (-1.38629)
t = 23.9 x
t = 23.9ns
Thus, it took 23.9ns for the potential difference between the deflection plates to reach 75 volts
Answer:
Magnetic poles
Explanation:
Magnetic poles are the regions where the magnet's force is strongest, one is the north pole and one is the south pole.
Answer:
Explanation:
As we know that current density is ratio of current and area of the crossection
now we have
so the current through the wire is given as
now we have
here we have
now plug in the values in above equation
now we have
now plug in both limits as mentioned
here R = 2.11 mm
Explanation:
1 mega Hertz = 1000000 hertz
