The wording of the choices is really unclear. With two resistors in parallel,
here's the situation:
-- The voltage across each resistor is the same as the voltage across
the other one. If the parallel combination is connected to the battery,
then the voltage across each resistor is the full battery voltage.
-- The current through each resistor is (V) / (the resistance of that resistor).
That's the same current as would flow through that resistor if the other one
were not there.
-- As long as the battery or other power supply holds out, neither of these
quantities changes.
Can you match this situation to one of the choices listed ?
It looks to me as if choice 'C' is the one that's most likely
trying to say this.
Answer:
Communication is simply the act of transferring information from one place, person or group to another. Every communication involves (at least) one sender, a message and a recipient. This may sound simple, but communication is actually a very complex subject

Answer:
The 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
Explanation:
The standard temperature at sea level is 15 degrees Celsius. It decreases about 2 degrees C (or 3.5 degrees F) per 1,000 feet of altitude above sea level.
235 meters is equal to 771 feet.
Using the formula below, we can estimate temperature loss due to this change in altitude, that is 771 feet above sea level.
temperature loss = (3.5 x Change in altitude)/1000ft
temperature loss = (3.5 x 771ft)/1000ft = 2.7⁰F, (32 -2.7 = 29.3 ⁰F)
this is equivalent to 1.5⁰C temperature loss.
Thus, the standard temperature of the engineering quadrangle at 235 meters above sea level is 13.5 ⁰C.
Therefore, the 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
Answer:
magnetic field strength is 0.315852 T
Explanation:
Given data
thick = 0.103 mm = 0.103 × 10^-3 m
charge-carrier density = 1.11 × 10^25 m^–3
hall voltage = 3.47 mV = 4.99 × 10^-3 V
current = 2.89 A
to find out
magnetic field strength
solution
we will apply here magnetic field strength formula i.e
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
here put all these value and magnitude of charge electron is 1.6×10^-19 C
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
magnetic field strength = 4.99 × 10^-3 × 1.11 × 10^25 × 1.6×10^-19 × 0.103 × 10^-3 / 2.89
magnetic field strength = 0.912811 / 2.89
magnetic field strength is 0.315852 T
