Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform,
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :
n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.
Answer:
the answer of this question is iii .
if the answer is wrong so sorry
Answer: The force you exert on the handle of a screen door as you open the door is on the order of 10 N. The force exerted by a honeybee as it lands on a flower is on the order of 0.001 N. The thrust force produced by the engines of a passenger jet as it takes off is on the order of 100,000 N. The weight of the largest aircraft carriers is on the order of 1,000,000,000 N.
Explanation:
In the first case, force made by hands and arms movement is in the range of 1 or 10N. In the second case, we are talking of a honeybee, an insect that weighs grames. The third case is the force required to make a plane take off (it is %10 of the thrust force of a plain with a weight of 300000N to 1000000N). In the last case, we are talking of the largest aircraft carriers, steel monsters that weight thousand of tons.
Answer:
Q' = 3.21*10^{-5}C
Explanation:
To find the new magnitude of the charge you take into account that the voltage of the this capacitor is given by:
Q: total charge
d: distance between parallel plates
A: area of the plates
εr: dielectric constant
εo = dielectric permittivity of vacuum
for the case of the air εr = 1, then,
(1)
When a dielectric material is placed in between the plates, you have, for the same voltage, and for a different charge:
(2)
you equal the equation (1) and (2) and obtain:
by replacing you obtain:
