A.The hiker had an easy, level trail from 11:00-12:00 and was able to travel the fastest during that time period.---> may be because this was indeed fastest stage
b.The hiker got tired and walked the slowest from 1:00-2:00.---> no, because this was not the slowest stage
c.The hiker stopped for lunch from 11:00-12:00 and that slowed him down.---> no because this was the fastest stage
d.The hiker ended up in the same place that he started.---> no, because the hiker walked more toward east than toward west and more toward south than toward north.
Answer: option a)
The frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
so the wavlength
l = v / f
where f is the frequency
v iss the linear speed
l is the wavelength
l = ( 5100 m/s ) / ( 2.2 Mhz ) ( 10^6 hz / 1 Mhz )
f = 0.0023 m
f = 2.3 mm
What Is A Molecule? B) NaCi
Answer:
The probability is 0.2222
Explanation:
By the rule of multiplication, we know that there are 27 ways to ride the roller coaster 3 times. This is calculated as:
<u> 3 </u> * <u> 3 </u>* <u> 3 </u>= 27
1st ride 2nd ride 3rd ride
Because there are 3 cars for the first ride, 3 cars for the second ride and 3 cars for the third ride.
On the other hand, there are 6 ways to ride the roller coaster 3 times and ride in each of the 3 cars. This is calculated as:
<u> 3 </u> * <u> 2 </u>* <u> 1 </u>= 6
1st ride 2nd ride 3rd ride
Because, on the first ride, the passenger can choose any of the 3 cars, then for the second ride he can choose any of the 2 cars that he doesn't choose on the first ride and for the third ride he can choose 1 car.
Finally, the probability is calculated as a division of:

Concepts and reason
The concept to solve this problem is that if a capacitor is connected in a RC circuit then it allows the flow of charge through circuit only till it gets fully charged. Once the capacitor is charged it will not allow any charge or current to flow.
Opposite is the case with inductor in the RL circuit. According to Faraday's law an inductor develops an emf to oppose the voltage applied but once the flux change stops then the inductor behaves just like a normal wire as if no inductor is there.
In attached figure, resistor is connected in series to the capacitor.
As we considered the voltage across the capacitor and the voltage across the source.
Voltage across a resistor In RC circuit.
Voltage across a resistor In RL circuit.
