Answer:
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Explanation:
Given;
wavelength = 6.33 x 10^-7 m
Speed of light v = 3.0 x 10^8 m/s.
Frequency of the laser light f
= speed of light/wavelength
Substituting the given values;
f = 3.0 x 10^8 m/s ÷ 6.33 x 10^-7 m
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Traveling wave is a wave that is not confined to the space along medium.
traveling wave is a wave that travels along the medium causing disturbance. instead of vibrating at the same place, the particles actually move in the direction of wave. one common example of such type of wave is ocean waves.
The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.
ANOTHER RUNNING DOG
Explanation:
In the given question it is to find a suitable reference point to describe the motion of dog. Here I could suggest that it is better to compare the dog with another running dog to create the relative speed difference to get a reliable motion variation.
Because the motion of dog is in the linear with respect to the another dog and to the acceleration produced by the dog in the required interval is easy to calculate with respect to another dog which is already in motion.
Hence, I suggest that Motion of dog can be analysed better by analyse the motion variation of dog with another dog running.
<span>THIS IS A GAS PHASE REACTION AND WE ARE GIVE PARTIAL PRESSURES . I WRITE IN TERMS OF P RATHER THAN CONCENTRATION :
lnPso2cl12=-kt+lnPso2cl1
initial partial pressure Pso2cl12 the rate constant k and the time t
lnPso2cl12=(4.5*10-2*s-1)*65*s+ln (375)
so lnPso2cl12=3.002
we take the base e antilog:
lnPso2cl12=e3.002
Pso2cl12=20 torr
we use the integrated first order rate
lnPso2cl12=3.002=k*t+ lnPso2cl12=3.002
we use the same rate constant and initial pressure
k=4.5*10-2*s-1
Pso2cl12=375
Pso2cl12=1* so2cl12
Pso2cl12=37.5 torr
subtract in Pso2cl12 grom both side
lnPso2cl12- lnPso2cl12=-kt
ln(x)-ln(y)=ln (x/y)
ln (Pso2cl12/Pso2cl20)=-kt
we get t
-1/k*ln(Pso2cl12/Pso2cl20)=t
t=51 s</span>
