The galaxy ngc 4414 is moving away from us at 7.16* 10^5 m/s. By how much will the frequency of the 6.91*10^14 Hz hydrogen line be shifted in the galaxy's spectrum?

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.

What is the wavelength of an earthquake wave if it has a speed of 8 km/s and a frequency of 3 hz?
