Two microwave signals of nearly equal wavelengths can generate a beat frequency if both are directed onto the same microwave detector. In an experiment, the beat frequency is 170MHz . One microwave generator is set to emit microwaves with a wavelength of 1.410cm.

If the second generator emits the longer wavelength, what is that wavelength?

Solutions

Expert Solution

Velocity of wave = veolicty of light = 3*10^8 m/s

So frequency of wave of wavelength 1.41 cm = velocity / wavelength = (3*10^8) /(1.41*10^-2) = 2.127659 *10^10 Hz

So , the second frequency is lower,

second frequency = ( 2.127659*10^10) - beat frequency = ( 2.127659*10^10) -(170*10^6) = 2.110659 *10^10 Hz

So, wavelength of second wave = velocity / frequency = (3*10^8)/(2.110659 *10^10) = 1.4213*10^-2 m = 1.4213 cm is the answer

Meiosis is a process that can generate nearly infinite variation from a single source of genes, even before the additional diversity created by fertilization. There are two main processes that occur during meiosis to generate diversity. Describe each of these processes, referencing where in the meiotic cycle they occur and how they contribute to genetic diversity in the gametes. Format your answer into parts (i) and (ii) for the two processes.

Question: A cell can initiate both pro- and anti- apoptotic signals in response to a stimuli. Given each scenario, choose the most likely protein to counteract the “cell death signal” and save the cell. To save the cell you must choose the best strategy (Best = most direct, so if we disrupt A we should fix A or possibly B instead of trying to fix D.) Pick a strategy for the scenario: 1.Activated Caspase 9 2.Activated Bax and Bak 3.Release...
