c) 9.8m/s
Explanation:
Oct 27, 2015 - In The Martian, astronaut Mark Watney and his crewmates onboard ... is grossly unqualified to challenge the science behind The Martian. ... of Space on the Law of the Sea, that Treaty has thus far been signed by only a handful of nations, none of which have their own ability to launch astronauts into space ...
Answer:
(a)
(b)
Explanation:
Parameter given:
Electric field, E =
(a) Electric force is given (in terms of electric field) as a product of electric charge and electric field.
Mathematically:
Electric charge, q, of an electron =
(b) This electrostatic force causes the electron to accelerate with an equivalent force:
F = -ma
where m = mass of an electron
a = acceleration of electron
(Note: the force is negative cos the direction of the force is opposite the direction of the electron)
Therefore:
Mass, m, of an electron =
=>
The acceleration of the electron is
Complete Question
Find the ratio of intensities in 4 different sets of red to violet spectral satellites in Raman scattering spectra of CCl4 molecules at T=27C temperature if corresponding resonant infrared frequencies (equivalent to frequencies of nuclei vibrations) of CCl4 molecule are 217, 315, 457 and 774 cm-1 . (Note: Wavenumber N in cm-1 is defined as )
Answer:
The ratio of intensities is
Explanation:
From the question we are told that
The number of sets of satellite is
The temperature is
The resonant infrared frequencies are
From the question we see that the wave number also has a unit of hence the value of the wave numbers of the molecule are
Generally intensity is mathematically represented as
Here we see that I varies inversely with wavelength i,.e
From the question we are told that the wave number is mathematically represented as
Therefore
This implies that the ratio of intensity in first set to that of second set to that of third set to that of fourth set is equal to the ratio of the wavenumber in the first set to that of the second set to that of third set to that of fourth
This is mathematically represented as
Substituting values
Choice (3) would be one of the objects because when its stretching its waiting to release the energy. Then choice (1) would be the other object because when it rolls the energy stored in the ball would be released when stopped. Therefore there storing the energy until released.
