Answer:
The wavelength is
The frequency is
Explanation:
Given that,
Distance between slits d= 0.044 mm
Distance between fringe and center of the pattern y= 8.1 cm
Distance between slits and fringes D = 6.40 m
We need to calculate the wavelength
For constructive interference
Put the value into the formula
We need to calculate the frequency
Using formula of frequency
Hence, The wavelength is
The frequency is
The nucleus is the center of the atom made up of protons and neutrons with an overall positive charge. this is where the majority of the atom's mass is.
the electron cloud is the energy levels filled with electrons orbiting the nucleus, there is hardly any mass and it has an overall negative charge equal to that of the nucleus it is orbiting if it is part of a neutral atom.

The IRB at the university will decide whether her study meets ethical guidelines before it is initiated. The importance of these codes of conduct is to safeguard research participants, the status of psychology and the researchers or psychologists themselves. Moral issues hardly yield a simple, unequivocal, right or wrong answer. It is consequently often a matter of judgment whether the research is justified or not. For instance, it might be that a study roots psychological or physical uneasiness to participants, maybe they agonize pain or maybe even come to solemn harm.
Answer:
Explanation:
F = ma and
We have F, we have m, but in order to solve for v, we need a.
30.0 = 3.00a so
a = 10.0 m/s/s. Plug that in for a in the second equation and solve for v:
so
v = 10.0(3.00) so
v = 30.0 m/s
