In this problem we will use the formula: f = c/λ
Wherein: f = frequency
c = speed of wave
λ = wavelength of wave
500 km/h / 200 km = 2.5 Hz
<span>In this problem, speed and the distance between
crests are given. Therefore, all you have to do is to divide the speed by the wavelength
to determine the frequency using the formula provided.</span>
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

A constant is something that is kept the same throughout the course of a experiment. So I would guess C) because they are not doing anything special. If it’s not C then it is A. :)
Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.
Hope that answers the question, have a great day!
