Answer:
2744Nm
Explanation:
The gravitational field is conservative. The gravitational force only acts on a vertical direction. Hence, independently of the form of the trajectory, the work done by the gravity against the person demands the calculation of the integral of the force multiplied by the vertical displacement of the person:
![W_g=\int_0^{4}Mgdz=Mg[4]=(70kg)(9.8\frac{m}{s^2})(4m)=2744Nm](https://tex.z-dn.net/?f=W_g%3D%5Cint_0%5E%7B4%7DMgdz%3DMg%5B4%5D%3D%2870kg%29%289.8%5Cfrac%7Bm%7D%7Bs%5E2%7D%29%284m%29%3D2744Nm)
where we have taken that the displacement of the person h=z and df=dz.
hope this helps!!
Explanation:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

Answer:
In a vacuum all light travels the same speed no matter what the wavelength or frequency. Gamma radiation has a smaller wavelength and larger frequency, radio waves a smaller frequency and larger wavelength.
