Primarily to survey and map the landscape of Mars for future missions. It also takes core samples and searches for water underground. This is important for many reasons, but most obviously for the upcoming missions to mars and the colonies that follow. Hope this helps?

To practice Problem-Solving Strategy 22.1: Gauss's Law.An infinite cylindrical rod has a uniform volume charge density rho(where

d1i1m1o1n [39]

Answer:

Solution for 3 different cases are given in explanation.

Explanation:

Gauss's Law:

$\int_S E.dA=Q_{encl}/\epsilon_0$

for $r$ :

$E.2\pi rL=\frac{\rho\pi r^2L/\pi r_0^2}{\epsilon_0} \\\\E=\frac{\rho r}{2\pi\epsilon_0 r_0^2}$

for $r=r_0$ :

$E.2\pi r_0L=\frac{\rho\pi r_0^2L}{\epsilon_0} \\\\E=\frac{\rho r_0}{2\epsilon_0}$

for $r>r_0$ :

$E.2\pi rL=\frac{\rho\pi r_0^2L}{\epsilon_0} \\\\E=\frac{\rho r_0^2}{2\epsilon_0 r}$

You illuminate a slit with a width of 0.0549 mm with a light of wavelength 735 nm and observe the resulting diffraction pattern

spayn [35]

Answer:

Explanation:

Given

slit width $d=0.0549\ mm$

wavelength of light $\lambda =735\ nm$

Screen is placed at a distance of $D=2.85\ m$

The angle for the first minima is given by

$\sin \theta _1=\frac{m\lambda }{d}$

for m=1

$\sin \theta _1=\frac{1\times 735\times 10^{-9}}{0.0549\times 10^{-3}}$

$\sin \theta _1=0.0133$

and one half of central maxima is given by

$Y=D\sin \theta _1$

$Y=2.85\times 0.0133$

$Y=0.0381\ m$

Width of central maxima $=2Y$

$Width=0.0762\ m\approx 7.62\ cm$

What are some of the phenotypic plant traits that scientists are investigating? Why do you think these traits were chosen?

vodomira [7]

The term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant's observable characteristics.

<u>Explanation</u>:

Phenotype, any of the measurable features of an organism arising from its genotype association (total genetic inheritance) with the environment. Behaviour, biochemical properties, colour, form, and scale are examples of measurable characteristics.
An allele is another type of one gene. A phenotype triggered by the expression of a gene or group of genes is the external manifestation of a human trait.
A trait is an attribute unique to an organism. The genotype's external expression is called the phénotype.
