Answer: Artificial Selection

Explanation: Artificial Selection is described as the identification of desirable traits in both plants and animals, then enhance them, so that those traits can be manifested in future generations.

This is the scope behind cross breeding of plants and animals and this have largely been used in agricultural sector to improve input (such as disease-resistant seeds) and other biotechnological settings.

Darwin's described artificial selection as the human form of natural selection.

What factors influence the speed of a wave?
fiasKO [112]

Answer: A medium is any substance or region through which a wave is transmitted. The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).

Which graph represents the solution set of the system of inequalities?<br><br> {−2x+y≤4y&gt;x+2
Jet001 [13]

Answer:

The fourth graph is the answer

Explanation:

We have inequalities

-2x+y\leq 4      \rightarrow y\leq 2x+4

y>x+2

For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of y>x+2 and below the graph of y\leq 2x+4. The shaded region in the fourth graph satisfies these conditions.

<em>Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region. </em>

P.S: the graph of the inequality y>x+2  is dashed because   y is "greater than" and not "equal to" x+2, so this indicates that the values on the line y=x+2 are not included. And the graph of the inequality y\leq 2x+4 is a solid line because y is "less than or equal to" 2x+4, so we are including the values on the line y=2x+4, and that's why it's solid.

During a hard drive crash the read/write head scrapes against the disk with a coefficient of kinetic friction of µk and normal f
Alex_Xolod [135]

Answer:

 α = \frac{2 \mu \  N}{m \ r}

Explanation:

For this exercise we use Newton's equation for rotational motion

           ∑ τ = I α

the troque is

           α = Fr .r

the moment of inertia of a cylinder is

           I = ½ m r²

we substitute

         fr r = (½ m r²) α

the expression friction is

         fr = μ N

we substitute

         μ N r = ½ m r² α

       

         α = \frac{2 \mu \  N}{m \ r}

A Ferris wheel with a 15-m radius makes three complete revolutions in one minute about its horizontal axis. What is the magnitud
Kay [80]

Answer:

1.48 m/s^2, upward

Explanation:

The passenger on the wheel experiences a centripetal acceleration, which is the one that keeps him in a circular motion.

The direction of this acceleration is always towards the centre of the circular trajectory: so when the passenger is at the lowest point of the ride, the acceleration is upward.

Concerning the magnitude, it is given by

a=\omega^2 r

where

\omega is the angular velocity

r = 15 m is the radius

We need to find the angular velocity; we know that the wheel completes 3 revolutions in one minute. Each revolution corresponds to an angle of 2\pi rad, so the total angular displacement is

\theta = 3 \cdot 2\pi = 6\pi rad

And the time is

t = 1 min = 60 s

So the angular velocity is

\omega = \frac{6\pi}{60 s}=0.314 rad/s

And substituting into the equation of the acceleration,

a=(0.314)^2(15)=1.48 m/s^2
