Choose "extinct" if the species is extinct and "endangered" if the species is endangered. Sixty years ago, as few as 20 whooping cranes were left on earth. Now, thanks to conservation efforts, there are more than 300 whooping cranes in the wild.

A.extinct

B.endangered

Answers

Answer 1

Answer: The species is actually endangered and not extinct because there are only 20 species left. Extinct actually means that there would be no species left and so it an incorrect option. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer has helped you.

Answer 2

Answer:

Answer:

B.endangered

Explanation:

Choose "extinct" if the species is extinct and "endangered" if the species is endangered.

Sixty years ago, as few as 20 whooping cranes were left on earth. Now, thanks to conservation efforts, there are more than 300 whooping cranes in the wild.

A.extinct

B.endangered

if there are 20 whooping cranes sixty years ago, and then we have more than 300 today. then it means that the species are endangered

I will go with B

An extinct species no longer exist because there are no offsprings of the parent specie which can give birth to more subspecies .

species no longer exist anywhere on Earth, and once gone they are gone ... on International Trade In Endangered Species like Wild Fauna and Flora (CITES). .... in 1975; the species now numbers more than 1, 000 animals .... whooping cranes, this approach fails to protect most endangered species

Endangered means that the existence is threatened by some human activities, prevailing conditions in the environment or the host it feeds on to survive no longer exists within it reach, hence its survival is at stake

What is the difference between magnetic field and magnetic flux

Answers

Explanation:

The region around a moving charge in which it experience a force is called magnetic field. The force is called magnetic force. The force experienced due to moving charge is given by :

$F=q(v* B)$

q is the charged particle

v is the speed of particle

B is the magnetic field

The number of magnetic field lines passing through any surface is called magnetic flux. The formula used to find the magnetic flux is given by :

$\phi=B.A$

$\phi=BA\ cos\theta$

Hence, this is the required solution.

A body moving with a velocity of 20m/s begins to accelerate at 3 m/s 2 . How far does the body move in 3 seconds

Answers

Given v_in = 20 m/s and a = 3 m/s2, assuming that the bodymoves at constant acceleration, the motion is modeled by the equation:

s(t) = (v_in)t + (1/2)a(t^2)

where s(t) is the distance traveled

substituting the given,

s(t) = 20t + (3/2)(t^2)

at t = 3

s(t) = 20(3) + (3/2)(3)^2

If the overall magnification of a series of two lenses is 30x, and one lens magnifies 5x, what is the magnification of the other lens? Calculate the total magnification if the 5x lens is replaced by a 7x lens

Answers

Answer:

Explanation:

Given

Overall magnification $M=30 x$

One lens magnification is $5 x$

suppose the magnification of other lens is $y$

A compound lens is made up of series of lenses either of same or of different magnification so

$y$ is given by

$y=(30 x)/(5 x)=6 x$

If $5 x$ lens is replaced by $7 x$ lens then total magnification is

$7 x* 6 x=42 x$

Final answer:

The second lens has a magnification of 6x. If the 5x lens is replaced by a 7x lens, the new total magnification would be 42x.

Explanation:

To find the magnification of the second lens, we need to know that the overall magnification of a system is the product of the individual magnifications of its elements. If the overall magnification is 30x and one lens magnifies 5x, the magnification of the other lens can be calculated by dividing 30x by 5x, giving us a magnification of 6x for the other lens.

If the 5x lens is replaced by a 7x lens, we can calculate the new overall magnification by multiplying the magnification of the two lenses together. So, 6x (from the other unchanged lens) multiplied by 7x gives us an overall magnification of 42x.

A wave oscillates 50 times per second. What is its frequency?

Answers

Answer: The frequency of the wave is 0.02 Hertz.

Explanation:

Frequency is a parameters which describe a wave. This is defined as the number of oscillations happening per unit second.

Mathematically,

$Frequency=\frac{1}{\text{Number of oscillations}}$

In the question,

Number of oscillations happening per second = 50

Putting this value in above equation, we get:

$Frequency=(1)/(50)\n\n\nu=0.02Hz$

Hence, the frequency of the wave is 0.02 Hertz.

You just told us how many times per second the wave oscillates. That's a definition of frequency. So the frequency of this wave is 50 per second or 50 hertz.

A merry-go-round makes 18 rotations in 3 minutes. What is its angular speed in rpm?

Answers

The angular speed in rpm will be 6. Angular speed is defined as the ratio of the revolution in the given time interval.

What is angular speed ?

The rate of change of angulardisplacement is defined as angular speed.

ω = n/t

Where,

n is the number of revolution

t is the time

ω is the angular speed

ω = n/t

ω = 18/6

ω = 3 rpm

Hence,the angular speed in rpm will be 6 .
