Define habitat preservation and give at least two examples.

lisov135 [29]

Habitat preservation is when people get together or just one person helps to stop the end of a living space for animals such as the monterey aquarium the help sea life by doing research to see why animals are dying and do what they can to stop it. another one if nation parks or forests you are not allowed to harm them in any way they are protected by laws(the government)

What is the average speed of an object that travels 50 meters in 2 seconds? Select one: a. 100 m/s b. 25 m/s c. 50 m/s d. 2 m/s

AURORKA [14]

Answer:

Average speed, v = 25 m/s

Explanation:

It is given that,

Distance travelled by the object, d = 50 meters

Time taken, t = 2 seconds

Average speed is defined as the total distance divided by total time taken i.e.

$v=\dfrac{d}{t}$

$v=\dfrac{50\ m}{2\ s}$

v = 25 m/s

So, the sped of the object is 25 m/s. Hence, this is the required solution.

What steps are involved in converting potential energy to kinetic energy

melomori [17]

Answer:

Decreasing in altitude and increasing in velocity

Explanation:

The formula for potential energy is:

$E_p = mgh$

where m is mass, g is constant gravitational energy and h is the potential altitude.

The formula for kinetic energy is:

$E_k = mv^2/2$

where v is the velocity

Since m,g are constant, to convert from potential energy to kinetic energy, h must decreases while v increases. For example dropping an object from a height.

A 51 kg woman skis down a hill and her kinetic energy is 9.96e4 j. What is her speed?

arlik [135]

Kinetic energy of woman is given as

$KE = 9.96 \times 10^4 J$

mass of woman is given as

$m = 51 kg$

now we will have

$KE = \frac{1}{2}mv^2$

$9.96 \times 10^4 J = \frac{1}{2}(51) v^2$

$v^2 = \frac{9.96 \times 10^4}{25.5}$

$v^2 = 3.91 \times 10^3$

$v = 62.5 m/s$

Calculate the diffraction limit of the human eye, assuming a wide-open pupil so that your eye acts like a lens with diameter 0.8

guapka [62]

Hi, thank you for posting your question here at Brainly.

This problem could be solved using this equation:

Diffraction limit = 1.22*wavelength/diameter

diameter = 0.8 cm = 0.008 m
wavelength = 500E-9 m

Diffraction limit = 1.22(500E-9)/0.008
Diffraction limit = 0.00007625
