Psychologists study animals because they want to understand how different species think and behave, animal psychology is often simpler and easier to understand than human physiology, and it is more permissible to conduct certain types of research with animals than with humans

Explanation:

Psychology is the science that studies the mind. The aim of a psychologist is to understand the behavior and motivations of an animal including humans. There are various reasons why psychologists study animals they are:

An animal has the same basic drives that a human does but animal has different variables that controls their behavior in order to fulfill their drives.

An animal may have a shorter lifespan, different food habits, different sleep habits etc. How does the animal behave considering all these variables in mind is the function of the psychologist to figure out.

Understanding the mind of an animal helps us to know more about the animal. We may be use this information for our benefit like training a dog, horse etc.

With what we can learn from animals can also give us an insight into the minds of humans as well.

Also it is easier to control the variables in an experiment of an animal rather than a human and there are less ethical reasons to be considered.

Kitty [74]

Answer:

68cm

Explanation:

You can solve this problem by using the momentum conservation and energy conservation. By using the conservation of the momentum you get

p_f=p_i\\mv_1+Mv_2=(m+M)v

m: mass of the bullet

M: mass of the pendulum

v1: velocity of the bullet = 410m/s

v2: velocity of the pendulum =0m/s

v: velocity of both bullet ad pendulum joint

By replacing you can find v:

(0.038kg)(410m/s)+0=(0.038kg+4.2kg)v\\\\v=3.67\frac{m}{s}

this value of v is used as the velocity of the total kinetic energy of the block of pendulum and bullet. This energy equals the potential energy for the maximum height reached by the block:

E_{fp}=E_{ki}\\\\(m+M)gh=\frac{1}{2}mv^2

g: 9.8/s^2

h: height

By doing h the subject of the equation and replacing you obtain:

(0.038kg+4.2kg)(9.8m/s^2)h=\frac{1}{2}(0.038kg+4.2kg)(3.67m/s)^2\\\\h=0.68m

hence, the heigth is 68cm

Answer:

3.82746e+26 watts

Explanation:

There are two ways to solve this problem. One way is to use the equation

L = 4πσR²T⁴

where

L = the sun's bolometric (all-spectrum) luminous power

σ = 5.670374419e-8 W m⁻² K⁻⁴ = the Stefan-Boltzmann constant

R = 6.957e+8 meters = the sun's radius

T = 5771.8 K = the sun's effective temperature

You find that

L = 3.82746e+26 watts

The other way to solve the problem is to use the Planck integral for radiant flux.

L = 4π²R ∫(v₁,v₂) 2hv³/{c² exp[hv/(kT)]−1} dv

where

h = 6.62607015e-34 J sec

c = 299792458 m sec⁻¹

k = 1.380649e-23 J K⁻¹

v₁ = 0 = frequency band lower bound, in Hz

v₂ = ∞ = frequency band upper bound, in Hz

You find, once again, that

L = 3.82746e+26 watts

The advantage of using the Planck integral becomes clear when you want to calculate the sun's luminous power only in a specific band, rather than across the entire spectrum. For example, if we do the calculation again, except that we use

v₁ = 4.1e+14 = frequency band lower bound, in Hz

v₂ = 7.7e+14 Hz = frequency band upper bound, in Hz

restricting ourselves to the visible spectrum. We find that

L (visible) = 1.56799e+26 watts

So the fraction of the sun's luminosity that is in the visible spectrum is

L (visible) / L = 0.4096686

Aleks04 [339]

The statement ‘An advantage of electron microscopes compared to light microscopes is that electron microscopes are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes do not have higher resolution that allows you to view smaller specimens allow you to view the true colors of the specimens being viewed’ is true. In fact, electron microscope is more efficient than a light microscope due to its mechanism using only light without magnifying the specimen a thousand times.
