By the law of reflection which says that the angle of reflection is equal to the angle of incidence, which in other words says, sin x = sin y, it can be said, based on the given that the angle of reflection is also equal to the angle of incidence of 35 degrees

klio [65]

Answer:

3.58\:\mathrm{s}

Explanation:

We can use the kinematics equation \Delta y=v_it+\frac{1}{2}at^2 to solve this problem. To find the initial vertical velocity, find the vertical component of the object's initial velocity using basic trigonometry for right triangles:

\sin28^{\circ}=\frac{y}{22},\\y=22\sin28^{\circ}=10.3283743813\:\mathrm{m/s}

Now we can substitute values in our kinematics equation:

  • \Delta y=-100
  • a=-9.8\:\mathrm{m/s^2} (acceleration due to gravity)
  • v_i=-10.3283743813\:\mathrm{m/s}
  • Solving for t

-100=-10.3283743813t+\frac{1}{2}\cdot -9.8\cdot t^2,\\\\-4.9t^2-10.3283743813t+100=0,\\\\\boxed{t=3.5849312673637455}, t=-5.692762773751501\:\text{(Extraneous)}

Why are the parts of an atom that electrons occupy called electron clouds?
Anna [14]

Because it's literally impossible to tell exactly where something that size is
located at any particular time.

And that's NOT because it's so small that we can't see it.  It's because any
material object behaves as if it's made of waves, and the smaller the object is,
the more the size of its waves get to be like the same size as the object. 
When you get down to things the size of subatomic particles, it doesn't make
sense any more to try and talk about where the particle actually "is", and we only
talk about the waves that define it, and how the waves all combine to become a
cloud of <em><u>probability</u></em> of where the particle is.

I know it sounds weird.  But that's the way it is.  Sorry.

What social science, which deals with the behavior and thinking of organisms, differs from sociology primarily in that it focuse
Svetlanka [38]

Answer : The correct answer is- Psychology.

As per the American Psychological Association, psychology can be described as the scientific study of mind and behavior of a particular individual.


There are primarily four goals of psychology that are to describe, to explain, to predict, and to control the  mental processes as well behavior of a person.

On the contrary, sociology focuses on behaviour of group of individuals. It is the study of structure, function as well as development of society.


Thus, psychology is the right answer to the question.

What do you mean by average velocity​
mina [271]

Answer:

Here is the answer. Hope this helps you!

Explanation:

Average velocity is the sum of initial and final velocity divided by 2. I t is the same as total Displacement divided by total time. Average velocity is calculated when the body is in non-uniform motion (also when total displacement and time is not given). The formula is as follows:

u + v/2 = v_{av}

Average velocity = Average speed

during motion in a straight line. therefore, the above mentioned formula can be used for calculating average speed as well, when the direction is one and only the same, that is, during motion in a straight line. The S.I unit remains the same-

m/s.

Since velocity is vector, average VELOCITY is also vector. However, Average SPEED is scalar as speed is scalar. both can be equal only when the distance = displacement and when they are following the same direction of motion.
