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.
Answer:
Explanation:
Thermal expansion is where materials expand while being heated, causing them to take up more space. Some materials expand more than others. But this all happens due to the motion of tiny little molecules. Temperature is the average kinetic energy of the molecules in a substance.
Thermal expansion is an important consideration for engineering because different materials exhibit changes in size when exposed to heat. Thus, affecting length, width, surface area, volume, shape etc
Answer:
Explanation:
h = height of the cliff
Consider upward direction as positive and downward direction as negative
Consider the motion of rock thrown straight up :
Y = vertical displacement = - h
v₀ = initial velocity = 8.63 m/s
a = acceleration = - 9.8 m/s²
t = time taken to hit the ground = 3 s
Using the equation
Y = v₀ t + (0.5) a t²
- h = (8.63) (3) + (0.5) (- 9.8) (3)²
h = 18.21 m
Consider the motion of rock thrown down :
Y' = vertical displacement = - 18.21
v'₀ = initial velocity = - 8.63 m/s
a' = acceleration = - 9.8 m/s²
t' = time taken to hit the ground = ?
Using the equation
Y' = v'₀ t' + (0.5) a' t'²
- 18.21 = (- 8.63) t' + (0.5) (- 9.8) t'²
t' = 1.2 s
Answer:
The answer is a=b=c=3.833 cm
Explanation:
Lets call the variables a=side a b=side b c=side c
We have that the formula of the equilateral triangle for its height is:
1)h=(1/2)*root(3)*a
2) If we resolve the equation we have
2.1)2h=root(3)*a
2.2)(2h/root(3))=a
3) After the replacement of each value we have that
a=2*3.32/1.73205
a=3.833 cm
And we know that the equilateral triangle has the same value for each side so a=b=c=3.833 cm
