The speed during the first hour is the slope of the piece of line that shows the first hour on the graph.
Average speed is always=(distance covered)/(time to cover the distance)
Distance covered during the first hour = from 0 miles to 40 miles on the graph; that's 40 miles.
Time to cover the distance = from 0 hours to 1 hour on the graph; that's 1 hour
Average speed = (40 miles) / (1 hour)
Average speed during the first hour = 40 miles/hour
I love you too.
Answer
Structural psychology was first described by Tichener. He was student of wilhelm Wundt. Wilhelm wundt was the first person who has established psycholoogical laboratory. In this laboratory structuralist approach of psychology was used. Structuralism is supposed to be first formal theory in psychology. Structuralism separated psychology from biology and philosophy into its own discipline.structuralist method suggested that psychology is purely theoretical.
William James was a scientist who has established a laboratory in which Functionalism approach is used. Functionalism was not accepted in America. Functionalism was a reaction to structuralism. William James was not satisfied with structuralism and then he proposed Functionalist method. William James suggested that psychology should be practical instead of theoretical as was proposed in the structuralist method. He also suggested that the existence of consciousness and mind has a particular purpose, which should be the focus of the study.
Answer:
angle is 19.85°
Explanation:
given data
grade = 36.1 %
vertically distance y = 36.1 m
horizontal distance x = 100 m
to find out
angle
solution
we know that according to question here
it make a triangle shape that contain 100 m base and height 36.1 m
and make angle with base is θ
so by triangle we know here
tanθ = y/x ..........1
so we now put x and y and find θ
tanθ = 36.1 / 100
tanθ = 0.361
θ = 19.85°
so angle is 19.85°
Reflection occurs in many scenarios in our everyday life. Reflection occurs
when light travels in one medium and comes into contact with another.
However, what if a light wave is moving from one location to another but
the mediums stay the same, what happens to that light wave?*
it will reflect with the same amount of intensity
Answer:
80N/cm^2
Explanation:
Given data
A car of weight 6,400N
Area= 80cm^2
The weight is distributed evenly on the 4 wheels
hence 6400/4
=1600
N
We know that
Pressure = force/Area
Pressure= 1600/80
Pressure= 20 N/cm^2
For the four wheels, the pressure is
=20*4
=80N/cm^2
