Answer:
1) v = 7.70 10³ m/s
, 2) F = 115 N and 3) (F/W)% = 90.2%
Explanation:
1) To solve the problem let's use Newton's second law where force is gravitational force and acceleration is centripetal
F = ma.
F = G m M / r²
a = v² / r
G m M / r² = m v² / r
G M / r = v²
Let's look for the distance is the distance from the surface of the has to the station 345 103 m plus the radius of the Earth
r = Re + 345 103
r = 6.37 10⁶ + 3.45 10⁵
r = 6.715 10⁶ m
Let's calculate the speed
v = √ (6.67 10⁻¹¹ 5.98 10²⁴ / 6,715 10⁶) = √ (59,399 10⁶)
v = 7.70 10³ m/s
The speed module is constant, so we can use the uniform motion relationships
v = d / t
The distance is the length of the circle
d = 2π r
d = 2π 6.715 106
d = 42.2 10⁶ m
Let's calculate the time
t = d / v
t = 42.2 10⁶ / 7.70 10³
t = 5.48 10³ s
2) Let's use the universal gravitation equation
F = G m M / r²
F = 6.67 10⁻¹¹ 13.0 5.98 10²⁴ /(6.715 10⁶)²
F = 11.5 10¹ N
F = 115 N
3) in this for we are asked the relationship is out with the weight of the body on earth
F / W = F / mg
F / W = 115 / (13.0 9.8)
F / W = 0.902
F / W% = 90.2%
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.
