Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Answer:
A) Jose B) Roberto
Explanation:
Absolute advantage is the advantage when work is given two individuals or producer and provide the same resources, the person who works faster and better can have the absolute advantage.
For example, if my friend is washing 100 dishes in one hour and on the other hand I am washing some dishes in two hours or we can say I am washing 50 dishes in one hour then my friend has more absolute advantage in dish washing skills than me.

The principle of market segmentation assumes that Consumers are both similar to and different from each other enough to identify potential groups of buyers.
Option: A
Explanation:
Before introducing or launching a product into a market it is very necessary to have overall knowledge about the nature and types of customer so that producer and seller can have a basic sense of customer's inclination.
For this market segmentation is very important. It is a process refers to the division of market on the basis of public's food habit, choice of product, tradition, nature and behavior. Each and every consumer is similar to and different from each other enough to identify potential groups. Identification of potential groups benefited both the producer and seller.
