Mostly because you need to understand the chain of command.
In a centralized organization, the decision making process fall to the hands of a very few people (in some case, it even can fall to one person) , which mean all level of managers can't move freely without the decision maker approval.
In a Decentralized organization, all different managers from different divisions have the authority to make decision
Answer:
Resulting amplitude, A = 0 cm
Explanation:
The phenomenon of interference occurs when two travel and meet at the same point. There are two conditions for interference. The first one is constructive and the other one is destructive.
In this case, two waves have same amplitude but they are not in same phase such that they meet at point X and destructive interference occurs.
Let A is the amplitude of the resulting wave such that,
A = 0
So, the amplitude of the resulting wave is 0 cm. Hence, the correct option is (A).
Answer:
b.
Explanation:
Parallax is the effect whereby the position or the direction of an object appears to differ, when viewed from different positions. e.g. through the view finder and lens of the camera.
a valid way of demonstrating parallax for yourself is by b.Hold up your hand in front of your face, and alternately close your left and right eyes.
Answer:
The oscillation frequency of the spring is 1.66 Hz.
Explanation:
Let m is the mass of the object that is suspended vertically from a support. The potential energy stored in the spring is given by :
k is the spring constant
x is the distance to the lowest point form the initial position.
When the object reaches the highest point, the stored potential energy stored in the spring gets converted to the potential energy.
Equating these two energies,
.............(1)
The expression for the oscillation frequency is given by :
(from equation (1))
f = 1.66 Hz
So, the oscillation frequency of the spring is 1.66 Hz. Hence, this is the required solution.
Answer:
Solution
The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54].
