When a porter moves with a suitcase on his head on a horizontal level road the work done by the lifting force or force of gravity is?

When a porter moves with a suitcase on his head on a horizontal level road the work done by the lifting force or force of gravity is?

A porter carrying a load on his head on a horizontal road does no work against Gravity.

How much work is done by a porter while carrying load on his head explain?

Because person moves horizontal and force of gravity is vertical. So work done is Zero.

What is the work done by the Porter against the force of gravity when he is carrying a load on his head and walking on a horizontal platform?

work done is zero because the force acting on load is in downward direction (weight due to gravity) and displacement is in horizontal direction.

Which of the following competitive forces comes from horizontal competition?

The Five Forces include – three forces from ‘horizontal’ competition: the threat of substitute products or services, the threat of established rivals, and the threat of new entrants; and two forces from ‘vertical’ competition: the bargaining power of suppliers and the bargaining power of customers.

What force does Porter carry luggage?

Explanation: Gravitational force on the box is acting in the downward direction.

When a porter moves with a suitcase on his head?

So the porter with the suitcase on his head will cover both the vertical and the horizontal distances. So along with moving forwards, he will also move vertically downwards. Since the suitcase is carried by the porter, the suitcase will also cover distances in the horizontal and the vertically upward directions.

What is the work done by a porter carrying 20kg along the horizontal direction to a point 10m away from the initial position?

The work done by the porter is 392 J =390 J.

When a porter carries luggage on his head work done by him is 1 point a positive B negative C Zero D Non Zero?

=> Work done by gravity force is positive. When Porter stands on the platform with suitcase in his head,then there is no moment in suitcases. So, work done by Porter on suitcase is 0.

What is the work done by gravitational force in case of person walking on horizontal road?

In this case gravitational force is acting in vertically downward direction and displacement is in horizontal direction. Hence, work done by the person is zero.

What is the total moment of weights of all the particles about the Centre of gravity?

zero
The centre of gravity (C.G.) of a body is the point about which the algebraic sum of moments of weights of all the particles constituting the body is zero.

What are the 5 competitive strategies according to Porter?

Porter’s Five Forces is a framework for analyzing a company’s competitive environment. The number and power of a company’s competitive rivals, potential new market entrants, suppliers, customers, and substitute products influence a company’s profitability.

Is Porter’s 5 forces internal or external?

As the name suggests, there are five factors that make up Porter’s 5 Forces. They are all external, so they have little to do with the internal structure of a corporation: Industry competition: A higher degree of competition means the power of competing companies decreases.
