Dr. Prasun Sharma Chowdhury 5 years, 7 months ago

According to Newton's Second Law: If a particle of mass {tex}m{/tex} has velocity {tex}v{/tex} at any moment {tex}t{/tex},

{tex}\vec{F}=\frac{d\vec{p}}{dt}{/tex}, where {tex}\vec{F}{/tex}is the force and {tex}\vec{p}=m\vec{v}{/tex} is the momentum.

Thus,

{tex}\vec{F} =\frac{d(m{\vec{v}})}{dt} =m\frac{d\vec{v}}{dt}+\vec{v}\frac{dm}{dt}{/tex}

For cases where mass changes with time, the above equation would be applicable.

Special Cases:

  • If mass remains constant, as we see in most theories an numericals, {tex}\frac{dm}{dt}=0{/tex} hence, {tex}\vec{F}=m\frac{d\vec{v}}{dt}=m\vec{a}{/tex}, where {tex}\vec{a}{/tex} is the acceleration of the object.
  • If the velocity remains constant but mass emerges out or gets added at a constant rate, as in cases of water coming out of hose pipe, or sands added at constant rate upon a moving belt; {tex}\vec{F}=\vec{v}\frac{dm}{dt}{/tex}.

Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. The earliest known life-forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya, relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.

Types of Warehouses : There are various types of warehouses :
1. Private Warehouses : These are the warehouses owned by the traders or producers. In these warehouses they keep their own products and do not allow anybody else to keep their goods. Hence they are called private warehouses.
2. Public Warehouses : These warehouses are owned by private companies and government agencies. These godowns are large size and used by all persons such as traders, farmers, exporters, importers and government agencies. These godowns are located in the commerical centres of big cities. Their main objective is to make earning by providing storing facilities.
Once the goods are stored in the godown, warehouse receipt is issued to the owner of goods. After making the payment of godown charges goods are returned.
3. Bonded Warehouses : These are public warehouses which are licensed by the Government to accept imported goods for storage before payment of customs duty by their importers. When the importer finds that he cannot conveniently make payment of customs duty on the goods imported by him, he can request the customs authorities for storage of goods in the bonded warehouse till the customs duty is paid.
4. Duty paid Warehouses : These warehouses are located near the ports but are outside the dock bonds. They are constructed by Port Trust Authorities. We have such warehouses in Mumbai. When duty is paid on imported goods the importer can take the goods away into the domestic market.

(1) Njicleotide : Each nucleotide consist of 3 units - a nitrogenous base, a pentose sugar and phosphate group.
(2) Nitrogenous base: Nitrogenous base are the purine (adenine or guanine) or pyrimidine (thymine, cytosine or uracil).
(3) The nucleotides are mono or di or triphosphates of nucleosides, e.g., Adenosine monophosphate (AMP), Adenosine diphosphate (ADP) and Adenosine triphosphate (ATP).

Very easy.
Sol: Car = C = 20% = 0.2
        Bus = B = 50% = 0.5
        {tex}\huge {C \cap B = \text {10 % } = 0.1}\\ \therefore \huge {C \cup B =0.2+0.5-0.1 = 0.6}\\ \huge {\text {Thus, Car or Bus = 60%.} }{/tex}

He is agent because he represent them and all the members binds by his act . And he can also be the principle because he bound by the act of other members in the partnership form of business organization. .

Mutual agency is the right of all partners to represent the company's normal business operations and the authority to bind it to mutual contracts and agreements. In leman's terms, it is the authority given to a person doing business on behalf of the company, usually a business owner or partner. Mutual agency is the legal relationship between partners in a partnership where each partner has authorization powers and the ability to enter the partnership into business contracts. In other words, each partner in the partnership is an agent in the business and the authority to make business decisions that commit or bind the partnership, as a whole, to a business agreement with a third party or entity.
Mutual agency only exists for partners acting within the scope of normal business operations and dealings. For example, a retailer apparel partner with agency would not be able to contract the other partners into a deal to purchase a piece of investment real estate because this would be outside the normal operations of the business.

One of the retail partners can, on the other hand, purchase goods from a vendor and require the partnership pay for the goods. This transaction is within the normal course of operations of the business.
