Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. But there are other factors that determine the quantity as vector or scalar quantity. If the physical quantity obeys the laws of vector addition such as triangle law of vector addition and parallelogram law of vector addition, then the quantity is said to be a vector quantity.
In the case of electric current, when two currents meet at a junction, the resultant current of these will be an algebraic sum and not the vector sum. Therefore, an electric current is a scalar quantity although it possesses magnitude and direction.

The number series 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, . . . . , 240.
The first term a = 8
The common difference d = 8
Total number of terms n = 30
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 30/2 x (8 + 240)
= (30 x 248)/ 2
= 7440/2
8 + 16 + 24 + 32 + 40 + 48 + 56 + 64 + 72 + 80 + 88 + 96 + . . . . + 240 = 3720
Therefore, 3720 is the sum of first 30 positive integers which are divisible by 8

Regeneration is the ability of an organism to grow into a complete individual when its body is divided into any number of pieces. It can be seen in Hydra and Planaria.
Regeneration is carried out by specialized cells which proliferate and further make large number of cells. From this mass of cells, different cells undergo changes to become various cell types and tissues. These changes take place in an organized sequence referred to as development.

An exothermic reaction is a reaction in which energy is liberated out.
Respiration is considered as exothermic reaction because energy is released in this process.
Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.
C₆H₁₂O₆ + 6O₂ ----> 6CO₂ + 6H₂O + energy

Advantages of term loans
- The loan is not repayable on demand and so available for the term of the loan - generally three to ten years - unless you breach the loan conditions.
- Loans can be tied to the lifetime of the equipment or other assets you're borrowing the money to pay for.
- At the beginning of the term of the loan you may be able to negotiate a repayment holiday, meaning that you only pay interest for a certain amount of time while repayments on the capital are frozen.
- While you must pay interest on your loan, you do not have to give the lender a percentage of your profits or a share in your company.
- Interest rates may be fixed for the term so you will know the level of repayments throughout the life of the loan.
- There may be an arrangement fee that is paid at the start of the loan but not throughout its life. If it is an on-demand loan, an annual renewal fee may be payable.
Disadvantages of loans
- Larger loans will have certain terms and conditions or covenants that you must adhere to, such as the provision of quarterly management information.
- Loans are not very flexible - you could be paying interest on funds you're not using.
- You could have trouble making monthly repayments if your customers don't pay you promptly, causing cashflow problems.
- In some cases, loans are secured against the assets of the business or your personal possessions, eg your home. The interest rates for secured loans may be lower than for unsecured ones, but your assets or home could be at risk if you cannot make the repayments.
- There may be a charge if you want to repay the loan before the end of the loan term, particularly if the interest rate on the loan is fixed.

- Every loan agreement specifies an interest rate which the borrower must pay to the lender along with repayment of the principal.
- In addition, lender may demand collateral, i.e., an asset that the borrower owns and uses this as a guarantee until the loan is repaid.
- If the borrower fails to repay the loan, the lender has the right to sell the collateral to obtain payment.
- Terms of credit comprise interest rate, collateral and documentation requirement, and the mode of repayment.
*The terms of credit vary substantially from one credit arrangement to another. They may vary depending on the nature of the lender and the borrower.
