If we decide that the downward direction is positive (that is displacement, velocity etc.is +ve in the downward direction) then the direction opposite to it is negative.

If we drop a ball from roof then

• when the ball falls down it has +ve velocity

∴ the product m.v that is momentum is positive (mass cannot be negative) 

•  after the bounce, the velocity is in the negative direction

∴ product m.v that is momentum is negative

Ans. FIT stands for Fundamental of Information Technology.

No. It is not practical based completely.

Same thing in all subjects u have to do.

Ok bye

He'll

First of follow read the question properly and then search the answer of that question an example that ur question is based upon drought in ssc so see that where is the word drought and then write the answer. And write at least one page for each subject of OTBA so that 5 marks or 4 marks can easily get because teachers are seeing the quantity of answer if answer is of one page then full marks in OTBA.

Thanks

make shorcuts of each and everything you learned and before exam you just refer that shorcuts you will recoollect allthe knowledge from that shortcuts and do this the exam day (early morning)

Ans. Escape Velocity is the minimum speed needed for an object to "break free" from the gravitational attraction of a massive body.

Hello! MY dear friend Sadhna you should study 6 hrs each day from today and give about 1 hr to each subjects .

I hope that it may be useful for you

Thankyou for asking this question as this is one of the main problems faced by students during examinations. As the time progresses towards exams, we get caught by the fear as how we will solve the question paper in prescribed time limit.

For this, firstly solve sample papers and stick to the word limit. You will only get marks for writing the right answer not a long answer. Do not repeat the points in your answer or write the extra stuff which is not even asked. It won't fetch you any extra marks but would definitely waste your time. Practice sample papers and after that look up the solutions and compare that have you written the desired pointsonly. Eliminate the unwanted part.

By this, you will feel confident and will be able to score well in your examinations. All the best!

1. Start your editorial with a thesis-like statement.
2. Lead with an objective explanation of the issue.
3. Present the opposing argument first.
4. Present your reasons/evidence that directly refute the opposition.
5. Make your solution known.

7. Proofread your work.

Let side of a cube be a, then surface area of cube = 6a²

Now, new side of cube = a + 50% of a = 1.5a

New Surface area = 6 x (1.5a)² = 13.5a²

Increase in Surface area = 13.5a² - 6a² = 7.5a²

Percentage Increase in Surface area = 7.5a²/6a² x 100 = 125%

The reason behind the mild temperature on the the mountains of Syria and Lebanon in summer is that :

They both experience Mediterranean type of climate.. Their geography and relief feature is such that they experience the same temperature and simlar climate. The coast and the Western mountains experience Mediterranean  climate.
