STP-তে একটি আদর্শ গ্যাসকে প্রথমে তার প্রাথমিক আয়তনের এক-তৃতীয়াংশে সংকুচিত করা হয়, এবং তারপর প্রসারিত হতে দেওয়া হয় যতক্ষণ না তার চাপ প্রাথমিক চাপের অর্ধেক হয়। উভয় প্রক্রিয়ায় গ্যাসের তাপমাত্রা স্থির থাকে। যদি গ্যাসের প্রাথমিক অভ্যন্তরীণ শক্তি । হয়ে থাকে তাহলে এর চূড়ান্ত অভ্যন্তরীণ শক্তি কত?

Answer the question on the basis of the given information. Businesses are suffering because of lack of money available for development loans.To help businesses,the government plans to modify the income- tax structure in order to induce individual tax payers to put a larger portion of their incomes into retirement savings accounts, because as more money is deposited in such accounts, more money becomes available to borrowers. Which of the following, if true, raises the most serious doubt regarding the effectiveness of the government's plan to increase the amount of money available for development loans for businesses?
ক When levels of personal retirement saving increase, consumer borrowing always increases correspondingly.
খ The increased tax revenue the government would receive as a result of business expansion would not offset the loss in revenue from personal income taxes during the first year of the plan.
গ Even With tax incentives,some people will choose not to increase their levels of retirement savings .
ঘ Bankers generally will not continue to lend money to Businesses whose prospective earnings are insufficient to meet their loan repayment schedules.
