ANEK [815]

Answer:

The net money the farmer will get

= Rs. 39,500

Explanation:

The farmer bought 5 kg seeds of rice at Rs. 100 per kg.

Cost price = 5 × 100 = Rs. 500

And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg

Selling price = 1000 × 40 = Rs. 40,000

The farmer's net profit

= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500

Solar, wind, and hydroelectric energy<br> are examples of<br> resources.
strojnjashka [21]

Answer:

Renewable Energy Resources.

Explanation:

Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.

Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.

Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
