Seven of my best Brainly answers! Part 1

This post is about the answers I wrote on Brainly.

Using Brainly

Hi people! I have been using an app known as brainly since a few months and have pretty much climbed to the ACE rank a few days ago. It is a Q&A site that has helped me a lot and I am now really enjoying by contributing to it. Later I found that it was a well designed website.

Brainly has features of getting answers as the best and getting them certified. The one with both these marks are definitely in the section of finest articles on the site. I have over 50 best Brainly answers selected and I guess around 30 or 40 are certified by the team.

There are also many dedicated moderators. If you see their score, you get stunned! And yes, that is true. I with 3000 points, that’s like a child’s play. (even though it’s not). I have seen users with over 100,000 points and 1000s of incredible answers. They, are the real champions.

Q. In an household an electric bulb of 100 W is used for 10 hours and an electric heater of 1000W is used for 2 hours . calculate 1- ) the cost of using bulbs and the heater for 30 days .take the cost of one unit of electrical energy as 5 rupees.?
This physics question was quite interesting to do!
Ans. Given that,100 W =  bulb is used for 10 hours.
This means for one hour = 100/10 = 10 W per hour       …..(i)Now, heater of  1000 W is used for 2 hours.
This means for one hour = 1000/2 = 500 W per hour         ….(ii)Together they cost: (i) + (ii) = 10 + 500 = 510 W per hourIn 30 days, we have 510 x 30 = 15300 W.

Now, 1000 W = 1 KW

So, 15300 W = 15.3 KWH or 15.3 units

Now, 1 unit = 5 Rs.

Therefore, the cost for 15.3 units = 5 x 15.3 =

Hence, the final answer is Rs. 76.5

Q. A car moves with the speed of 30 km/h for half an hour , 25 km /h for one hour and 40 km/h for two hours . Calculate its average speed .

Ans. Let us find the distances first.

□ Car moves with 30 kmph for half an hour. This means 30 x 1/2 = 15 km

□ Car moves with 25 kmph for an hour. This means 25 x 1= 25 km

□ Car moves with 40 kmph for half an hour. This means 40 x 2 = 80 km

So, the total distance is 80 + 25 + 15 = 120

On, adding the hours, we have: 0.5 + 1 + 2 = 3.5 hours

□ Now we know that, S = D / T

Therefore, S = 120 / 3.5

Ans. 34.2 kmh is the average speed of the car.
