Explanation:
20 men can do 1 W in 36 days
=> 20 men can do 1/36 W in 1 day
=> 10 men can do 1/72 W in 1 day.
30 girls can do 1W in 36 days
=> 30 girls can do 1/36 W in 1 day
=> 12 girls can do 1/90 W in 1 day.
Together 10 men and 12 girls can do 1/72 + 1/90 W in 1 day
= 9/360 = 1/40 W in 1 day.
Therefore they need 40 days to do the piece of work.
Aspects of a study conducted of cars in a certain country will be to determine the general traits of consumer buying and motorists. This could include: whether a car runs on diesel or electricity to gain information for a survey on pollution of motor vehicles; also, size of a car, the frequency of use, the purpose of use, how old a car is and how many passengers are generally seated in the car. All of these factors can be used to glean invaluable information for the automotive industry, as well as for scientific studies and governments.

Explanation:
Answer:
India, Pakistan, and China are unlikely to risk a significant conflict over their competing claims in Kashmir because the three nations are nuclear powers, with which an eventual military conflict in the region could imply a nuclear escalation that would significantly affect global stability. .
Indeed, China is one of the five countries authorized to possess nuclear weapons by the Nuclear Non-Proliferation Treaty. For their part, both India and Pakistan are not party to the treaty, and have developed their own nuclear weapons.
Thus, China has about 200 active nuclear warheads, Pakistan about 90 and India about 70, that is, the three nations have the possibility of destroying each other if they wish so. And it is precisely this possibility that limits the escalation of conflicts in the region: the fear of being destroyed by the enemy makes the peace to last.
The correct answer is social loafing.
Social loafing refers to the phenomenon where a person puts in less effort to achieve a goal, when he/she is part of a group, compared to when he/she is working alone. Social loafing usually occurs due to diffusion of responsibility, where a person feels less responsible and motivated to help out, when he/she is in a group with other people. In this instance, Carlene demonstrates that she dislikes social loafing because she believes that when working in a group, there is always going to be someone who is content to sit back and let others do the work.
