Answer:

4times

Explanation:

The right-hand side of the equation \frac{v^{2} }{b} computes braking distance by applying a braking coefficient factor (b) to the square of the car's velocity.

the brake coefficient is 170 and the velocity of the car is V.

At 20mph = 20^2 divides 170 = 2.3594

At 40mph = 40^2 divides 170 = 9.4117

Hence it is 4 times greater of 20mph

2. In your own understanding, what is community in relation to political science?​
trapecia [35]

Answer:

A community is usually a combination of territorially defined people, united by, for example, history, kinship, co-operation, common values and way of life. Usually, a community is made up of people living close together, but a community can also be a larger number of people who have something in common, such as nationality, ideology or interests.

In turn, political science studies the impact that politics as a decision-making system has on the life of communities. Thus, it studies how governments affect the lives of their citizens through their policies, and how citizens react to them.

Therefore, the community is ultimately the subject on which the activity of the political sciences falls, as they study their relationship with politics.
