The answer is "positive" because a vector can be represented by an arrow. An arrow or "vector" can be denoted by drawing the size of the arrow in proportion to the magnitude of the vector. The positive and negative are designated for direction...
Good luck -Abi :)
The answer is D, by adding the most water you will get the most diluted solution.
Answer:
30,000N/m²
Explanation:
Given parameters:
Pressure on two legs = 15000N/m²
Total surface area of contact = 0.02m²
Surface area on one leg =
= 0.01m²
Unknown:
Pressure exerted if she stood on one leg = ?
Solution:
Pressure is the force per unit area on a body.
Pressure =
The force she is exerting is due to the weight her both. Standing on both feet and on a single feet is based on the same source of force;
Force = pressure x area
Force = 15000 x 0.02 = 300N
So;
Pressure from one leg =
= 30,000N/m²
Neither the speed nor the distance of a falling object is linearly related to time.
