The weight of an object when calculated by multiplying with the pull of the gravity is dependent on the mass of the object and the value of g. The value of g is constant however is still dependent on the distance of the object from the center of the Earth. Thus, the answers are <em>mass and distance. </em>
Answer:

Explanation:
Given:
- average walking speed,

- average biking speed,

<u>According to given condition:</u>

where:
time taken to reach the building by walking
time taken to reach the building by biking
We know that,

so,



Answer:
final temperature will be 0 degree C
Total amount of ice will be

total amount of water

Explanation:
After thermal equilibrium is achieved we can say that
Heat given by water = heat absorbed by ice cubes
so we will have
Heat given by water to reach 0 degree C



heat absorbed by ice cubes to reach 0 degree



so we will have

so here we can say that few amount of water will freeze here to balance the heat



so final temperature will be 0 degree C
Total amount of ice will be


total amount of water


Using the constant acceleration formula v^2 = u^2 + 2as, we can figure out that it would take a distance of 193.21m to reach 27.8m/s
