while taking a turn on a track, the track provides the frictional force acting towards the center of the curve. we know that to move in a curve, centripetal force is required. here since the frictional force acts towards the center, it provides the necessary centripetal force to move in circle. hence the correct choice is

friction

Answer: acceleration is 2m/s^2

initial velocity is 4m/s

Explanation:

Since slope is rise/ run in this graph it will be change in velocity/ change and time. Therefore the slope of the graph will tell you the acceleration is 2m/s^2. The y intercepts is the velocity then time is 0, therefore the initial velocity is 4 m/s

can the suns gravitational pull on the earth affect the temperature as the gravitational pull could suck us in like a black hole

Harlamova29_29 [7]

A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.

Suppose the demand for air travel decreases (as illustrated in the graph below). A decrease in demand _____ the equilibrium pric

vfiekz [6]

Answer:

decreases, decreases

Explanation:

A decrease in the demand will create a fall in equilibrium prices and the quantity supplied will also decrease. As the equilibrium prices in the market are the price in which the quantity demanded equals to quantity supplied.

If the demand for the air decreases then the quantity of the air travel will also decrease and thus when the supply and demand change so do the changes associated with the equilibrium prices.
