Answer:
0.882 m/s average velocity and 1.71 m/s average speed
Explanation:
The dog travels a total of 35 m west and 110 m east.
110-35 = 75 m east of the starting position. Since velocity is a vector you must consider its first and final position and not the total distance traveled.
75 m / 85 s = 0.882 m/s average velocity
Speed is not concerned with direction so we instead add the total distance traveled which is 35+110 = 145 m. We then perform the same operation as before and divide by the time it took to run this distance.
145 m / 85 s = 1.71 m/s average speed
Free fall means rapid fall or a downward motion due to gravity. Sentence example: When Joe was accidentally bumped by Sarah, he was sent towards a free fall down the escalator, leading to a serious injury on his arm and two legs.
Variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.
<h3>What is aggregate-supply?</h3>
The entire quantity of goods and services that enterprises in a national economy intend to sell during a certain time period is known as aggregate supply
Variables shift both the long-run and short-run aggregate-supply curves are ;
1. Productivity
2. Labor Wage Costs.
3. Taxes and other costs -
4. Material Prices.
5. Size of labor force.
6. Stock of Capital.
Hence, variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.

Answer:
126.33 N/m
Explanation:
Angular frquency is given by
Wheret is period of wave and f is angular frequency.
Given period of 0.5 s then
Angular frequency is also given by
Making k the subject then 
Where k is spring constant, m is mass
Substituting m with 0.8 then
K=126.330936333944 N/m
Rounded off as 126.33 N/m
