7. A car travels a certain distance with a speed of
goblinko [34]
Let distance be x.

Time in going, t 1 = x/50

Time in coming, t 2 = x/40

Total time T = x/40 +x/50 = 9x/200

Average speed = total distance/ total time

=( x+x)/(9x/200)= 2x ×200/9x = 400/9 = 44.44 km/h

A man pushes a shopping cart at a constant speed. What happens if the man increases the force on the cart?
Bezzdna [24]

Answer:

The cart would speed up.

Explanation:

According to Newton's 1st law, object subjected to no force, or net force 0, would have a constant speed. In our case the cart is initially at constant speed, meaning the man exerts a force that is equal to friction force. If he increases the force on the cart, the net force would no longer be 0. The cart would gain an acceleration and increases its speed.

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.
