Answer:
Initial Velocity= 49 m/s
Time period= 5 secs
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending
The initial velocity can be calculated using the expression below
u= √( 2gh)
Where g= Acceleration due to gravity= 98 m/s^2
h= height
Substitute the values we have
u = √(2*9.8*123)
u=√( 2410.8)
u = 49 m/s
the time period can be calculated as
(49/9.8)
= 5 sec
Hence time period is 5 secs

Answer:
B. Both I and II are true.
Explanation:
<em> The average total cost of a given level of output is the slope of the line from the origin to the total cost curve at that level of output</em>
The average total cost is defined as the sum of all total costs divided by the quantity produced. In other words, the cost of one unit of production. The average cost curve as shown in the diagram is U-shaped, where it falls with economies of scale and later rises as diseconomies of scale sets in.

<em>The marginal cost of a given level of output is the slope of the line that is tangent to the total cost curve at that level of output</em>
Marginal cost is the change that occurs in the total cost when quantity produced increases by one unit. In other words, it is the cost of producing an additional unit of a good. As per the diagram, the slope of the line tangent to the TC (TC = AC x Q1) curve at Q1 is the firm's marginal cost at this output level.
<span>One criticism against the ‘supply-slide’ cuts in the marginal
tax rates is that they fail to increase the aggregate supply in a more rapid
way, in which are the goods and services in total that are available in the
market and that they fail to increase it more than of the aggregate demand
which is the goods and services’ final demand.</span>
