The power developed by the second crane is half that of the first crane.
<h3>
Power</h3>
Power is the ratio of the amount of energy to the total time. It is given by:
Power = Energy / time
Energy = mass * g * h
Let g represent the acceleration due to gravity and h the vertical height, for the first crane:
Power = 1200gh/20
For the second crane:
Power = 1200gh/40
Ratio of power in second crane to that of first = (1200gh/40) / (1200gh/20) = 0.5
The power developed by the second crane is half that of the first crane.

Answer:
the number of game tickets that could be bought
Explanation:
Let x represent the number of drinks. Since each drink costs $2.50, therefore the total cost for drinks = 2.5x.
Each game ticket cost $17. Let y represent the number of tickets bought, therefore the total cost for tickets = 17y.
Given that the total budget = $100, hence:
total cost for drinks + total cost for tickets ≤ 100
17y + 2.50x ≤ 100 (1)
Given the equation:
5(17) + 2.50x ≤ 100 (2)
comparing equation 1 and 2, we get that y = 5. Hence 5 represents the number of tickets bought
Answer:
Perception
Explanation:
Perception is the way you think about or understand someone or something. It is also what you understand or interpret from your five senses – touch, sight, sound, smell, and taste. However, perception is colored by our past experiences, feelings and thoughts.
