Answer:
A fall in the price of the price of jet fuel _______ the marginal cost of producing air trips.
D. Decreases
A fall in the price of jet fuel _________ the market price and _______ the equilibrium quantity in the short run.
D. decreases
C. increases
Explanation:
Marginal Cost = Total Change in Cost/Change in Quantity
Marginal Cost is the Cost of the additional unit produced . For example if we have 10 trips of the jet per day and the number of the passengers increase on less air ticket costs the marginal cost will decrease.
A fall in the price of jet fuel decrease the market price of the fuel. As the supply is increased the demand decreases .
The equilibrium quantity is increased as more fuel is available and costs are reduced.
C, due to stuff and whatnot
1. LSD (or long slow distance) training, also known as a continuous training, involves performing an activity, such as jogging, cycling or swimming, nonstop for a period of time. This training is targeted for health-related improvements and is often required before engaging to more demanding, aerobic methods like fartlek. Medium-range on the other hand, is where the work period is dominated by the lactic acid energy system. This occurs either when the work period is between 10 and 60 seconds or when the work-to-rest ratio is 1:2 or 1:3. The aim of medium-interval training is to develop tolerance of lactic acid.
2. The starter phase allows the body to get used to the idea of exercise, avoid soreness and injury, and to experiment until you find the program that works best for you.
Answer
given,
weight of the oak board = 600 N
Weight of Joe = 844 N
length of board = 4 m
Joe is standing at 1 m from left side
vertical wire is supporting at the end.
Assuming the system is in equilibrium
T₁ and T₂ be the tension at the ends of the wire
equating all the vertical force
T₁ + T₂ = 600 + 844
T₁ + T₂ = 1444...........(1)
taking moment about T₂
T₁ x 4 - 844 x 3 - 600 x 2 = 0
T₁ x 4 = 3732
T₁ = 933 N
from equation (1)
T₂ = 1444 - 933
T₂ = 511 N
