Answer: The answer will be R1 = B
Explanation:
Cause Here x component of A = A
X component of 2B = 2BcosФ
X component of Resultant = 0
I.e. A + 2BcosФ = 0
cosФ = -A/2B
also R1 = √(A² + B² + 2ABcosФ)
=√ [A² + B² + 2AB(-A/2B)]
=√A² + B² -A²
R1 = √B²
R1 = B so R1 = B is correct.
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.
Answer:
An organelle is a structure in a cell that has specific jobs to do. Organelles are held in the cytoplasm
Answer:
Option C : 290 J
Explanation:
We can use conservation of energy to estimate the kinetic energy when the object hits the ground:
When the object is at its initial height of 15 meters, it velocity is zero (falls from this position), therefore the total energy it possesses is due to potential energy given by the expression:
Joules
At the moment the object hits the ground from its free fall, its potential energy is zero, while its kinetic energy must equal the rest. So at that moment the object's kinetic energy must be 294 Joules.
