Answer:
x-component=-9.3 m
Magnitude of A=17.7m
Explanation:
We are given that
We have to find the x-component of A and magnitude of A.
According to question
Substitute the values then we get
m
The value of x-component of A is negative because the vector A lie in second quadrant.
Hence, the x- component of A=-9.3 m
Answer:
As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.
The first organisms to live within a newly created patch of land are the Pioneer Species.
Answer:
A. I and V
Explanation:
According to Le Chatelier's Principle, increasing the product side will cause the equilibrium to shift back towards the reactant side, so I is true. By the same principle, II is false.
For gases, decreasing the pressure will cause the equilibrium to shift towards the side with higher number of moles. So V is true.
The reaction is endothermic, so increasing the temperature will shift the equilibrium to the products, so IV is false. And adding a catalyst has no effect on the equilibrium, so III is false.
