Answer:
Price elasticity of demand = 0.25
Explanation:
The detailed steps and appropriate derivation is as shown in the attached file.
The correct answer is
(1) speed
In fact, the speed of an electromagnetic wave does not depend on the type of wave, but only on the medium: since both the waves are travelling in vacuum (same medium), they are travelling at same speed, which corresponds to the speed of light in vacuum:

As we know that fundamental frequency is given as

here we know that

here we have
m = mass of wire = 5 g
l = length of wire = 90 cm


from above formula now



now we know that tension is due to weight of the sculpture so we will have


so its mass will be 11.76 kg
Answer:
a) horizontal range s=277671.77 m
b) time the shell is in motion 301.143 s
Explanation:
Is a parabolic movement so the velocity have two components:

°
