Answer: The correct answer is-
C) The cost to develop the technology would be greater than what could be made in profits.
As per the information in the question, company believes that electric cars are the future of the automotive industry.
It indicates that in future, automobile industries will flourish and get maximum profit through selling of electric cars. This idea will only be fulfilled if the cost to develop the technology would be less and the profit made out of it is significantly larger.
Thus, out of the given factors, only option C) The cost to develop the technology would be greater than what could be made in profits will prohibit the company from developing the idea.
To solve this problem it is necessary to apply the concepts related to frequency and vibration of strings. Mathematically the frequency can be expressed as
Then the relation between two different frequencies with same wavelength would be
The beat frequency heard when the two strings are sounded simultaneously is
We have the velocity of the transverse waves in stretched string as
And,
Therefore the relation between the two is,
Finally substituting this value at the frequency beat equation we have
Therefore the beats per second are 11.92Hz
The watch hand covers an angular displacement of 2π radians in 60 seconds.
ω = 2π/60
ω = 0.1 rad/s
v = ωr
v = 0.1 x 0.08
v = 8 x 10⁻³ m/s
