Answer:
Any medium or material of high refractive density e.g Water which refracts the light rays 1&2 away from their normal
Hi there!
Acceleration:
a = Δv / Δt, so:
a = 20/9 ≈ 2.22 m/s²
Displacement:
We can use the equation Δd = v₀t + 1/2at² to solve. (Initial velocity is 0).
Δd = 1/2at²
Plug in the acceleration and time:
Δd = 1/2(2.22)(9)² ≈ 89.91 m
Frequency heard by listener: fl = ?
frequency of source: fs = 300 Hz
velocity of listener: vl = 16 m/s
velocity of source: vs = 0
<span>velocity of sound in air: c = 344 m/s
</span><span>fl = fs [(c – vl)/c] = 300[(344-16)/344]
</span> =286.04 Hz
Fossil fuels are formed by organic remains that have been buried under rock. "Organic remains" can include animals and plants (think of oil and dinosaurs).
Answer:
of motivations to give a socially desirable response
Explanation:
The bogus pipeline is nothing but a polygraph machine which is fake.
With the help of a polygraph test it can be determined whether a person is telling the truth. This is done by measuring physiological indicators of a human being such as blood pressure, respiration, pulse, and skin conductivity.
The bogus pipeline appears to be like a real polygraph machine. It is assumed that people will be truthful as they believe that the machine is real. Nowadays, it is used to measure attitude towards a certain stimulus.
