Answer:
More than 48%
Explanation:
If the interest is calculated monthly based on the outstanding balance, it leads to an effective annual rate of...
(1 + 4%)^12 - 1 = 60.1%... more than 48%
Answer:
The beats frequency measures approximately
4.4 kHz
Explanation:
The beat frequency arises from the original ultrasound frequency, 
, and the frequency of the sound reflected off the car, 
:
(1)
To calculate the frequency of the reflected sound, we apply the Doppler effect formula:
where
v = 340 m/s, the speed of sound
is the velocity of the car
is the frequency of the sound emitted
By substituting values,
Thus, the beat frequency (1) is
F = π/4 ρ d² v²
Explanation:
The formula for force is mass multiplied by acceleration:
F = ma
Acceleration is defined as the change in velocity over the change in time:
F = m Δv / Δt
Since there is no rebound effect, Δv is equal to v.
F = m v / Δt
Mass can be calculated as density multiplied by volume:
F = ρ V v / Δt
Flow rate describes the volume per time:
F = ρ Q v
Flow rate is determined by velocity multiplied by the cross-sectional area:
F = ρ (v A) v
This simplifies to F = ρ A v²
The area of a circle is calculated as pi times the square of the radius, or as pi/4 times the diameter squared:
F = ρ (π/4 d²) v²
Hence, F = π/4 ρ d² v²
Answer:
The book is titled Solid State or Condensed Matter
Explanation:
Response:
a. the lowest layer
Clarification:
This layer has the least refractive index, thus being the most rarefied.
