Answer:
I believe it's A. An installment credit has an interest rate, repayment terms and fees, and fixed payment.
Answer:
Explanation:
We shall find the volume of stored gas at atmospheric pressure .
P₁ V₁ = P₂ V₂
15.5 x 10⁶ x .02 = 10⁵ x V₂ ( atmospheric pressure is 10⁵ Pa )
V₂ = 3.1 m³
volume of one balloon = 4/3 x π r³ , r is radius of balloon
= 4/3 π x .11³
= .050658 m³
no of balloon = total volume to be filled / volume of one balloon
= 3.1 / .050658
= 61 .2
= 61
Answer:
A. 50 Hz
B. 2 m/s
Explanation:
We'll begin by converting 20 ms to s. This can be obtained as follow:
1000 ms = 1 s
Therefore,
20 ms = 20 ms × 1 s / 1000 ms
20 ms = 0.02 s
Next, we shall convert the value of the wavelength (i.e 4cm) to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
4 cm = 4 cm × 1 m / 100 cm
4 cm = 0.04 m
A. Determination of the frequency.
Period (T) = 0.02 s
Frequency (f) =?
f = 1 / T
f = 1 / 0.02
f = 50 Hz
Therefore, the frequency of the wave is 50 Hz
B. Determination of the velocity.
Wavelength (λ) = 0.04 m
Frequency (f) = 50 Hz
Velocity (v) =?
v = λf
V = 0.04 × 50
v = 2 m/s
Therefore, the velocity of the wave is 2 m/s
