Answer:
a) v = 1524.7 m/s
b) T = 8.47*10^-4 s
λ = 1.29 m
Explanation:
a) First, in order to calculate the speed of the sound wave, you take into account that the velocity is constant, then, you use the following formula:
d: distance traveled by the sound wave, which is twice the distance to the ocean bottom = 2*324 m = 648 m
t: time that sound wave takes to return to the sub = 0.425
hence, the speed of the sound wave is 1524.7 m/s
b) Next, with the value of the velocity of the wave you can calculate the wavelength of the wave, by using the following formula:
f: frequency = 1.18*10^3 Hz
And the period is:
hence, the wavelength and period of the sound wave is, respectively, 1.29m and 8.47*10^-4 s

Answer:
Petroleum is a nonrenewable resource. This being because it is a natural gas that take millions of years for it to reform which means each part of it is a once in a lifetime use.
Answer:
864 mT
Explanation:
The magnetic field due to a long straight wire B = μ₀i/2πR where μ₀ = permeability of free space = 4π × 10⁻⁷ H/m, i = current in wire, and R = distance from center of wire to point of magnetic field.
The magnitude of magnetic field due to the first wire carrying current i = 2.70 A at distance R which is mid-point between the wires is B = μ₀i/2πR.
Since the other wire also carries the same current at distance R, the magnitude of the magnetic field is B = μ₀i/2πR.
The resultant magnetic field at B is B' = B + B = 2B = 2(μ₀i/2πR) = μ₀i/πR
Now R = 2.50 cm/2 = 1.25 cm = 1.25 × 10⁻² m and i = 2.70 A.
Substituting these into B' = μ₀i/πR, we have
B' = 4π × 10⁻⁷ H/m × 2.70 A/π(1.25 × 10⁻² m)
B = 10.8/1.25 × 10⁻⁵ T
B = 8.64 × 10⁻⁵ T
B = 864 × 10⁻³ T
B = 864 mT
A diode has two terminals. The positive side is called the anode, and the negative one is called the cathode.
