A wave x meters long has a speed of y meters per second. The frequency of the wave isa. x/y hertz
c. y x hertz
b. y/x hertz
d. y x hertz

Answers

Answer 1
Answer: The correct answer is (b.) y/x hertz. That is because the formula to get the frequency is f =  v / w. The following values (v=y meters / second; wavelength = x meters) must be substituted to the equation, which leaves you y/x hertz.
Answer 2
Answer:

Answer:

b. y/x hertz

"One step in the manufacture of silicon wafers used in the microelectronics industry is the melt crystallization of silicon into a crystalline silicon ingot. This processis carried out within a special furnace. When the newly solidified ingot is removed from the furnace, it is assumed to have a uniform initial temperature of 1600 K, which is below the crystallization temperature. At this temperature, the thermal conductivity of silicon is 22 W/(m•K), the density is 2300 kg/m3, and the heat capacity is 1000 J/(kg•K). The hot solid silicon ingot is allowed to cool in air maintained at a constant ambient temperature of 30°C. The diameter of the silicon rod is 15 cm. End effects are considered negligible. The convective heat transfer coefficient is 147 W/(m2•K). What temperature will exist 1.5 cm from the surface of the ingot after a cooling time of 583 sec (9.72 min)?" Consider the rod as acylinder placed vertically.

Choose the false statement regarding resistance. A) Longer wires have less resistance. B) Electrical resistance produces heat. C) Resistance slows the flow of current. D) The larger the diameter of the wire, the less resistance.

Answers

The answer would be:

A. Longer wires have less resistance.

Here is why:

The statement is false because longer wires tend to have greater resistance. Look at the formula of resistance below:

R=(\rho L)/(A)

ρ = resistivity

L = length

A = cross-sectional area

As you can see Length of the wire is directly proportional to the resistance, which means as the Length increases, the Resistance increases.

Answer:

A. Longer wires have less resistance.

Cells with similar preferences are arranged closer together in the auditory cortex.

Answers

Cells with similar preferences are arranged closer together in the auditory cortex. That statement presented is True. Auditory cortex is in the temporal lobe. It processes auditory information in human and as well as other invertebrates. The neurons inside the auditory cortex are organized depends on the frequency of the sound.
