Why does the frequency of a wave increase as the wavelength decreases? A) because the wave speed remains constant B) because the

amplitude of the wave must remain constant C) because the frequency must get larger to increase the speed D) because the wavelength must get smaller to decrease the speed Eliminate

Answer: A)

Explanation: A wave with a constant speed is inversely proportional to the wavelength. So, the wavelength would decrease as the frequency of wave increases.

Answer:

A) because wave speed remains constant.

Explanation:

The wave speed of a wave in a medium depends on the nature of the medium.

For transverse waves in a string given by,

v = \sqrt{\frac{T}{m}}, T = tension , m = linear density

For longitudinal waves in a solid,

v = \sqrt{\frac{ξ}{ρ}},  ξ = modulus of elasticity, ρ = density

Like wise for different media, different properties and parameters govern the speed of waves moving through them.

It is important to mind in v = fλ ,f or λ does not influence on speed of wave in a medium but shows how f and λ varies as a wave propagate in a medium(/media).

If your body is dehydrated, the control center in the brain will stimulate the release of a hormone which causes the reabsorptio
Yanka [14]

Answer:

It is an example of negative feedback mechanism

Explanation:

Negative feedback mechanism is the process by which the output of a system, process or mechanism is fed back into the input in order to reduce the error in the system.

In the system described in this question, the reabsorption of water is the output, a feedback signal is sent to the control center, which is the input in order to control the release of the hormone responsible for reabsorption of water into the blood.

calculate the efficiency of a light bulb that had an input of 400 j transfers 100j as a light and 300j as heat.​
beks73 [17]
Efficiency = useful energy out / total energy in x 100
= 100/400 x 100
=0.25 x 100
= 25%

A rectangular gasoline tank can hold 50.0 kg of gasoline when full. What is the depth of the tank if it is 0.500-m wide by 0.900
sweet-ann [11.9K]

Answer:

0.16 m

Explanation:

A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).

50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³

The volume of the rectangular tank is:

volume = width × length × depth

depth = volume / width × length

depth = 0.074 m³ / 0.500 m × 0.900 m

depth = 0.16 m

In a neutral atom the number of electrons equals the number of what part of what other part
koban [17]

Protons

Explanation:

In a neutral atom, the number of electrons equals the number of protons in the atom.

  •  Electrons are the negatively charge particles in an atom
  • Protons carry positive charge.
  • Neutrons do not carry any charges.

Protons and neutrons are contained in the nucleus of an atom they determine the mass number of the atom.

In a neutral atom, the number of protons and electrons must be the same.

A charge atom called an ion is one that has lost or gained electrons.
