The amplitude and wavelength are measured in meters while frequency is measured in decibels.

<h2>Units of measurement:</h2>
  • Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.
  • Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.
  • Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.
  • Wave speed: It is measured in m/s.
  • Loudness: The loudness of the sound is measured in decibels.

Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

The practice of science can answer only scientific questions. And scientific questions guide the design of investigations. What
meriva

The scientific question can be supported by evidence that must be true of the possible answers to a scientific question. Option D is correct,

<h3>What is a Scientific hypothesis?</h3>

A scientific hypothesis must meet two criteria, A scientific hypothesis must be testable, and a scientific hypothesis must be falsifiable The basic idea of a hypothesis is that there is no predetermined outcome.

For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation.

Only scientific questions may be answered by scientific activity. The design of the research is also influenced by scientific issues.

The scientific question can be supported by evidence that must be true of the possible answers to a scientific question.

They are accurate regarding the scientific question and can be substantiated by proof.

​

Hence option D is correct.

A 2.5-cm-diameter parallel-plate capacitor has a 2.2 mm spacing. The electric field strength inside the capacitor is 6.0×104 V/m
vladimir2022 [97]

Explanation:

The given data is as follows.

     Separation between two plates, d = 2.2 mm = 2.2 \times 10^{-3} m

     Electric field strength inside the capacitor, E = 6.0 \times 10^{4} V/m

Therefore, we will calculate the potential difference across the capacitor as follows.

              V = Ed

                  = 6.0 \times 10^{4} V/m \times 2.2 \times 10^{-3} m

                  = 1.32 V

Thus, we can conclude that the potential difference across the given capacitor is 1.32 V.

Placing the north pole of a magnet near the south pole of another magnet results in:
MakcuM [25]

Answer:

An attractive force between the magnets. A is the correct answer if it was the north pole facing another north pole magnet the answer would have been a repulsive force between the magnets because the north pole of a magnet does not attract instead it separates from each other which is a repulsive force the best answer is A.

Explanation:

the southern pole of a magnet is a positive force while the northern pole of a magnet is negative .

Note: Magnet can attract each other only when they are facing the opposite directions a north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away.
