<h3><u>Answer;</u></h3>

B. the sound gets louder

<h3><u>Explanation;</u></h3>
  • <em><u>Sound waves are examples of mechanical longitudinal waves.</u></em> Mechanical waves because they require a material medium for transmission. Longitudinal waves because the vibration of particles in sound waves is parallel to the direction of wave motion.
  • <em><u>As the energy of a sound wave increases, then the sound becomes louder.</u></em> The higher the energy of a wave the higher the amplitude of sound waves. Therefore, <em><u>greater amplitude of sound waves means the waves possess higher energy and thus greater intensity and therefore, the sound will be louder.</u></em>

The sound gets louder, like hitting a metal pole on a thin metal beam, the energy increases as the sound does.

Why is it correct to say that the linear electron flow of the light reactions directly captures energy in nadph but only indirec
denis-greek [22]

Answer:

he electron is directly transferred to NADP+ to NADPH, but electron flow is used to generate a proton gradient for ATP synthesis. Electron is not directly transferred to ATP

NADP= Nicotin amide adenine dinucleotide phosphate

NADPH =Nicotinamide adenine dinucleotide phosphate is the reduced form of  NADP

therefore electron is not directly transferred to ATP

OLEGan [10]

A square loop whose sides are long is made of copper wire of radius , given the resistivity of copper is . if the magnetic field perpendicular to the loop changes at a constant rate of I = 14.029 mA.

The basic characteristic of a substance that measures how effectively it resists an electric current is called electrical resistance. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. Electrical resistance is a basic property of a material that measures how strongly it resists an electric current. The SI unit for electrical resistance is the ohmmeter.

We use magnetic field as a tool to describe how the magnetic field is distributed in the space around and inside something of a magnetic nature. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. An ohmmeter is a unit of electrical resistance in the SI system.
