Plz will make your answer !
true or false. the electromagnetic spectrum can be described in terms of wave energy, frequency, and wavelength.
question 3 options:
true because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave.
false because the electromagnetic spectrum is about radiation, not waves.
true because the electromagnetic spectrum is ordered based on wave energy, which is described on a wave as wavelength and frequency.
false because energy, wavelength, and frequency are only characteristics of mechanical waves.
an x-ray technician will place a lead cloth over parts of your body when taking an x-ray to protect your cells from being damaged. why do x-rays have the potential to harm your body but radio waves do not?
question 6 options:
x-rays have a much shorter wavelength than radio waves, and therefore carry more energy that can be transferred to your body.
radio waves are shorter than x-rays and therefore weaker in strength..
x-rays have a taller wavelength than radio waves as shown in the diagram, so they are more harmful.
radio waves have longer wavelengths than x-rays and therefore carry more energy than x-rays.

American eels (anguilla rostrata) are freshwater fish with long, slender bodies that we can treat as uniform cylinders 1.0 m long and 10 cm in diameter. an eel compensates for its small jaw and teeth by holding onto prey with its mouth and then rapidly spinning its body around its long axis to tear off a piece of flesh. eels have been recorded to spin at up to 14 revolutions per second when feeding in this way. although this feeding method is costly in terms of energy, it allows the eel to feed on larger prey than it otherwise could. 1.a field researcher uses the slow-motion feature on her phones camera to shoot a video of an eel spinning at its maximum rate. the camera records at 120 frames per second. through what angle does the eel rotate from one frame to the next? 2. the eel is observed to spin at 14 spins per second clockwise, and 10 seconds later it is observed to spin at 8 spins per second counterclockwise. what is the magnitude of the eels average angular acceleration during this time? 3. the eel has a certain amount of rotational kinetic energy when spinning at 14 spins per second. if it swam in a straight line instead, about how fast would the eel have to swim to have the same amount of kinetic energy as when it is spinning? 4.a new species of eel is found to have the same mass but one-quarter the length and twice the diameter of the american eel. how does its moment of inertia for spinning around its long axis compare to that of the american eel?
