Moving along the elevtromagnetic spectrum from low frequency to high frequency, what , if anything, happens to the wavelength? wavelength get longer

wavelength remains constant

the wavelengths get shorter

wavelength eventually disappear altogether

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

the answer would be 32*f

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

gravitational energy

electrical energy

kinetic energy

ligh energy
