The output waveforms after passing through the transformer actually depend on the type of transformer used. It could either be a step-up transformer (steps voltage up), or a step-down transformer (steps voltage down). Both transformers have an output voltage in a form of a sine wave.
Answer:
Work is done by the heart on the blood during this time is 0.04 J
Explanation:
Given :
Mass of blood pumped, m = 80 g = 0.08 kg
Initial speed of the blood, u = 0 m/s
Final speed of the blood, v = 1 m/s
Initial kinetic energy of blood is determine by the relation:
Final kinetic energy of blood is determine by the relation:
Applying work-energy theorem,
Work done = Change in kinetic energy
W = E₂ - E₁
Substitute the suitable values in the above equation.
W = 0.04 J
While breaking glass with sound is an interesting trick it really takes a lot of effort vibrations diminishes do you to energy being carried away by the sound waves.
Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.
