Answer:
to be seen correctly and throughly
In Mathematics and Physics, scalar is a quantity or a single number that shows the measurement of a medium in magnitude only (It does not include direction as vectors do); examples of scalars are voltage, mass, temperature, speed, volume, power, energy, and time.
Two examples of scalars I have used recently are Degrees Celsius to measure the temperature of my living room and Cubic Feet to measure the volume of my mug.
Answer:
magneto hydrodynamic( MHD) waves
Explanation:
The surface of the Sun transmits magneto hydrodynamic( MHD) waves to its atmosphere. These waves carry energy from the sun's surface to its atmosphere ( Corona) and heat up the atmosphere to such extent that its temperature rises to many time than that of the surface temperature of the Sun.
Answer:
two wavelength are present
as wavelength is counted either from crest to crest or trough to trough and there are only 2
