Answer:
v = 1.224 m/s
Explanation:
given,
distance between the two successive maxima = 1.70 m
number of crest = 8
time = 11 s
frequency is equal to number of cycle per secod
velocity of wave
v = f x λ
v = 0.72 x 1.70
v = 1.224 m/s
Hence, the wave speed is equal to v = 1.224 m/s
Answer:
Melting
Explanation:
The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance.
Answer & Explanation:
Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. Scientists classify them by their frequency or wavelength, going from high to low frequency (short to long wavelength).
The smallest parts that make up different types of matter are called atoms.
Atoms are tiny elements that are made up of literally everything on earth. <span />
