Let's find the relationship


- So if frequency increases Energy of the wave increases and wavelength decreases and vice-versa
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
This effect is explained by increased chain entanglements at higher molecular weights. Increasing the degree of crystallinity of a semicrystalline polymer leads to an enhancement of the tensile strength. Deformation by drawing increases the tensile strength of a semicrystalline polymer.
20 N north because He is pushing it 20 newtons north.
Fnet = (mass) (acceleration)
= 11 kg x 3.7m/s^2
= 41 N
