Answer:
Frequency = 260 Hz and wavelength = 1.31 m
Explanation:
Given that,
A hammer begins vibrating back and forth at approximately 260 cycles per second.
(a) The frequency of an object is the number of vibrations per unit time. The frequency of the sound wave is 260 Hz.
(b) The speed of sound in air is 343 m/s. So,
Hence, this is the required solution.
Industrially biomass, living or recently experienced obtain fuel from biological material or by using other industrial purposes are related. Widely, with the goal of obtaining biofuels fibers with cultivated plants, heat and chemicals used to obtain the means of animal and vegetable products. Biomass, organic waste can be burned as a fuel composition. However, geographical impact modified with, coal, organic materials such as oil-free. Are usually measured by dry weight
Has an Environmental Impact. Perhaps the largest disadvantage of hydroelectric energy is the impact it can have on the environment.
It Displaces People.
It's Expensive.
There are Limited Reservoirs.
There are Droughts.
It's Not Always Safe
This is the equation for elastic potential energy, where U is potential energy, x is the displacement of the end of the spring, and k is the spring constant.
