Answer:
this sound wave get to the other by either undergoing either reflection,absorption or transmission
Explanation:
When a sound wave meets an obstacle, some of the sound is reflected back from the front surface and some of the sound passes into the obstacle material, where it is absorbed or transmitted through the material like the building walls
Thus, Reflection and absorption are dependent on the wavelength of the sound. Hence percentage of the sound transmitted through an obstacle depends on how much sound is reflected and how much is absorbed.
F=ma
f?
m=1300kg
a=1.07m\s squared
f=1300kg x 1.07=1391N
Answer:
Explanation:
The longer arm means the force needed to create the required torque is lower than for the short handled spanner.
τ = FR
Answer:B
Explanation:
Given
mass of sledge=82 kg
Force on sledge=160 N
degree
force has two component sin and cos
Normal reaction
True.
Density = mass / volume, Unit = g / cm³.
This is a common unit because of its affiliation with the SI unit and because that also our popular liquid which is water = 1 g/cm³
