When a crest-trough meet the interference produced will be destructive in nature hence they both will cancel out and the amplitude produced will be equal to zero hence the loudness will reduce to zero.
Answer:
a= 0.22 m/s²
Explanation:
Given that
M = 3.5 kg
θ = 30°
m = 1 kg
μ= 0.3
The force due to gravity
F₁= M g sinθ
F₁=3.5 x 10 x sin 30
F₁= 17.5 N
F₂ = m g
F₂ = 1 x 10 = 10 N
The maximum value of the friction force on the incline plane
Fr = μ M g cosθ
Fr = 0.3 x 2.5 x 10 cos30°
Fr= 6.49 N
Lets take acceleration of the system is a m/s²
F₁ - F₂ - Fr = (M+m) a
17.5 - 10 - 6.49 = (3.5+1)a
a= 0.22 m/s²
Conservation law, also called law of conservation, in physics, several principles that state that certain physical properties (i.e., measurable quantities) do not change in the course of time within an isolated physical system
b. is equally as toxic as carbon monoxide (CO).
Explanation:
Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.
The gas is a product of combustion in blast furnances, coke ovens, e.t.c
- Just like carbon monoxide, they are blood agents that are toxic in the body
- Prolonged exposure to hydrogen cyanide can lead to death eventually.
- The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
- It is listed as one of the dangerous chemical weapons.
