Answer:
The period is
Explanation:
From the question we are told that
The mass is 
The extension of the spring is 
The spring constant for this is mathematically represented as

Where F is the force on the spring which is mathematically evaluated as


So


The period of oscillation is mathematically evaluated as
substituting values
Answer:
acidic
Explanation:
because the lower you go on the scale the more acidic it is and the closer to the middle the more neutral it is
Answer:
i don't understand the hw
Answer:
B
Explanation:
it's converts electrical energy to mechanical energy.
By Boyle's law:
P₁V₁ = P₂V₂
70*8 = P<span>₂*4
</span>P<span>₂*4 = 70*8
</span>
P<span>₂ = 70*8/4 = 140
</span>
P<span>₂ = 140 kiloPascals.</span>
