Answer:
d. boost frequencies below 80 Hz.
Explanation:
Low frequency sound appear to be soothing to mind. It is called bass . bass instruments play low frequency notes. But to produce low frequency note , the size of musical instruments have to be increased which increases its cost.
Any instrument which boosts low frequency are therefore costly . They are accompanied by air amplifier.
When you have several resistors in parallel, their equivalent resistance is the reciprocal of the sum of their individual reciprocals.
When there are only two of them, it gets a lot easier. In that case, their equivalent resistance is equal to
(their product) divided by (their sum).
Equivalent = (7 x 93) / (7 + 93)
Equivalent = (651) / (100)
<em>Equivalent = 6.51 ohms </em>.
Answer:
A volcano that erupts frequently.
Explanation:
Both.
But the volcano that hasn't erupted in 100 years would probably be more dangerous because you wouldn't be prepared for its explosion as you would be for the one that erupts frequently.
Glad I could help!!
Answer:
μ = 0.724
Explanation:
maximum acceleration for SHM
a = ω²A
ω = 2πf
a = 4π²f²A
a = 4π²(1.50)²(0.080) = 7.106... m/s²
μ = F/N = ma/mg = a/g = 7.106/9.81 = 0.7243...
I'm cynical that a block can be cynical. Wassa madder, doesn't trust anyone?
