<u>Answer</u>
108 N
<u>Explanation</u>
The centripetal force is the force that keeps an object in a circular motion.
Centripetal force= mω²r
Where m is the mass, ω is angular velocity and r is the length of the string.
But ω = v/r. Where v is the tangential speed.
∴ F = mω²r = mv²/r
F = (1.5 × 6²) / 0.5
=
= 108 N

Answer:
Increases
Explanation:
Since power P=IV
Then it means when current increases, the power increases hence brightness increases. I represent current, P is power and v is voltage.
Current of capacitor when in series connection is given by
where I is current across capacitor, f is frequency, C is capacitance and v is voltage across capacitance. From this second formula, it is evident that an increase in capacitance increases the current across the capacitor. Therefore, if current increases, power also increases leading to an increase in brightness
Answer:
72.04 dB.
Explanation:
The intensity level of 60dB corresponds to the sound intensity given by the equation
where
solving for we get:
Now, when 16 violins are playing the intensity becomes
which on the decibel scale gives
.
Thus, playing 16 violins together gives the intensity level of 72 dB.
