<span>This problem can be solved by the formula used to find resistance. The formula is R=V/I which basically means divide the Voltage by the Current to find the Resistance in an object. Ohm's law.</span>
Answer:
<em> 30720 oscillation.</em>
Explanation:
Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.
<em>From the question,</em>
<em>The frequency of the string set is 512 Hz,</em>
<em>These means that the spring set complete 512 oscillation in one seconds</em>
<em>I.e</em>
<em>if its completes in one seconds 512 oscillation.</em>
<em>Then, in one minutes, it will complete x oscillation.</em>
<em>x = 512×1min/1seconds</em>
<em>But 1 minutes = 60 seconds</em>
<em>x = 512×60/1</em>
<em>x = 30720 oscillation.</em>

Answer:
u= 755 m/s
Explanation:
Lets take
Velocity of bullet = u m/s
The velocity of system after collision ,v= 5 m/s
m= 10 g = 0.01 kg
M= 1.5 kg
From linear momentum conservation( because there is no any external force on the system)
Pi= Pf
m u = ( m +m) v
0.01 x u= (1.5 + 0.01) x 5
u= 755 m/s
