Answer:
v = 72.54 m/s
Explanation:
We have,
Length of a guitar string is 0.62 m
Frequency of a guitar string is 234 Hz
For guitar string,
The velocity of the wave in the string is given by :
So, the velocity of the waves in the string is 72.54 m/s.
1) Vacuum tube
2) silicon
3) integrated, I.C.s
4) this one is worded weird. Transistors are the main part of voltage regulators but they use (require) diodes and capacitors, too. And they are all put onto a microchip in the power distribution section. sorry for the long explanation.
5) away from
6) directly, inversely
Like a grandfather clock,
A pendulum = a string with a weight(can be anything from a coin to a ring to a ball) is on the end, the pendulum swings back and forth losing a little bit of energy every swing until it comes to a complete stop
Answer:
E = 4410 J
Explanation:
The net energy change is equal to the change in potential energy
ΔPE = mgΔh = 50(9.8)(16) = 7,840 J
However some of that energy went into the stretch of the spring.
that stretch is found setting the spring force equal to the weight
kx = mg
x = 50(9.8)/35 = 14 m
so energy stored in the spring is
PS = ½kx² = ½(35)(14²) = 3,430
energy lost to friction is 7840 - 3430 = 4,410
