Answer:
Speed = 0.296m/2
Period = 0.203 s
Explanation:
If by 'long' you mean the wavelength of the waves, then the wavelength 
.
The frequency 
of the waves is 14.8 waves every 3 seconds or
.
Now the relationship between wavelength 
, frequency and speed 
of the waves is:
We put in the values and 
and get:
Now the period 
is just the inverse of the frequency, or
The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage.
Power: is the amount of energy transferred or converted per unit time.
The velocity of pluck 1 is 12 m/s west.
<h3>What is the conservation of momentum?</h3>
The principle of the conservation of the linear momentum states that momentum before collision is equal to momentum after collision.
Now given that;
m1u1 + m2u2 = m1v1 + m2v2
(0.1 * 15) - (0.1 * 12) = 0.1* v + (0.1 * 15)
1.5 - 1.2 = 0.1v + 1.5
0.3 - 1.5 = 0.1v
v = -1.2/0.1
v = - 12 m/s
Hence, the velocity of pluck 1 is 12 m/s west.

Answer:
The work done in winding the spring gets stored in the wound up spring in the form of elastic potential energy (i.e potential energy due to change in shape). ... During this process, the potential energy stored in it gets converted to kinetic energy. This turns the wheels of the toy car.
