Answer:
a. Tension of the strings
Explanation:
The koto is a pluckedstring instrument. In these instruments, the sound is obtained causing the vibration in several strings. Therefore, its sound depends on the thickness, extension and tension of the strings. The lower the tension the deeper the sound will be.
D is not a scientific experiment.
Answer:
A circuit with two 10 ohm resistors connected in series.
Explanation:
The formula for the equivalent resistance for resistors in parallel is
So if R1=R2= 10
The formula for the equivalent resistance for resistors in series is
Rt = R1 + R2 So Rt= 10 + 10 = 20
To solve this problem we will apply the concepts related to energy conservation. For this purpose we will have that all the changes occurred in the energy change will be equivalent to the change in the potential and kinematic energies of the body. At the same time we will consider that the change in the final energy of the system will be reflected in the work of the system, therefore,
Here,
F = Force
m = mass
v = Velocity
h = Height
d = Distance
Replacing we have,
Therefore the launch energy is 365061ft-lb
