Why is the sound of a harp soft in comparison with the sound of a piano?

To explain: The reason for the difference between the sound of a harp and a piano.
Answer to Problem 40A
This is due to the material used in the making of two instruments.
Explanation of Solution
Introduction:
There is a difference between a piano and harp sound. This is based on the concept of vibrations produced in various materials. For example- the sound of music is dependent on the type of material from which it is produced.
The reason behind the soft sound of a harp is that its sounding board is made up of lighter material and the strings. When the fingers runs on its strings then soft sound is produced. In piano the large wood material is used. When the fingers run on its strings the sound vibration forced into its large wood size and due to this hard sound is produced.
Conclusion:
The soft and light material of a harp is responsible for its soft sound as compared to the hard sound of piano due to heavy mood material.

The bar rides on parallel metal rails connected through a 25-Ω, resistor (Figure 1), so the apparatus makes a complete circuit. Ignore the resistance of the bar and the rails. Please explain how to find the direction of the induced current.arrow_forwardFor each of the actions depicted, determine the direction (right, left, or zero) of the current induced to flow through the resistor in the circuit containing the secondary coil. The coils are wrapped around a plastic core. Immediately after the switch is closed, as shown in the figure, (Figure 1) in which direction does the current flow through the resistor? If the switch is then opened, as shown in the figure, in which direction does the current flow through the resistor? I have the answers to the question, but would like to understand the logic behind the answers. Please show steps.arrow_forward
