By what factor must you increase the intensity of a sound in order to hear a 1.0-dB rise in the sound level?

The right approach will be "1.3". A further explanation is given below.

Explanation:

As we know,

In Decibels, the change in sound volume will be:

=

Now,

According to the question,

⇒

By applying cross multiplication and putting the value of log, we get

⇒

⇒

⇒

we need to know the time interval during which the force acts. impulse of force = momentum change

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
