Answer:
(a) 
(b) 
Explanation:
Given data
The source is 1.00 μW
The point is 3m away from the point source
For Part (a)
The intensity at a certain distance from a point source that emits sound wave is given as:
For Part (b)
The Sound level is given by
β=(10dB)×log(I/I₀)
Where
I₀=1×10⁻¹²W/m²
Substitute the given values to find Sound level
So
Answer:
they are constantly bouncing everywhere and creating preasure
Explanation:
Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.
<h3> What is the law of conservation of energy?</h3>
According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
Transformations that occur as an engine runs to power a car is;
1. Chemical energy of fuel transforms into thermal energy.
2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.
3. Thermal energy transforms into kinetic energy to help to run the car.
Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.
Hence, transformation 3 should Tracy removed from the list.
