Answer:
C
Explanation:
The density is what determines if it will float. Lower densities float, while higher densities sink. Density takes mass and volume into account.
I am not entirely sure but i believe the answer is C scupture
<u>Answer </u>
Wind
Water movement
A hill
<u>Explanation. </u>
The question does not specify it is the acceleration of what is to be accelerated. So my answer will be general. Acceleration is the change of velocity with time.
Wind can cause acceleration of sound. If the sound is travelling in the direction of sound, its speed wound increase. The reverse is also true.
Water movement can also cause acceleration. When a bout is moving in the direction of water movement, then it will be expected that the resultant speed of the bout to be higher. If the bout was moving against the water movement, its speed would be decreased.
A hill would reduce the speed of a moving vehicle. This is also an acceleration that is negative (deceleration).
A stop light and a flat road cannot cause acceleration.
Answer:
130.2dB
Explanation:
The formula for determining the intensity of a wave is expressed as
Where P is the power in watts, and A is the area of the sphere formed by the wave
Data given
Power,P=3.65*10^5W
distance,d=52.7
Hence since the distance represent the radius, we can determine the area of the sphere formed
The intensity can be computed as
we can convert to decibel
