Multiplying the power of any signal by 5 can be described as
an increase of 6.99 dB .
If the whistle blew at 70 dB initially, and its sound power became
multiplied by 5, and the whistle and the listener both stayed in
the same places, then the listener would tell you that the whistle
was now blowing at 76.99 dB .
(More likely, he would report "77 dB" as he held his ears and winced.)
Answer:
delay or stifle the emergence of the perspective
An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice . The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other.
Answer:
D
The toy car would travel farther because more potential energy would be transferred into kinetic energy
Explanation:
Increase in angle will lead to increase in height.
Since potential energy = mgh
Definitely potential energy will also increase.
According to conservative of energy, the maximum potential energy is equal to the maximum kinetic energy. Therefore, the toy car would travel farther because more potential energy would be transferred into kinetic energy.
