Answer:
Options A, B, and C are all possible.
Explanation:
We know that the instantaneous velocity of the dog at 3:14PM is possitive to toward the flowers. But what about the acceleration to toward the flowers?
If the dog is decreasing speed at 3:14PM, it means that acceleration is negative toward the flowers, hence (since F=ma) the net force points away from the flowers.
If the dog is increasing speed at 3:14PM, it means that acceleration is positive toward the flowers, hence (since F=ma) the net force points toward the flowers.
If the dog is not increasing nor decreasing speed at 3:14PM, it means that acceleration is 0, hence (since F=ma) the net force is null and it does not point neighter to toward the flowers nor away from the flowers. This happens when the forces acting on the dog are equal to both sides.
How do you mean? I mean, physic professors teach physics...
I belive that they are undalanced
The speed of a periodic wave disturbance is 2.45 m/s.
<u>Explanation:</u>
Sound waves travel as sinusoidal nature. And the distance between the two successive crests or troughs are determined as the wavelength of the sound wave.
Similarly, the measure of number of complete cycles in a given time is defined as frequency of sound wave. The speed of any wave is determined as the product of wavelength of transmission of wave and frequency of that wave.
Thus,

So,

= 2.45 m/s.
Thus, the speed of periodic wave disturbance is 2.45 m/s.
H2SO4 is a chemical symbol for sulfuric acid. Converting this compound to HSO4 or the hydrogen sulfate ion means that it has lost one of its protons. With this we can conclude that H2SO4 is a Bronsted-Lowry acid.
