The answer would be A because as you get further away from sound the intensity decreases.
Answer:
pressure of solid depends on:
1/magnitude of the force
2/contact area
pressure in solid depends on:
1/depth inside the fluid.
2/density of the fluid.
3/Acceleration due to gravity.
Explanation:
1/magnitude of the force:the pressure is directly proportional to the magnitude of the force(thrust). The larger the force, the higher is the magnitude of pressure on the surface.
2/Contact area: the pressure is inversely proportional to the surface area of contact. The larger the contact area, lower is the magnitude of the pressure.

Answer:
4.245s
Explanation:
Given that,
Hypothetical value of speed of light in a vacuum is 18 m/s
Speed of the car, 14 m/s
Time given is 6.76 s, and we're asked to find the observed time, T
The relationship between the two times can be given as
T = t / √[1 - (v²/c²)]
The missing variable were looking for is t, and we can find it if we rearrange the formula and make t the subject
t = T / √[1 - (v²/c²)]
And now, we substitute the values and insert into the equation
t = 6.76 * √[1 - (14²/18²)]
t = 6.76 * √[1 - (196/324)]
t = 6.76 * √(1 - 0.605)
t = 6.76 * √0.395
t = 6.76 * 0.628
t = 4.245 s
Therefore, the time the driver measures for the trip is 4.245s
The mineral with Mohs hardness would be scratched because the mineral with Mohs 7 hardness is stronger than the Mohs 5 mineral. Eventually, that mineral would turn into dust if you kept rubbing it.
