The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, <span>the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.</span>
To the right, if you push something left the friction is to the right
Answer:
Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. ... Scientists can determine how long ago an organism died by measuring how much carbon-14 is left relative to the carbon-12.
Explanation:
(a) The average speed must you have for the second half of the trip to meet your goal is 8 km/h.
(b) The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.
<h3>
What is average velocity?</h3>
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
average velocity = total distance / total time
v = (d)/(0.5d/v₁ + 0.5d/v₂)
where;
- v is the average velocity
- v₁ is the average velocity during the first half
- v₂ is the average velocity during the second half
90 km/h = (d) / (0.5d/48 + 0.5d/v₂)
90(0.5d/48 + 0.5d/v₂) = d
0.9375d + 0.5d/v₂ = d
d(0.9375 + 0.5/v₂) = d
0.9375 + 0.5/v₂ = 1
0.5/v₂ = 0.0625
v₂ = 0.5/0.0625
v₂ = 8 km/h
Thus, the average speed must you have for the second half of the trip to meet your goal is 8 km/h.
The value obtained (8 km/h) is not reasonable for the second half of the distance since the first half is 48km/h.
