I don’t understand this launguage at all lol.I’m sorry.
Answer:
zero times greater
Explanation:
Coffee's pH level is 5
Pure water's pH level is 7
Answer:
(a) average velocity = 17.6 m/s
(b) when t = 0, v = 0
when t = 4, v = 19.2 m/s
when t = 8, v = 28.8 m/s
(c) after starting from rest, the car will be at rest again in 20 s
Explanation:
Given;
x(t)=bt²−ct³, substitute the given values and the equation will become;
x(t)=3t²−0.1t³
(a)average velocity = total distance / total time
total distance, x(t) = 3t²−0.1t³
x(8) = 3t²−0.1t³
X(8) = 3(8)² - 0.1(8)³
X(8) = 140.8 m
total time = 8 s
average velocity = 140.8 / 8
average velocity = 17.6 m/s
(b) instantaneous velocity = dx / dt
dx / dt = 6t - 0.3t²
when t = 0
v = 0
when t = 4 s
v = 6(4) - 0.3(4²) = 19.2 m/s
when t = 8 s
v = 6(8) - 0.3(8²) = 28.8 m/s
(c) the velocity is zero at dx / dt = 0
6t - 0.3t² = 0
t(6 - 0.3t) = 0
t = 0 or 6 - 0.3t = 0
t = 0 or 0.3t = 6
t = 0 or t = 6 / 0.3
t= 0 or t = 20 s
After starting from rest, the car will be at rest again in 20 s
Answer:
the comparison and contrasting the feature, properties and behaviors of the different planetary objects and the diverse worlds.
comprehend theories of the formation, origin of the different planets
Explanation:
The comparative planetology is the space science that deals with study of the the comparison and contrasting the feature, properties and behaviors of the different planetary objects and the diverse worlds.
The comparative planetology helps the astronomers to comprehend theories of the formation, origin of the different planets.
Answer:
The resistors in parallel.
Explanation:
If you have 2, 3 or infinite resistors in parallel (that means when both of their terminals are respectively connected to each terminal of the others resistors), they all have the same potential difference even when they have different values. Of course that means if the resistor value increases, the current decreases since V=I.R, where V is a constant in the parallel resistors.
