<span>A hypothesis is testable when you can create an experiment to study the proposition contained within the hypothesis. For example, the hypothesis ‘Santa travels slower than a unicorn’ is testable in theory by measuring the speeds of both, but it is not truly testable because neither exists in reality.</span>
Terminal velocity is the velocity at which a falling body experience
when its weight is equal to the force resistance of force opposing the
fall.
At terminal velocity the acceleration of the body is zero,
which implies that the value of the this velocity is a uniform.
Answer:
Explanation:
P = Pressure = 
V = Volume = 1 cm³
n = Amount of substance
N = Number of atoms
= Avogadro's constant = 
R = Gas constant = 8.314 J/k mol
T = Temperature = 273.15+20 = 293.15 K
From the ideal gas law
The number of atoms is
Max ang. speed(u) = 18 rad/s
final ang. speed(v) = 0
ang. displacement(s) = 220 rad
ang. acceleration = (v^2 - u^2)/2s = -18^2 / 2*220 = -0.7364 rad/s^2
v = u +at
0 = 18 - 0.7364t
t = 18/0.7364
t = 24.44 seconds
Answer:
A jar of mixed nuts is the correct answer.
Explanation:
A heterogeneous mixture is a type of mixture that is not uniform in the appearance and composition varies throughout.
The heterogeneous mixture consists of multiple phases.
A jar of mixed nuts is an example of the heterogeneous mixture because they do not have a uniform composition component differ in proportion and they do not mix, instead, they form two different layers and they can be easily separated.
