Answer:
1/12
Step-by-step explanation:
<span>The concept goes to the idea of falsification. The null hypothesis is based on the concept that there is no statistically significant difference between the two factors being studied. The outcome, when it is measured, seeks to falsify this statement: if it does not, then it simply does not falsify the null hypothesis. However, it does not mean that the null hypothesis is accepted as correct: it may simply mean that there are other, unstudied factors at play that were not tested and could have some sort of effect.</span>
Answer:
all you need to do is multiply all of the numbers together.
Step-by-step explanation:
Answer:
An object moving along the x-axis is said to exhibit simple harmonic motion if its position as a function of time varies as
x(t) = x0 + A cos(ωt + φ).
The object oscillates about the equilibrium position x0. If we choose the origin of our coordinate system such that x0 = 0, then the displacement x from the equilibrium position as a function of time is given by
x(t) = A cos(ωt + φ).
A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction. Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The velocity of the object as a function of time is given by
v(t) = dx(t)/dt = -ω A sin(ωt + φ),
and the acceleration is given by
a(t) = dv(t)/dt = -ω2A cos(ωt + φ) = -ω2x.
