Direction.
And value that is not scalar has both magnitude and direction; such as 3.5 m/s (magnitude) East (Direction).
The result of
changing a physical sound wave into an analogous electrical signal using a
transducer (such as a microphone) is called analogue audio. In this system, the rapid electrical level is
directly proportional to the rapid air pressure taken by the transducer. The analogue
signal is then augmented and can be kept on an analogue medium such as tape or transformed
further into a succession of discrete mathematical numbers. The advantages of
using this device is that it yields a subtle sound and is pleasing to the ear
by pushing the signal level and overdriving it. But the disadvantages are
editing it would be tedious and prone to degradation.
Answer:
x = 8.74m
Explanation:
Hello! Let's solve this!
Given a mass m = 0.44kg
v = 4m / s
F = 8N
y = 20m
Force on the rocket
F '= F * - (mg) = m * a
We cleared to
a = (F * (- mg)) / m = (F / m) * (- g)
The rocket will accelerate upwards at a time t given by x = v * t
We cleared t
t = x / v
From kinematics we have to
y = (1/2) * a * t2
We replace a and t
y = (1/2) * (F / m) * (- g) * (x / v) 2
We clear x that is the incognita.
x = 8.74m
