Assume your sampling frequency (fs) is 500 Hz. If you want to capture the 50Hz signal for 5 seconds, calculate the number of sam
belka [17]

Answer:

N = 2500

Explanation:

By definition, the sampling frequency (fs) is:

f_{s} = N / T

<em>where N: is the number of samples and T: is the time</em>

Hence, the number of samples at the sampling frequency, 500 Hz, to get 5 seconds of data is:

N = f_{s} \cdot T = 500 s^{-1} \cdot 5 s = 2500  

I hope it helps you!

A car going 50mph accelerates to pass a truck. five seconds later the car is going 80mph. calculate the acceleration of the car.
gizmo_the_mogwai [7]
Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. <span>Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:
</span>
acceleration = v - v0 / t
acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s
acceleration = 1.67 x 10^-3 m / s^2 

Therefore, the acceleration of the car is 1.67 x 10^-3 m / s.

A series of evenly timed pulses create a wave that can be described as a _______<br><br> wave.
son4ous [18]

Answer:

Periodic

Explanation:

A periodic (or repetitive) wave has continuously repeating pattern with characteristics such as amplitude, wavelength and frequency. In a periodic wave, a series of pulses that are evenly timed would be created. In other words, the wave pattern in a periodic wave repeats at regular intervals.

An example of a periodic wave is the sound from the strings of a violin.`

This position-time graph describes an object's motion. Use it to determine the
kirza4 [7]

We're happy that you're asking for the "displacement", because displacement is simply the straight-line distance between the start-point and end-point, and we don't care about any of the motions or gyrations along the way.

From the graph:

-- The location of the object at time-zero, when time begins, is  10 meters.

-- The location of the object after 6.0 seconds is  4 meters.

-- The distance between the start-point and end-point is

(final location) - (initial location)

-- So Displacement = (4 meters) - (10 meters)

<em>Displacement = -6 meters</em>
