Answer: analog-to-digital

Explanation: Analog-to-digital converters as the name implies simply refers to components which are used to convert continuous analog signals into a discrete analog outputs so they it can be read and processed by a microprocessor. The microprocessors are unable to depict and read analog signals which could be gathered from sound, light or water wave sources. This wave sources are then sampled, processed and sorted into levels by the analog-to-digital converter before being sent to the microprocessor so that the waves can be read.

How do magnetic forces repel or attract?

Lerok [7]

“Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom”

“Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.”

The 2-kg collar is attached to a spring that has an un-stretched length of 3.0 m. If the collar is drawn to point B and releases

Bezzdna [24]

Complete Question

The image for this question is shown on the first uploaded image

Answer:

$v = 3.4 \ m/s$

Explanation:

From the question we are told that

The mass of the collar is $m = 2 \ kg$

The original length is $L = 3.0 \ m$

The spring constant is $k = 3.0 \ N/m$

Generally the extension of the spring is mathematically evaluated as

$e = 4 -3 = 1 \ m$

Now with Pythagoras theorem we can obtain the length from A to B as

$AB = \sqrt{5 ^2 + 4^2}$

$AB = 6.4 \ m$

The extension of the spring at B is

$e_b = 6.4 - 3 = 3.4 \ m$

According to the law of energy conservation

The energy stored in the spring at point A + the kinetic energy of the spring = The energy stored on the spring at B

$\frac{1}{2} * k * e + \frac{1}{2} * m* v^2 = \frac{1}{2} * k * e_b$

substituting values

$\frac{1}{2} * 3 * 1^2 + \frac{1}{2} * 2* v^2 = \frac{1}{2} * 3 * 3.4^2$

=> $v = 3.4 \ m/s$

Answer:

The work done is -209.42 J.

Explanation:

F(x) = (- 20 - 3 x ) N

x = 0 to x = 6.9 m

Here, the force is variable in nature, so the work done by the variable force is given by

$W =\int F dx\\\\W =\int_{0}^{6.9}(-20- 3x dx )\\\\W= \left [ - 20 x - 1.5 x^2 \right ]_{0}^{6.9}\\\\W = - 20 (6.9 - 0) - 1.5(6.9\times 6.9 - 0)\\\\W =- 138 - 71.42\\\\W = - 209.42 J$
