Answer:

Explanation:

Crystallization can also be called a chemical solid–liquid separation technique, in which the mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallization occurs in a crystallizer

Which of the following are examples of centripetal acceleration? Check all that apply.

k0ka [10]

Answer: The correct answer is option B, C and E.

Explanation:

Centripetal acceleration is defined as the acceleration win which an object moves in a curved path. Formula for this acceleration is given by the equation:

$a_c=\frac{v^2}{r}$

where,

$a_c$ = centripetal acceleration

v = linear speed of the object

r = radius of the curved path

From the given options,

Option A: As, the golf ball is not moving in a curved path. Hence, it is not an example of centripetal acceleration.

Option B: As, a car is moving in a curved path. Hence, it is an example of centripetal acceleration.

Option C: As, a person is moving in a curved path. Hence, it is an example of centripetal acceleration.

Option D: As, a car is not moving in a curved path and is moving in a straight road. Hence, it is not an example of centripetal acceleration. The car is moving with zero acceleration because the direction of the car is not changing.

Option E: As, a bicyclist is moving in a curved path which is around the lake. Hence, it is an example of centripetal acceleration.

a ball is projected upward at time t = 0.00 s from a point on a roof 70 m above the ground. The ball rises, then falls and strik

grin007 [14]

Answer: 17.68 s

Explanation:

This problem is a good example of Vertical motion, where the main equation for this situation is:

$y=y_{o}+V_{o}t-\frac{1}{2}gt^{2}$ (1)

Where:

$y=0$ is the height of the ball when it hits the ground

$y_{o}=70 m$ is the initial height of the ball

$V_{o}=82m/s$ is the initial velocity of the ball

$t$ is the time when the ball strikes the ground

$g=9.8m/s^{2}$ is the acceleration due to gravity

Having this clear, let's find $t$ from (1):

$0=70m+(82m/s)t-\frac{1}{2}(9.8m/s^{2})t^{2}$ (2)

Rewritting (2):

$-\frac{1}{2}(9.8m/s^{2})t^{2}+(82m/s)t+70m=0$ (3)

This is a quadratic equation (also called equation of the second degree) of the form $at^{2}+bt+c=0$ , which can be solved with the following formula:

$t=\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$ (4)

Where:

$a=-\frac{1}{2}(9.8m/s^{2}$

$b=82m/s$

$c=70m$

Substituting the known values:

$t=\frac{-82 \pm \sqrt{82^{2}-4(-\frac{1}{2}(9.8)(70)}}{2a}$ (5)

Solving (5) we find the positive result is:

$t=17.68 s$

Complete the following sentence: The term coherence relates to the phase relationship between two waves. the polarization state

77julia77 [94]

Answer:

the phase relationship between two waves.

Explanation:

Coherence describes all properties of the correlation between physical quantities between waves. It is an ideal property of waves that determines their interference. In a situation in which there is a correlation or phase relationship between two waves. If the properties of one of the waves can be measure directly, then, some of the properties of the other wave can be calculated.
