Why is 30% recommended as the minimum Michelson contrast?
forsale [732]

Answer:

Explained

Explanation:

Michelson contrast is used for patterns where the distribution of bright and dark segments is nearly equal.

It is given by:

m= \frac{I_{max}-I{min}}{I_{max}+I{min} }

where I_max = maximum illumination and I_min = minimum illumination

we know that

typically, I_min = 54% of I_max  (general standard)

or I_min = 0.54 I_max

putting this value in above equation to get m

this approximately corresponds to m = 0.3 or 30%

hence, 30% recommended as the minimum Michelson contrast

Arada [10]

Answer:

Biodiversity.

A 30.0 kg child, initially at rest, slides down a 2.0 m tall slide. The child reaches the bottom of the slide with a speed of 6
HACTEHA [7]

Answer:

Explanation:

Total energy is constant

E = mgh + ½mv² + Fd

At the top of the slide, all energy is potential

E = mgh + 0 + 0

At the bottom of the slide, all potential energy has converted to kinetic and work of friction.

mgh = ½mv² + W

W = mgh - ½mv²

W = 30.0[(9.81)(2.0) - ½6²]

W = 48.6 J

A factory robot drops a 10 kg computer onto a conveyor belt running at 3.1 m/s. The materials are such that μs = 0.50 and μk = 0
frutty [35]

Answer:

x = 1.63 m

Explanation:

mass (m) = 10 kg

μk = 0.3

velocity (v) = 3.1 m/s

Assuming that most of the computers weight is applied on the belt instantaneously, we can apply the constant acceleration equation below

x = v^{2}/2a

where a = μk.g , therefore

x = v^{2}/2μk.g

x = (3.1 x 3.1)/(2 x 0.3 x 9.8)

x = 1.63 m

The type of chemical bond that involves the transfer of electrons between atoms is a(n) bond.
GaryK [48]
<h3>Answer;</h3>

<em>-Ionic bond</em>

<h3>Explanation;</h3>
  • <u>Ionic bond</u> is a type of bonds that results from transfers of electrons from one atom to another.  This types of bond is formed between metals and non metals.
  • Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion.
  • For instance; between sodium and chlorine element; sodium donates a single electron to attain a stable configuration while chlorine gains an electron to achieve stable configuration, thus forming an ionic compound sodium chloride.
