Answer:

Science is orderly knowledge proven by observation and experimentation of certain phenomena.

Explanation:

Science is an ordered system of structured knowledge that studies, researches and interprets natural, social and artificial phenomena. Scientific knowledge is obtained through observation and experimentation in specific areas. This knowledge is organized and classified on the basis of explanatory principles, whether theoretical or practical. From these, questions and reasoning are generated, hypotheses are formulated, scientific principles and laws are deduced, and scientific models, scientific theories and knowledge systems are constructed by means of a scientific method.

Science considers and is based on experimental observation. This type of observation is organized through methods, models and theories in order to generate new knowledge. For this, truth criteria and a research method are previously established. The application of these methods and knowledge leads to the generation of new knowledge in the form of concrete, quantitative and verifiable predictions referring to past, present and future observations.

Light passes from a material with index of refraction 1.25 to one with index of refraction 1.72. The angle of incidence is 34.3°

kicyunya [14]

Answer:

angle of refraction is 24.17°

Explanation:

given data

index of refraction n1 = 1.25

index of refraction n2 = 1.72

angle of incidence θ1 = 34.3°

to find out

angle of refraction (θ2)

solution

we will apply here snells law that is

n1 sinθ1 = n2 sinθ2 .........................1

here put all these value and find θ2

1.25 sin34.3 = 1.72 sinθ2

sinθ2 = 0.70440 /1.72

sinθ2 = 0.4095

θ2 = 24.17°

so here angle of refraction is 24.17°

Andrew shakes a rope, and the rope makes a wave as shown.

weeeeeb [17]

Answer: Option C. Is the correct answer.

Explanation: Wave length is the distance between the crest of each wave. If you were to decrease it you would be decreasing the distance between each wave therefore making it smaller and closer together as option C. shows.

A 1.50-m string of weight 0.0125 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Ignore the ve

Natalka [10]

Answer:

Explanation:

mass of string = .0125 / 9.8

= 1.275 x 10⁻³ kg

Length of string l = 1.5 m .

m = mass per unit length

= ( .1.275 / 1.5) x 10⁻³ kg/m

m = .85 x 10⁻³ kg/m

wave equation: y(x,t) = (8.50 mm)cos(172 rad/m x − 4830 rad/s t)

compare with equation of wave

y(x,t) = Acos(K x − ω t)

ω ( angular velocity ) = 4830 rad/s

k = 172 rad/m

Velocity = ω / k

= 4830/172 m /s

= 28.08 m /s

velocity of wave = $\sqrt{\frac{W}{m } }$

28.08 = $\sqrt{\frac{W}{.85\times10^{-3} } }$

788.48 = W / .85 X 10⁻³

W = 670 x 10⁻³ N .

c ) wave length

wave length =2π / k

= 2 x 3.14 / 172

= .0365 m

no of wave lengths over whole length of string

= 1.5 / .0365

= 41

d )

equation for waves traveling down the string

= (8.50 mm)cos(172 rad/m x + 4830 rad/s t)
