That's true. The give-away is "observation ... in the real world". That's what "field reports" are.

The part I'm not so sure about is those "entific findings".

A student is doing a lab experiment in which she uses diffraction to measure the width of a shaft of her hair. She shines a 530

professor190 [17]

Answer:

.09 mm

Explanation:

In case of diffraction by single slit with width a the width of central maxima is given below

width = 2 λD/a

where λ is wavelength of light , D is distance of screen , a is width o slit

substituting the given values

14 x 10⁻³ = $\frac{2\times530\times10^{-9}\times1.2}{a}$

a = .09 mm

b) If a is greater , width of central maxima will be less wide.

Tripling the displacement from equilibrium of an object in simple harmonic motion will bring about a change in the magnitude of

Anni [7]

Answer:

acceleration will be tripled.

Explanation:

We know, when an object is performing Simple harmonic motion, the force

experience by it is directly proportional to its displacement from its mean position.

Also, F = ma , therefore, acceleration is also proportional to its displacement .

Now, F = kx

Therefore, $a=\dfrac{k\ x}{m}$

If we triple the displacement i.e, 3x.

Acceleration $a'=\dfrac{k(3x)}{m}=3a.$

Therefore, acceleration is also tripled.

Hence, this is the required solution.
