The speed of Sammy, given that he expends 1750 J while jogging is 7.1 m/s

<h3>Data obtained from the question</h3>

Mass (m) = 69.5 Kg
Energy (E) = 1750 J
Speed (v) =?

<h3>How to determine the speed</h3>

The speed of Samnmy can be obtained as illustrated below:

E = ½mv²

1750 = ½ × 69.5 × v²

1750 = 34.75 × v²

Divide both side by 34.75

v² = 1750 / 34.75

Take the square root of both side

v = √(1750 / 34.75)

v = 7.1 m/s

Thus, Sammy is moving with a speed of 7.1 m/s

A laser beam of wavelength 600 nm is incident on two slits that are separated by 0.02 mm. What is the separation between adjacen

Liula [17]

Answer:

option D

Explanation:

given,

wavelength = 600 nm

width of separation = 0.02 mm

L = 5 m

for mth order maxima

$d \times \dfrac{y_m}{L}=m\lambda$

for (m+1)th order maxima

$d \times \dfrac{y_{m+1}}{L}=(m+1)\lambda$

now,

$y_m=\dfrac{mL\lambda}{d}$ and

$y_{m+1}=\dfrac{(m+1)L\lambda}{d}$

hence,

$\Delta y = y_{m+1} - y_m$

$\Delta y =\dfrac{L\lambda}{d}$

$\Delta y =\dfrac{5 \times 600 \times 10^{-9}}{0.02 \times 10^{-3}}$

$\Delta y =0.15\ m$

$\Delta y =15\ cm$

hence, the correct answer is option D
