Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of 4.

Kay [80]

Answer:

a) 1.268×10⁻⁷ cm/sec

b) 40 km/million years.

Explanation:

Speed of tectonic plate = 4.0 cm/year

a) Convert the year to seconds

1 year = 365 days × 24 hours × 60 minutes × 60 seconds

⇒1 year = 31536000 seconds

So,

$4\ cm/year = \frac{4}{31536000}\\\Rightarrow 4\ cm/year = \frac{1}{7884000}\\\Rightarrow 4\ cm/year = 1.268\times 10^{-7} cm/sec$

Distance plate will move in 1 second is 1.268×10⁻⁷ cm/sec

b) Convert cm to km

$4\ cm=\frac{4}{10^{-5}}\ km$

So, in 1 year it will move 0.00004 km

Hence in 1 million years is will move

0.00004 × 10⁶ = 40 km/million years.

Speed in kilometers per million years is 40 km/million years.

Coherent, monochromatic light is incident on a pair of slits that are 0.3 mm apart. When light passes through the slits and stri

Answer:

550 nm

Explanation:

The formula for the double-slit diffraction experiment is:

$y=\frac{m\lambda D}{d}$

where

y is the distance of the m-th maximum from the central fringe

$\lambda$ is the wavelength of the light used

D is the distance of the screen from the slits

d is the separation between the slits

In this problem we have:

$d=0.3 mm = 0.3\cdot 10^{-3} m$ is the distance between the slits

$D=1.5 m$ is the distance of the screen

We also know that the distance between the 3rd and 5th order maximum is 5.5 mm, which means that:

$y_5-y_3 = 5.5 mm = 5.5\cdot 10^{-3} m$

And we can rewrite this as:

$y_5-y_3 = \frac{5\lambda D}{d}-\frac{3\lambda D}{d}=\frac{2\lambda D}{d}$

where we used respectively m=3 and m=5. If we know solve for $\lambda$ , we find the wavelength:

$\lambda = \frac{(y_5-y_3) d}{2 D}=\frac{(5.5\cdot 10^{-3})(0.3\cdot 10^{-3})}{2(1.5)}=5.5 \cdot 10^{-7} m=550 nm$
