two masses m1 and m2 fall freely with the same height which will hit the ground first ?reason for the answer.

Rina8888 [55]

Answer:

They land at the same time.

Explanation:

Two masses falling through a vacuum (no air resistance or buoyancy forces) will accelerate at the same rate when dropped from the same height. Therefore, despite having different masses, they land at the same time.

Light of wavelength 578.0 nm is incident on a narrow slit. The diffraction pattern is viewed on a screen 62.5 cm from the slit.

yaroslaw [1]

Answer:

$80.6\mu m$

Explanation:

When light passes through a narrow slit, it produces a diffraction pattern on a distant screen, consisting of several bright fringes (constructive interference) alternated with dark fringes (destructive interference).

The formula to calculate the position of the m-th maximum in the diffraction pattern produced in the screen is:

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

where

y is the distance of the m-th maximum from the central maximum (m = 0)

$\lambda$ is the wavelength of light used

D is the distance of the screen from the slit

d is the width of the slit

In this problem, we have:

$\lambda=578.0 nm = 578\cdot 10^{-9} m$ is the wavelength

D = 62.5 cm = 0.625 m is the distance of the screen

We know that the distance between the third order maximum (m=3) and the central maximum is 1.35 cm (0.0135 m), which means that

$y_3 = 0.0135 m$

For

m = 3

Therefore, rearranging the equation for d, we find the width of the slit:

$d=\frac{m\lambda D}{y_3}=\frac{(3)(578\cdot 10^{-9})(0.625)}{0.0135}=80.3\cdot 10^{-6} m=80.6\mu m$
