What is the difference between dry and drag force

1 answer:

8 0

There is a difference between dragand friction. Friction is relatively constant at different velocities whiledrag increases with speed. Forexample, when you rub your hands together at different speeds, the force of friction remains the same although the heat generated will vary.

You illuminate a slit with a width of 70.3 μm with a light of wavelength 719 nm and observe the resulting diffraction pattern on

Zielflug [23.3K]

Answer:

4.3 cm

Explanation:

We are given that

Width,d=70.3 $\mu m=70.3\times10^{-6} m$

$1\mu m=10^{-6} m$

Wavelength, $\lambda=719 nm=719\times 10^{-9} m$

$1nm=10^{-9} m$

$r=2.11 m$

We have to find the width in cm of the pattern.

The angle for the first minimum m=1

$sin\theta_{min}\approx \theta=\frac{\lambda}{d}=\frac{719\times 10^{-9}}{70.3\times 10^{-6}}=0.0102 rad$

$y=r\theta=2.11\times 0.0102=0.0215 m$

The width of the pattern= $2y=2\times 0.0215=0.043 m=0.043\times 100=4.3 cm$

How is the sun related to neuclear electromagnetic and heat energy

Varvara68 [4.7K]

<span>all life on Earth is sustained by energy from sunlight. This energy is transmitted from sun to Earth in the form of electromagnetic radiation emitted by hot gas at the sun's surface. The sun is heated by nuclear fusion taking place within its core.</span>
