Hitman42 [59]2 years ago
4 0

Answer:

x(t) = t^2 - 2 t + 1       given

v = dx / dt = 2 t - 2 = 0

t = 1  

It comes to rest after 1 second

Infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on Earth
liberstina [14]

Answer:

λ = 1.86 x 10⁻⁴ m = 186 μm

Explanation:

The relationship between the wavelength and the frequency of a wave is given by the following equation:

c = f\lambda\\\\\lambda = \frac{c}{f}

where,

λ = wavelength of infrared radiation = ?

c = speed of infrared radiation = speed of light = 3 x 10⁸ m/s

f = frequency of infrared radiation = 1.61 THz = 1.61 x 10¹² Hz

Therefore,

\lambda = \frac{3\ x\ 10^8\ m/s}{1.61\ x\ 10^{12}\ Hz}

<u>λ = 1.86 x 10⁻⁴ m = 186 μm</u>

gladu [14]

If you fly a spaceship to Vega at 0.999c, you will measure the distance to be much less than 25 light years.

Most space objects use light-years to represent their distance. Light-years are the distance that light travels during the year on Earth. Light-years are about 6 trillion miles (9 trillion km). This is a 6 followed by 12 zeros.

At the same speed, a movement equivalent to one light-year takes about 11.3 billion days. Life expectancy for Americans is currently estimated at 78.74 years, which is equivalent to 28,740 days. Therefore, to get there, you need to live about 400,000 times as long as the average American.

In a double-slit experiment, it is observed that the distance between adjacent maxima on a remote screen is 1.0 cm. What happens
kobusy [5.1K]

Answer:

C) It increases to 2.0 cm

Explanation:

In a double-slit diffraction experiment, the distance on the screen between two adjacent maxima is given by

\Delta y = \frac{\lambda D}{d}

where

\lambda is the wavelength of the wave

D is the distance of the screen from the slits

d is the separation between the slits

In this problem, the initial distance between adjacent maxima is 1.0 cm. Later, the slit separation is cut in a half, which means that the new slit separation is

d'=\frac{d}{2}

Substituting into the equation, we find that the new separation between the maxima is

\Delta y' = \frac{\lambda D}{d/2}=2(\frac{\lambda D}{d})=2\Delta y

So, the distance increases by a factor 2: therefore, the new separation between the maxima will be 2.0 cm.

Why is it that the number of hours in the day never change yet some days fly by and others drag on??
Serhud [2]

because the season change if you are in summer the days seem longer because the sun stays up longer if you are in the winter the days seem shorter because the sun goes down sooner.
