Velocity = fλ

where f is frequency in Hz, and λ is wavelength in meters.

<span>2.04 * 10⁸ m/s =  5.09 * 10¹⁴  Hz   *  λ </span>

<span>(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴  Hz ) = λ </span>

<span>4.007*10⁻⁷  m =  λ </span>

<span>The wavelength of the yellow light = 4.007*10⁻⁷  m<span> </span></span>

Our power plant generates electricity using a steam turbine. At the exit from our power generation process, we end up with 562.0
stellarik [79]

Answer:

The mass flowrate of the cooling water needed to meet the regulation is 560 kg/s

Explanation:

The given information are;

The mass flow rate of the water = 562.0 kg/s

The temperature of the exit water = 330.0 K

The allowable temperature of the of released water into nearby river = 310.00 K

The temperature of the cool water with which the temperature of the exit water is cooled = 290.00 K

Therefore, we have;

Heat gained by the mixture = The heat of the final mixture exited to the river

Q = m×c×ΔT

m_w = 562.0 kg/s

The mass of the cooling water = x

The final temperature = 310 K

4.2×562×(330 - 310) = x×4.2×(310 - 290)

47208 = 84×x

x = 47208/84 = 560 kg

Therefore, the mass flowrate of the cooling water needed to meet the regulation = 560 kg/s.

A spaceship travels at a speed of 0.95c to the nearest star, Alpha Centauri, 4.3 light years (ly) away. How long does the trip t
Aleonysh [2.5K]

Answer:

A  1.4ly

Explanation:

speed v= 0.95c c= speed of light distance t₀=4.3ly

As per the time dilation priciple we know that

t=t_{0}\sqrt {\frac {c^2 -v^2}{c^2}}

\Rightarrow t=4.3\sqrt {1-0.95^2}

t=1.4 ly

therefore, it will take 1.4ly for the trip from the point of view of passenger on ship. ly here is light year.
