The wavelength of the radiation emitted by the star is 183 nm.
Explanation:
As per Wien's displacement law, the product of emitted wavelength and temperature of the star will be equal to 2.898 × 10⁻³ mK.
So if the wavelength of the emitted radiation by Sun is given as 550 nm, then the temperature of the Sun will be
Then if the temperature of star is said to be 3.5 times hotter than Sun, then the temperature of Star = 3.5×5.27×10³ = 15.81×10³ K.
With this temperature, the wavelength of the emitted radiation can be found as follows:
So, the wavelength of the radiation emitted by the star is 183 nm.
All the big volcanoes are in the northern hemisphere of Mars, and most of the craters are in the southern hemisphere is of the following statements that best characterizes the surface of the planet Mars.

Answer:
306,284,275,000
Explanation:
If 209g was made by 1 cow you would multiply 209 by 4,015,000 and if you are trying to find how much was made in a year get that number and multiply it by 365.
The value of the final speed depends on the mass of the ore.
Let's call m the mass of the ore. We can solve the exercise by requiring the conservation of momentum, which must be the same before and after the ore is loaded.
Initially, there is only the cart, so the momentum is
After the ore is loaded, the new mass will be (1200 kg+m), and the new speed is
. The momentum p is conserved, so it is still 12960 kg m/s. Therefore, we have
and so the final speed is
Pass through it easily is called a Metals such as iron, steel, copper, and aluminum are good conductors.
