Answer:
Vertical component of velocity is 9.29 m/s
Explanation:
Given that,
Velocity of projection of a projectile, v = 22 m/s
It is fired at an angle of 22°
The horizontal component of velocity is v cosθ
The vertical component of velocity is v sinθ
So, vertical component is given by :



Hence, the vertical component of the velocity is 9.29 m/s

Answer:
The value is 
Explanation:
From the question we are told that
The the peak wavelength is 
Generally according to the Wien's displacement law
Here T is the approximate surface temperature of this star in K so
=> 
Converting to Fahrenheit ,
![T = [400 - 273.15 ] * \frac{9}{5} + 32](https://tex.z-dn.net/?f=T%20%3D%20%5B400%20-%20273.15%20%5D%20%2A%20%5Cfrac%7B9%7D%7B5%7D%20%2B%2032)
=> 
About 9.81 m/s^2
