Answer:
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum."
Explanation:
Around every 11 years, the sun passes through a solar cycle. The cycle is defined by increasing and decreasing sunspots— noticeable on a sun's surface as dark imperfections, or photosphere.
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum." The latest solar minimum was obtained in 2008
Answer:
v = 70 m/s
Explanation:
Range on the cannon ball is given as
![d = 500.0 m](https://tex.z-dn.net/?f=d%20%3D%20500.0%20m)
here the angle of the projection of the ball is given as 45 degree
now we know that if the velocity of the ball is "v" then its two components will be given as
![v_x = vcos45](https://tex.z-dn.net/?f=v_x%20%3D%20vcos45)
![v_y = vsin45](https://tex.z-dn.net/?f=v_y%20%3D%20vsin45)
so here time of flight of the motion is given as
![T = \frac{2v_y}{g}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2v_y%7D%7Bg%7D)
![T = \frac{2vsin45}{g}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2vsin45%7D%7Bg%7D)
also the range is given as
![R = v_x T](https://tex.z-dn.net/?f=R%20%3D%20v_x%20T)
![R = (vcos45)(\frac{2vsin45}{g})](https://tex.z-dn.net/?f=R%20%3D%20%28vcos45%29%28%5Cfrac%7B2vsin45%7D%7Bg%7D%29)
now plug in all data in this equation
![500.0 = \frac{v^2(2sin45cos45)}{g}](https://tex.z-dn.net/?f=500.0%20%3D%20%5Cfrac%7Bv%5E2%282sin45cos45%29%7D%7Bg%7D)
![v = 70 m/s](https://tex.z-dn.net/?f=v%20%3D%2070%20m%2Fs)
Answer:
it is maybe A but i'm not 100% sure
Explanation:
its the only one that is mixed
I would say it’s “donating” so giving up...
