Question 10 is pretty easy, just convert 200MHz in meters using the speed of light, multiply it by 60 ("60 wavelenghts") and that's all.
If I have time I'll try to do the others later

12 is similar to 10, you have a time and need to find a distance using speed of light, since it's a radiation. Once the distance scout-helicopter is found, use trigonometry to find the height of the helicopter.
