Answer:
The more velocity an object has the harder it is to slow it down
Explanation:
slow it down
Answer:
F=m(a) 3.111
Explanation:
So to find the acceleration you would have to reverse the problem, a=F/m
Answer:
using the lens formula: 1/f = 1/u + 1/v
focal length f = -30 (negative because it is concave lens)
object distance u = 60
image distance v= unknown
1/-30 = 1/60 + 1/v
v = -20
So, the image is 20cm from lens (on the same side along with the object), and it is virtual (because of negative sign) and erect (concave lens must produce erect images).
#3). The wavelengths of the four types of electromagnetic
radiation on that list line up like this:
Longest ... microwaves
next . . . . . infrared waves
next . . . . . visible light waves
shortest ... ultraviolet waves
#4). The word "visible" means "able to be seen". Infrared
light and ultraviolet light are not visible to human eyes.
