Answer: Virtual, upright and diminished.
Explanation:
A transparent material that focuses or diverges light is known as a lens. There are mainly two types of lens: concave lens and convex lens. Other lens can be made using combination of these two and plane one.
A concave lens is a diverging lens. It means the light from any real object after passing through this lens appears to diverge from the focus. A image formed by a diverging lens is virtual, upright and diminished.
Answer:
38.8 m/s
Explanation:
Force F(x) = 6 - 2x + 6x²
work
W = mv²/2=7v²/2 = 3.5v² = 5261
v = 38.8 m/s
