Answer:
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water.

Answer:
2780 meters
Explanation:
First, convert km/hr to m/s.
87.1 km/hr × (1000 m / km) × (1 hr / 3600 s) = 24.2 m/s
160.0 km/hr × (1000 m / km) × (1 hr / 3600 s) = 44.4 m/s
Given:
v₀ = 24.2 m/s
v = 44.4 m/s
a = 0.250 m/s²
Find: x
v² = v₀² + 2a (x − x₀)
(44.4 m/s)² = (24.2 m/s)² + 2(0.250 m/s²) (x − 0 m)
x = 2780 m
The image is virtual and larger than the object.
The image is virtual and smaller than the object.
The image is real and larger than the object.
Answer:
The image is virtual and smaller than the object.
Explanation:
A concave lens is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its center than at its edges.
It always produces virtual images because the image appears to form on the same side of the lens where the object is placed.
The image is always smaller than the object. Far the object, smaller will be its image.
A light ray diagram of a concave lens is attached for a better understanding.
