Abi-convex (converging) lens can produce a. only real images b. only virtual images c. both real and virtual images, depending on the object distance d. only images of objects at infinity e. only images of objects close to the lens

Option (c)

Explanation:

Convex lens forms both types of images.

When the object placed between focus and optical centre of the lens, the image formed is virtual.

When the object placed beyond focus then the image formed is real.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

given values:

mass = 0.3 kg.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
