"These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean watergets very cold, forming sea ice." this is what I found...

On a smooth horizontal floor, an object slides into a spring which is attached to another mass that is initially stationary. Whe

HACTEHA [7]

Answer:

E) momentum and mechanical energy

Explanation:

In the context, an object is attached to the another mass with a spring which is initially at a rest position. Now when the spring is compressed, the two masses moves with the same speed. Now since the both the masses combines with the spring to move together they are considered as one system and in this case the momentum and the kinetic energy will be conserved.

The kinetic energy and momentum of the system after collision and the kinetic energy and momentum of the two masses before collision will be constant.

Which of these instruments is listed with the wrong type of lens that it uses?

VikaD [51]

The wrong type of lens-Microscope, concave

Explanation:

A microscope Basically uses two convex lenses to magnify an object, or specimen.

There are 2 lenses in a microscope

Object Lens:The lens that is closer to the object
Eyepiece:The lens that is closer to the eye

Both the object lens and the eyepiece, is a convex lens.
