1. <span>c. convection
</span>2. b. When it is very cold
<u>Explanation</u>
Water like any other liquid transfer heat energy through convection.
When a pot of water is put on a stove, the water at the top gets hot primarily by <span>convection.

A supperconductor is a material that can conduct electric current with no resistance at all.
The supperconductivity can be achieved under cooled temperatures.
Certain materials can become superconductors under what conditions? <u>When it is very cold</u>
Sometimes they are the same in physics. it depends how the question is worded but speed comes before velocity. If you take the derivative of speed you will end up with its velocity. The same goes when you take the integral of velocity.

organisms having a body derived from three embryonic cell layers (ectoderm, mesoderm, and endoderm), as in all multicellular animals except sponges and coelenterates.
Answer:
The focal length for given convex lens = 0.0714 m
Explanation:
Given data
Radius () = 12.5 cm
Radius () = 16.7 cm
Since the radius of curvature is positive so these are the convex lens.
Now focal length is given by
⇒ = +
⇒ Put the values of and in the above formula we get,
⇒ = +
⇒ = 0.13988
⇒ f =
⇒ f = 7.14 cm
⇒ f = 0.0714 m
Thus the focal length for given convex lens = 0.0714 m
