The best example of heat transfer by convection is when

1 answer:

6 0

A). Heat travels from the sun to the soil by radiation.

B). A ceiling fan moving air around doesn't say anything about heat.

C). It's not <em>heat</em> rising from a chimney. It's heated air.
Whenever you see a heated substance rising through some of
the same substance that's cooler, you're seeing convection.

Light bending at a boundary is caused by differences in the speed of light in different materials. The greater the difference in

olasank [31]

Answer:

How much does light bend? When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.

Which observation would be evidence that heat was transferred by radiation

Masteriza [31]

Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.

Suppose that the net resistance comes from two resistors in series: R=R1+R2. Assume that you measure each resistor independently

rewona [7]

Answer:

± (.021 ) ohm

Explanation:

In the addition of two physical quantities , the uncertainties are simply added .

So , net uncertainty in the value of R will be

± (.007 +.014)

=± (.021 ) ohm
