Conduction
burning yourself by touching boiling water
cooking popcorn in a microwave
grabbing a warm coffee mug to warm your hands
putting ice on an injury

radiation
warm air rising off the pavement
the handle of the pot got to hot while the pot was on the stove
warm water raising to the top of the ocean and cooler water sinking

convection
heat from fire warming your hands
heat from the sun hitting a solar panel
an oven that cooks by cycling warm air from the threw the bottom out the top

is this right?

The conduction, convection and radiation are the three different mode of heat transfer and hence each cases can be arranged accordingly.

Conduction is the mode of heat transfer that occurs through the direct contact between the solid.

Convection is the transfer of thermal energy, occurs by the interaction of liquid or gas.

Radiation is that mode of heat transfer that occurs through the emissions of thermal energy.

As per the above concepts, the suitable changes are:

Conduction:

Burning yourself by touching boiling waterWarm water rising to the top of the ocean and cooler water sinking.Grabbing a warm coffee mug to warm your hands putting ice on an injury.The handle of the pot got to hot while the pot was on the stove.

Convection:

Warm air rising off the pavement.Warm water rising to the top of the ocean and cooler water sinking.An over that cooks by cycling warm air from the threw the bottom out the top.

Radiation:

Cooking popcorn in a microwave.Heat from fire warming your hands.Heat from the sun hitting a solar panel.

Thus, we can conclude that the conduction, convection and radiation are the three different mode of heat transfer and hence each cases can be arranged accordingly.

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
