B. Warm air rises and takes heat with it; eventually it cools and sinks.
Explanation:
Warm air rising and taking heat with it which eventually cools and sinks describes a typical convection current. This is not radiation
Convection and radiation are both forms of heat transfer alongside conduction.
Radiation is the only form of heat transfer that does not involve the use of a medium or particles.
Air is a medium and it flouts the concept of heat transfer by radiation.
Convection is mostly taking place in fluids especially liquid and gas.

Answer:
Here,
Initial velocity(u)=0 m/s
acceleration(a)=1.5m/s
time(t)=0.5s
Now,
distance covered(s)=ut+(1/2)at^2
=0*0.5+(1/2)*1.5*0.5*0.5
=0+(1/2)*0.375
=0+0.1875
=0.1875(nearly 0.19)
Hence,0.19 is correct answer.
<span>newton say that she must use her hand to put up the cup because the work is equal to force times it distance, that is in the same direction of the force applied. if carole used her hand to put up the cup, then he is not applying any work because the displacement is not in the same direction of the force</span>
