A thermometer is removed from a beaker of boiling water and placed in a beaker of room temperature water. The thermometer

takes 15 seconds to reach a reading of 25°C. The same thermometer is returned to the boiling water for several minutes. It is

then placed under a tap of running water at room temperature. The thermometer takes only 10 seconds to reach a reading of

25°C

What conclusion could you make about conduction and convection based on these observations?

Conduction is a more efficient method of heat transfer

Convection is a more efficient method of heat transfer

No valid conclusion is suggested by these observations:

Conduction and convection are equally efficient methods of heat transfer

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
