of 5. For the circuit diagram in Figure 3.40: a) What is the effective resistance of the two 4 resistors in parallel? ge b) What is the total resistance of the circuit? c) Work out the current I. 6 V 4 1Ω 4 Ω Figure 3.40​

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

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.

because if the tool that you are using is not balanced it there would be false mass.
