Answer:
The three methods of heat transfer are conduction, convection, and radiation.
Conduction is heat transfer in solids or through direct contact. Convection is heat transfer through the movement of a liquid or gas. Radiation is heat transfer through thermal emission.
Answer:
B
Step-by-step explanation:
Let's eliminate the incorrect answers. C and D are incorrect, since anything to the power of 0 is equal to 1. A is incorrect, because -1 * -1 = 1 since the negatives cancel out. B is correct, because -1*-1*-1*-1*-1 has an odd number of negatives, and thus you are left with -1 instead of 1. Therefore, the answer is B.
25.00-1.29= 23.71
23.71/4.99= 4.75
He can get 4 packs of cards
He uses sin(x):
sinx = opposite side/hypotenuse = y/ (distance eath-sun)
Since x is known and y is known, then:
Distance earth-sun = y/sinx
