the horizontal under the influence of a restraining force of 1064 N acting parallel to the include and up the incline. Down the plane is positive and up is negative direction. Acceleration of gravity is 9.8 m/s2.

What is the magnitude of accelaration of the block (answer in m/s)?

The resulting motion is: a) up the plane, acceleration is negative
b) down the plane, acceleration is positive
c) undetermined

Hydrogen sulfide decomposes according to the following reaction, for which Kc = 9.30 *10^-8 at 700°C.

2 H2S(g) <==> 2 H2(g) + S2(g)

If 0.48 mol H2S is placed in a 3.1 L container, what is the equilibrium concentration of H2(g) at 700°C? (answer in units of M)

My friends and I were having a conversation and the question arose (somehow), "If you were to take a 7 foot (in diameter) sphere out of the center of the Earth and put a human in there, what would the effect be?" One of my friends says gravity would tear him apart or compact him, but another says forces would cancel out. If anyone can answer this I would be greatful.

Micro-evolution is fact. It has been proven through experimentation and observation. If you don't believe in micro-evolution, please don't answer by telling me that. Only answer the question.

If you take two populations of a species, and put them in separate environments and allow micro-evolution to occur. Doesn't it make sense that given enough time, micro-evolution will create enough changes that they will become different species from each other? And this would then become Macro-evolution.

A jogger travels a route that has two parts. The first is a displacement A of 2.80 km due south, and the second involves a displacement B that points due east.
(a) The resultant displacement A + B has a magnitude of 4.56 km. What is the magnitude of B? __________ km
What is the direction of A + B relative to due south? _______degrees (east of south)
(b) Suppose that A - B had a magnitude of 4.56 km What then would be the magnitude of B and what is the direction of A - B relative to due south?
_________ km
direction of A - B relative to due south
__________ degrees (west of south)

On a safari, a team of naturalists sets out toward a research station located 5.2 km away in a direction 42 degrees north of east. After traveling in a straight line for 2.5 km, they stop and discover that they have been traveling 29 degrees north of east, because their guide misread his compass. What are the magnitude and direction (relative to due east) of the displacement vector now required to bring the team to the research station?
magnitude ________ km
direction ________ degrees (north of due east)
