The second law of thermodynamics states that the can never decrease over time.  
The total energy of a system remains constant and it does not change in ideal cases.
From the statements given in the question, the correct answer is the first statement.

First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature

A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water
masya89 [10]

Answer:

option C

Explanation:

The correct answer is option C

When the ray of light pass from higher refractive index to lower refractive index then the light bend  away from the normal.

when the refracted ray is parallel to the boundary of the medium, θ₂ = 90°

and the incident angle θ₁

so, the angle  θc is known as the critical angle.

At critical angle the refracted ray becomes parallel to boundary surface.

What is number 30,31 in this picture?
Maslowich
On question 30, that is a displacement- time graph (DT). On this type of graph the gradient is equal to the velocity. B has the steepest gradient, then A and finally C

Now velocity is a vector quantity so it has a direction and speed ( speed doesn't have a fixed direction.)

on the DT graph im going to assume that movement B is a positive velocity with A and C being negative. 
So by ranking these: A is the most negative, C is the least negative and B has to be the greatest as it is the only positive velocity. 

Q31, The same type of graph is present, by looking at the gradients we can rank the largest and smallest velocities- speeds in the case of the question. 
i'll skip my working out as its the same as before:

C, B, A and then D

the same idea as on Q30 applies to Q31 part b, 

D,C,B then A

The Chartered Institute of Management Accountants defines activity-based cost management as follows: "An approach to the costing
egoroff_w [7]

Answer:

ABC is the activity based accounting. It is the costing done for each separate activity which maybe unit level, batch level, product sustaining or facility sustaining.

Explanation:

The basic difference between ABC and traditional costing systems can be explained with the help of the following diagram.

Traditional Costing System

Overhead Cost Accounts (For each individual expense e.g. tax)

First Stage Allocation

  1. Cost Centers ( normally Departments)
  2. Cost Centers ( normally Departments)

N.  Cost Centers ( normally Departments)

Second Stage Allocation ( Direct Labor Or Machine Hours)

Cost Objects ( products, services and customers)

ACTIVITY BASED COSTING SYSTEMS

Overhead Cost Accounts (For each individual expense e.g. tax)

First Stage Allocation ( resource cost drivers)

  1. Activity Cost Centers
  2. Activity Cost Centers

N. Activity  Cost Centers

Second Stage Allocation ( activity cost drivers)

Cost Objects ( products, services and customers) (Direct Costs)

Four steps are involved in the design of ABC systems.

  1. identifying the major activities that take place in an organization
  2. assigning cost to cost pools / cost centers for each activity
  3. determining the cost for each major activity
  4. assigning the cost of activities to products according to the product's demand for activities.

The first two steps relate to the first stage and final two steps to the second stage of the two - stage allocation process shown above.
