<h3><u>Answer;</u></h3>

<em>S waves are known as secondary wave or shear waves</em>

<h3><u>Explanation;</u></h3>
  • <em><u>Seismic wave are types of waves that result from break down of rocks within the earth or an explosion</u></em>. Seismic waves are classified as body waves and surface waves.
  • <em><u>Body waves are classified into either secondary waves or primary waves</u></em>. Commonly known as the<em><u> S-waves and the P-waves.</u></em>
  • <em><u>Secondary waves are types of body waves that move through an object's body unlike th</u></em>e case of surface waves. It is the second wave that is felt after an earthquake.

A lamp is 10% efficient.How much electrical energy must be supplied to the lamp each second if it produces 20 J of light energy
k0ka [10]

If it produces 20J of light energy in a second, then that 20J is the 10% of the supply that becomes useful output.

20 J/s = 10% of Supply

20 J/s = (0.1) x (Supply)

Divide each side by 0.1:

Supply = (20 J/s) / (0.1)

<em>Supply = 200 J/s  </em>(200 watts)

========================

Here's something to think about:  What could you do to make the lamp more efficient ?  Answer:  Use it for a heater !

If you use it for a heater, then the HEAT is the 'useful' part, and the light is the part that you really don't care about.  Suddenly ... bada-boom ... the lamp is 90% efficient !

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.

The following equation is an example of decay?<br><br> 232/90 TH---4/2 HE +228/88 RA?
DaniilM [7]

Answer:

Alpha decay

Explanation:

  • Alpha decay is one of the three major types of decays, others being, beta decay and gamma decay.
  • <em><u>When a radioactive isotope undergoes alpha decay it emits alpha particles. An alpha particle is equivalent to the nucleus of Helium atom.</u></em>
  • <em><u>Therefore, an atom undergoing decay, its atomic mass is decreased by 4 and its atomic number is decreased by 2. </u></em>
  • Thus, since 232/90 Th, has undergone alpha decay its mass number is reduced by 4 to 228 and its atomic number by 2 to 88, and becomes 228/88 Ra.
