1. How does the speaker describe the Birds of Paradise?​

Answer:

There are two methods of keeping departmental accounts:

1)Independent Basis: In this method, accounts of each department are maintained separately. Each department prepares Trading and Profit and Loss Account. ...

2)Columnar Basis: ADVERTISEMENTS: In this method, there is a single set of books.

Answer:

There are two methods for departmental Accounting:

METHOD 1: WHEN SEPARATE SET OF BOOKS ARE KEPT FOR EACH DEPARTMENT

As per this method, each department is taken as an independent unit and it makes its own books of the accounts.  This method is featured as:

• Separate books from other departments are maintained.
• This method is suitable for large organizations.

• The trading results are deposited with the main accountant to make the account of the whole company.

• This method is very expensive.
• It is very less common among the departmental enterprises.

METHOD 2: WHEN SEPARATE SET OF BOOKS ARE NOT MAINTAINED

As per this method, no separate records of each department is maintained, rather joint accounts are maintained of all departments. This method is featured as:

• No separate books are maintained.

• This method is suitable for small organizations.

• The whole accounts are kept by central accounts department.

• The central Accounts department maintain analytical or Columnar sales book, purchases books are maintained.

• The columnar trading accounts is maintained to calculate the gross profit and to keeping the records to stock.

• The indirect expenses are apportioned among the departments on sound basis.

• The columnar profit and loss account is maintained to calculate net profit of each department.

• The departments kept some records of sales, purchases or direct expenses at their own but not on double entry system.

• This method is less expensive.

Answer:

First of all the Sun rays fall on the Solar Collector, which is consisted a black absorbing surface (absorber) that absorbs solar radiation, and transfers the heat energy to water flowing through it. After this, heated water is collected in a tank, insulated to prevent heat loss.

DISADVANTAGES

Maintenance is one disadvantage, although most systems don’t require a high degree of care. However, scaling occurs when there are minerals suspended in domestic water, which build up as calcium deposits in the system. Adding water softeners or mild acidic substances such as vinegar can avoid scaling. It only must be done every three to five years, but this can vary depending on the water quality.

Corrosion is another concern. In open loop hydronic solar systems, oxygen can rust any iron or steel part. The plumbing components are more resistant if they’re made of copper, brass, bronze, stainless steel, plastic or rubber. Storage tanks should be lined with glass or plastic to resist corrosion as well.

Also, active systems can overheat if the size of the storage tank isn’t appropriate for the collector. The general rule is that for each square foot of collector, there should be 1.5 gallons of storage. With that in mind, such a disadvantage can be avoided.

ADVANTAGES

Advantages of Solar Water Heaters

The advantages go beyond cost savings and the availability of power, which are also realized with solar electric systems. Here are a few unique perks of home solar water heating products that may convince you to upgrade your home.

Step-by-step explanation:

speed of Sonu= 60km/hr

A/Q, distance travelled by him in 90 seconds =

60km/3600sec×90 sec = 1.5km

Given:

The speed of Sonu is 60 km per hour.

To find:

The distance travelled by him in 90 seconds.

Solution:

To answer this question, first of all, we should know that the distance 'd' travelled by an object that is moving at a speed 's' in time 't' is given by:

[tex]d = s \times t[/tex]

Now,

proceeding to the solution, we have

Speed of the Sonu = 60 km/hr

The time that was taken by the Sonu = 90 seconds

[tex] = \frac{90}{3600} [/tex]

[tex] = \frac{1}{40} \: hours[/tex]

(as in one hour = 3600 seconds)

So,

distance travelled by Sonu in 90 seconds

[tex] =60 \times \frac{1}{40} [/tex]

[tex] = \frac{3}{2} [/tex]

[tex] = 1.5 \: km[/tex]

Hence, the distance travelled by Sonu in 90 seconds is 1.5 km.
