Explain the Methods and Techniques of Departmental Accounting.​

Answer:

The required time lapse is (4) 1.5 s.

Explanation:

Let , the first body fell 's' meters down in 't' seconds.

According to the question , the second body fell 's₀' meters in ( t - 1 ) seconds.

Both of them started falling from rest , so the initial velocity for both body is 0 m/s .

let , the acceleration due to gravity is g = 10 m/s²

then , s = 0 × t + ( 1/2)gt² ⇒ s = (1/2)gt²

and , s₀ = 0 × t + ( 1/2 )g( t - 1 )² ⇒ s₀ = ( 1/2 )g( t - 1 )²

According to the question ,

s₀ = s - 10

⇒  ( 1/2 )g( t - 1 )² =  (1/2)gt² - 10

⇒ ( 1/2 )g( t² - 2t + 1 ) = (1/2)gt² - 10

⇒ ( 1/2 )gt² - gt + g/2 = (1/2)gt² - 10

⇒  gt = 10 + g/2

⇒ 10t = 10 + 5

⇒ 10t = 15

⇒ t = 1.5 seconds

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 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.
