Answer:
Winds are caused by differences in air pressure. Unequal heating of Earth’s surface creates areas of different pressure. Cooler areas have higher air pressure. Warmer areas have lower pressure. This causes air to move from high pressure to low pressure. This movement is the wind we feel.

Answer:
Explanation:
Let the first height be h . second height .75h
third height .75h . fourth height .75²h
fifth height .75²h , sixthth height .75³ and so on
Total distance consists of two geometric series as follows
1 ) first series
h + .75h + .75²h + .75³h......
2 ) second series
.75h +.75²h +.75³h + .75⁴h .......
Sum of first series :
first term a = h , commom ratio r = .75
sum = a / (1 - r )
= h / 1 - .75
= h / .25
4h
sum of second series :--
first term a = .75 h , commom ratio r = .75
sum = a / (1 - r )
= .75h / 1 - .75
= .75h / .25
3h
Total of both the series
= 4h + 3h
= 7h .
h = 1 m
Total distance = 7 m
Answer:
9 kW-hr
Explanation:
3000 W = 3 kW for 1 hr = <u>3 kW - hr </u>
2000 W = 2 kW for 3 hr = <u> 6 kW -hr</u>
<u />
total power = <u> 3 + 6 = 9 kW-hr</u>
With the below stated fact I think that the pros of using synthetic materials outweighs the cons.
Before we answer the question
If the pros of using synthetic materials outweigh the cons or otherwise, let us first establish the what a synthetic material is and its pros and cons
Synthetic material
Synthetic material is a material in which a substances are changed chemically to produce a material with different characteristics.
Types of Synthetic material
- Plastic bag
- Synthetic fiber/cloth
- Artificial sweetener
- Synthetic fuel
- Aspirin
Pros of Synthetic materials
- They are used in construction because of there strong bonding
- They can be molded
- They can be colored into any shade
- They are cheap
Cons of Synthetic materials
- Sometimes none degradable
- They do not absorb water.
- They are highly flammable
- Melts easily
In conclusion
Although Synthetic materials has so very pressing disadvantages to human kind it is unrefusable the importance of Synthetic materials to the day to day live of all humans
Therefore, I think that the pros of using synthetic materials outweighs the cons
