Answer:
As waves get closer to a beach they decrease in height.
Explanation:
As a wave crest approaches the shoreline, it is usual that one end of the line is closer to the shoreline than the other. The implication of this is that the energy in a wave is also spread over quite a larger area,this in turn reduces the height of the waves. In other words, refraction often makes waves smaller.
Waves are caused by wind. Wave height in the open ocean is determined by three factors. The greater the wind speed the larger the waves. The greater the duration of the wind (or storm) the larger the waves. The greater the fetch (area over which the wind is blowing - size of storm) the larger the waves.
Answer:
1. The number of turns on the secondary output is 18
2. The root mean square power delivered to the transformer is 48 Watts.
Explanation:
A transformer is an electronic device that can be used for increasing or decreasing the value of a given voltage. It consists of primary coils and secondary coil of a definte number of turns. When voltage flows in the primary coil, it induces voltage in the secondary coil. The two types are: step-up and step down transformers.
1. For a given transformer,
= 
where 
is the value of the induced voltage in the secondary coil, 
is he voltage in the primary coil, and 
is the number of turns of the secondary coil, 
is the number of turns in the primary coil.
From the question,
= 9.0 V, = 120 V, = 240, = ?
So that,
= 
= 
= 18
The number of turns on the secondary output is 18.
2. 
= 
× 
= 0.4 × 120
= 48 W
The rms power delivered to the transformer is 48 Watts.
B. New homes
This is because in community redevelopment programs, the focus is on rebuilding and reconstruction of damaged or unused properties.
alright stay thicc and enjoy
