What is the basic principle behind how sonar works?
Answer:
Sonar is based on the principle of reflection of Ultrasonic Sound waves. Ultrasonic sound waves are high frequency waves with frequency over 20Khz. The SONAR transmitter in the Ship sends the ultrasonic sound waves towards the sea bed from where they get reflected
Explanation:
Answer:
a pulse of ultrasonic waves is sent into the water where it bounces off a target and comes back to the source (ultrasonic waves are pitched too high for humans to detect). The distance and location can be calculated by measuring the time it takes for the sound to return. By knowing the speed of sound in water, the distance is computed by multiplying the time it takes for the sound to return. By knowing the speed of sound in water, the distance is computed by multiplying the speed by one-half of the time travelled (for a one-way trip). This is active sonar ranging (echolocation).

It was a time of the revolutionary war that the polish people first came to prominence in America. More than 100 polish fighters joined the side of the rebels.
What did the Life of the polish people look like?When polish people fought for their own identity and homeland they were not much successful and their identity came under a harsh attack. It was the time of the 19th century that the state of the Polish people was divided into three fragments Russian, Prussian, and Astro Hungarian empires.Although they were separated physically from their lands yet there was a common fire in each polish heart to fight for his own independence and they worshipped Roman Catholics. On whatever land they settled, they always tried to build communities and protect their national integrity.They built architectures like parochial schools and more than 900 catholic churches were also found to be made by them. We can see new Polish communities settling in today's Chicago, Detroit, and New York. What above mentioned statements follow?The Polish were largely Catholics and Jewish. More than 100 Catholic churches along with cathedrals near the region of the Great Lakes and New England were made by them.There was a town, Panna Maria, in Texas which was founded by Polish settlers in 1854. According to me, they did construct some Parochial schools but education was not the top priority for them as most of the poles were engaged in factory work and were mostly craftsmen.So, here we got to know about some practices followed by Polish immigrants.

HELP ME PLEASE!!!!!!!!!!!!!!!!!!!! The measure of an angle is 49.2°. What is the measure of its complementary angle?
Answer:
the complementary angle of 49.2° is 40.8⁰
Explanation:
Given;
measure of the angle = 49.2°
Let the complementary angle be x
Complementary angles sum up to 90 degrees.
The value of x is calculated as follows;
x + 49.2° = 90⁰
x = 90⁰ - 49.2°
x = 40.8⁰
Therefore, the complementary angle of 49.2° is 40.8⁰.

Answer:
The correct answer is - 6 square feet.
Explanation:
The area of a parallelogram is the product of its base and the height or perpendicular distance between the base and its parallel side.
Area = Base*height
Given:
length of base DC = 8 feet
the perpendicular distance between AB and DC = 3/4 feet
Solution:
By the formula,
Area = Base*height
Area = 8*3/4 = 6
Thus, the correct answer is - 6 feet.
