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).

A parallelogram is shown below: A parallelogram ABCD is shown with DC equal to 8 feet and the perpendicular distance between AB and DC equal to 3 over 4 feet. Part A: What is the area of the parallelogram? Show your work.
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.
What advantage does using a multi-beam sonar system have over using a single beam system?
Answer:
The benefits of multibeam echo sounders are that they map the seafloor by a fan of narrow acoustic beams, thus providing 100% coverage of the bottom. The resulting seabed maps are more detailed than those obtained using single-beam mapping. The maps are also produced faster, reducing your ship survey time.

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.

How does the Arctic Ocean compare to the rest of the oceans in depth?
Answer:
The Arctic Ocean may be the world's smallest, but it's becoming a critical region as climate change warms it more quickly than anywhere else on Earth.
Explanation:
The Arctic Ocean is Earth's northernmost body of water. It encircles the Arctic and flows beneath it. Most of the Arctic Ocean is covered by ice throughout the year—although that is starting to change as temperatures climb. Pale and stark on the surface, the Arctic Ocean is home to a stunning array of life. Though it's the world's smallest ocean-spanning 6.1 million square miles—the Arctic is now receiving unprecedented international attention. Scientists are racing to understand how warming temperatures will alter Arctic Ocean waters—and by extension, the rest of the climate—and world leaders are racing to control newly opening waters. The Arctic Ocean is warming faster than anywhere else on Earth and feeling the onslaught of climate change.
