Answer:

Option (B)

Explanation:

Sonar stands for Sound Navigation and Ranging. It is a machine that is technically designed to understand the bathymetry and the topography of the ocean floor. It helps in<u> determining what kind of landforms exist on the ocean floor.</u>

Here, in this machine, sound waves are used that propagates through the ocean water. This waves then strikes the ocean floor and are reflected back. This reflected sound takes various time at different places, to be detected by the detector. This difference in time helps them to map the surface of the ocean floor.

Thus, the correct answer is option (B).

The sensor in the torso of a crash test dummy records the magnitude and direction of the net force acting on the dummy.If the du
Sunny_sXe [5.5K]

Here in crash test the two forces are acting on the dummy in two different directions

As we know that force is a vector quantity so we need to use vector addition laws in order to find the resultant force on it.

So here two forces are given in perpendicular direction with each other so as per vector addition law we need to use Pythagoras theorem to find the resultant of two vectors

so we can say

F_{net} = \sqrt{F_1^2 + F_2^2}

here given that

F_1 = 130.0 N

F_2 = 4500.0 N

now we will plug in all data in the above equation

F_{net} = \sqrt{4500^2 + 130^}

F_{net} = 4501.9 N

so it will have net force 4501.9 N which will be reported by sensor
