Answer:

The answer is D , none of the above

Explanation:

1600÷8=200s 1200÷90=13.33s 50÷15= 3.33s (1600+1200+50)/(200+13.33+3.33) = 13.15m/s

The diagram shows organisms a diver observed during an ocean dive.
Nina [5.8K]

The diver most likely refers to the ocean's surface when describing the squid's location. Option A is correct.

<h3>What is the height?</h3>

The vertical distance between the object's top and the bottom is defined as height. It is measured in centimeters, inches, meters, and other units.

The organism is shown as;

Seaweed = - 20 meters

Clownfish  =  - 23 meters

Squid = - 44 meters.

The given data is a reference from the surface of the ocean. The negative sign in the data shows that the given height is below the ocean surface.

The diver most likely uses the ocean surface as a reference point to describe the position of the squid.

Hence, option A is correct.

To learn more about the height, refer to the link;

What would be the magnitude of the electric field 0.75 m from a 0.63 C master charge and what would be the force on a 0.50 C tes
bagirrra123 [75]

The magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.

<h3>Electric field on the master charge</h3>

E = kq/r²

where;

  • q is magnitude of master charge
  • r is distance of separation
  • k is Coulomb's constant

E = (9 x 10⁹ x 0.63)/(0.75²)

E = 1.008 x 10¹⁰ N/C

<h3>Force on the test charge</h3>

F = Eq

where;

  • E is electric field
  • q is the test charge

F = (1.008 x 10¹⁰) x (0.5)

F = 5.04 x 10⁹ N

Thus, the magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.
