An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater. How deep is th
1 answer:
Answer:
The water below the vessel is 4590 m deep.
Explanation:
Calling <em>d</em> the distance between the vessel and the ocean floor, <em>v</em> the ultrasonic wave velocity, and <em>t</em> the time it takes for the ultrasonic wave to reach the bottom from the vessel, we get:
[1]
<em>v</em> is already provided (1530 m/s), so we need to find <em>t</em>.
We know that the delay of the echo is 6 seconds. That is the time it takes the wave to travel to the ocean floor and come back to the vessel, which is twice the time it takes to go from vessel to the floor, so:
Replacing and solving on [1], we get
Which is the distance from the vessel to the ocean floor.

Answer:
The nuclei experience a force that will move it to the right of the conductor rod while the electrons experience a force that will move it to the left side of the conductor rod.
Explanation:
The force that act on the charges(both the positive and the negative charge ) is Mathematically expressed as
F = qE => E = F/q
where F is the force, q is the charge and E is the electric field
we can see that the force is directly proportional to the electric field,so an increase in the electric field would increase the force.
we can also see that the electric field is given as force per unit charge and generally the direction of this field is taken to be the direction of the force it would exert on a positive test charge
Now from the question we are being told that the external electric field is the direction of the positive x axis
Hence this field would drive the positive charge i.e the nuclei to the right.
In order to further explain let consider this
Generally the electric field is always radially outward originating from a positive point charge and radially in toward a negative point charge.
what this means for this question, is that the positive point charge is on the left side of the electric field while the negative point charge is at the right side of the field.
According to Coulomb's law which states that unlike term attract while like terms repel, it means that the electron would move to the left of the conductor rod while the nuclei would move to the right side of the conductor rod.
