Answer:

Magnetometer

Explanation:

Magnetometer technique is not using by scientists for studying the ocean floor.The scientists currently is using SONAR ( sound navigation and ragging) technique for studying the ocean floor.SONAR is used sound waves sound waves for studying the ocean floor or we can say that SONAR is based on sound propagation.

Therefore answer is Magnetometer

We can solve this problem using the law of conservation of energy.
This law states that energy in a closed system must stay same.
That means that the energy of a ball leaving the hand and the energy of a ball when it reaches its maximum height must be the same.
The energy of a ball leaving the players hand is kinetic energy:
E_k=\frac{mv^2}{2}
The energy when the ball reaches its maximum height ( and has zero velocity) is potential energy in a gravitational field:
E_p=mgh
As said before these energies must be the same, and that allows us to find the initial speed:
E_k=E_p\\
\frac{mv^2}{2}=mgh\\
v^2=2gh\\
v=\sqrt{2gh}
When we plug in all the number we get that v=14\frac{m}{s}

As per conditions described here we know that all force arrow are not of equal length

So all forces are not same in magnitude

Here applied force on right direction is more in magnitude then the friction force on left

So it will have net unbalanced force towards right due to which it will move towards right direction or in the direction of net unbalanced force

While in the upward and downward direction the forces are balanced and hence the box will not move in that direction

So normal force will be balanced by gravitational force

So here answer will be

The forces acting on the box are <u>UNBALANCED</u> .

The box will move to the <u>RIGHT</u> .
