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

Mechanical waves move energy through a medium by vibrating particles. Mechanical waves can't move energy through a vacuum because there is no matter inside of a vacuum. The three types of mechanical waves are transverse waves, surface waves, and longitudinal waves.
Answer:
The Gravitational Force is reduced 4 times
Explanation:
The equation of Gravitational force follows:
F = (G*m1*m2)/r^2
Assume that G*m1*m2 = 1 and r = 1:
F = 1/1^2 = 1 N
Multiply the radius by 2
F = 1/2^2 = 1/4 N
So doubling the distance reduces the force 4 times.
Answer:
The average acceleration of the bearings is
Explanation:
Given that,
Height = 1.94 m
Bounced height = 1.48 m
Time interval
Velocity of the ball bearing just before hitting the steel plate
We need to calculate the velocity
Using conservation of energy
Put the value into the formula
Negative as it is directed downwards
After bounce back,
We need to calculate the velocity
Using conservation of energy
Put the value into the formula
We need to calculate the average acceleration of the bearings while they are in contact with the plate
Using formula of acceleration
Put the value into the formula
Hence,The average acceleration of the bearings is
