Scientists can determine the age of the seafloor by watching the constant changing magnetic field of our planet. When it cools down, it records the magnetic field during its formation. The two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge. Hope that helps!

Digital Communications has provided benefits to relationships especially long distance relationships. It helps people feel connected with each other. Through the use of digital communications such as Facetime or Zoom, it gives oppurtunity to people whom you feel close to interact with you through the screen. long distance relationships tends to work because of digital communications , interacting online has been a lot more easier.
Sorry if its short but i couldnt think of anything feel free to add more things if you’d like
Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
True i do believe but im not 100% sure this isnt my strong suite
