Question1 A sediment core is retrieved from the middle of the North Pacific Ocean, about 1000 kilometers (620 miles)
south of the Aleutian Islands (1/4 the way to Hawaii), and at a water depth of 5000 meters (16,400 feet). The
core contains coral reef fossils, which are only found in shallow, tropical waters.
• A) Develop a hypothesis that could explain this occurrence.
B) Develop a test for your hypothesis
.
Question 2
A) Discuss how a deposit with a coarse grain size indicates whether it was deposited by a high- or low-energy
transporting mechanism.
B) Give at least 2 examples of various transporting mechanisms that would produce such a deposit.

Awoodchuck would chuck all the wood he could chuck if a woodchuck could chuck wood.

    m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| =  √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| =  √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| =  14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s

Hey did u get the answer?
