A jumble of relatively young volcanic debris, some of it located where it fell in Mount Hood’s eruptive past, some of it moved here by the colossal advance of the Newton Clark Glacier during the last ice age.
Newton Clark Moraine
As a result, the rocks making up the moraine are sharp and raw, not rounded, and the debris is largely unsorted. Giant boulders perch precariously atop loose rubble, making the moraine one of the most unstable places on the mountain.
Answer:
B. Two waves have displaced in opposite directions
Explanation:
Interference occurs when two waves meet at a point in space. When this occurs, two extreme conditions can occur:
- if the two waves are in phase (=displacement in the same direction), the amplitude of the resultant wave is equal to the sum of the amplitudes of the two waves:
A = A1 + A2
and this condition is called constructive interference
- if the two waves are in anti-phase (=displacement in opposite directions), the amplitude of the resultant wave is equal to the difference of the amplitudes of the two waves:
A = |A1 - A2|
and this condition is called destructive interference. Note that if A1=A2, the amplitude of the resultant wave is zero.
Answer:
The object will accelerate in the upward direction.
Explanation:
To know the direction in which the object will accelerate, we shall determine the net force acting on the object. This can be obtained as follow:
Upward force (Fᵤ) = 300 N
Downward force (Fₔ) = 200 N
Net force (Fₙ) =?
Fₙ = Fᵤ – Fₔ
Fₙ = 300 – 200
Fₙ = 100 N upward
Thus, the net force acting on the object is 100 N in the upward direction. This implies that the object will accelerate in the upward direction because the net force acting on the object is in the upward direction.

By the same token, any random change in a gene's DNA is likely to result in a protein that does not function normally or may not function at all. Such mutations are likely to be harmful. Harmful mutations may cause genetic disorders or cancer. ... Cancer genes can be inherited
