The answer is D. This means that is you have a determined amount of force (in newtons) being applied on an object of known mass (in kilograms), then to determine the acceleration of the object, divide the force by the mass (or multiplying the force with the inverse of the mass of the object). This behavior of objects is stipulated in Newtons/ second law. Increasing the force increases the acceleration while increasing the mass decreases the acceleration of the object. Acceleration is a vector quantity meaning it has magnitude and direction.
Answer:
Many human and physical factors affect population distribution and population density across the world. Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.
There are two things that occur in aquarium ammonia chemisty. 1. the build up of natural ammonia and nitrate in the water. 2. displacement of oxygen in the water caused by the ammonia. This is a very real threat especially when you have a new tank that is still cycling or when the biological filter has been upset or removed.
Look for these main symptoms if you suspect ammonia poisoning in your fish tank:
-loss of appetite
-lethargic fish
-fish gasping for air/breath at the top of the water
-fish laying at the bottom of the tank
-red/purple gills
-red streaking on the fish's body
- fins becoming torn and jagged
-scales on fish falling off or turning black
Answer:
b hummingbirds have the ability to hover while drinking nectar
Explanation:
because this allows for power in both the upward and downward beats of the hummingbirds wings
Answer:
pyroclastic flow is a fast moving current of hot gas and volcanic matter that flows along the ground away from a volcano at high velocities.
Hotspot is volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle
caldera-a large volcanic crater, especially one formed by a major eruption leading to the collapse of the mouth of the volcano.
tephra-rock fragments and particles ejected by a volcanic eruption
epicenter-the central point of something, typically a difficult or unpleasant situation
fault-an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a particular surface
surface waves- mechanical wave that propagates along the interface between differing media
body waves-A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves.
sorry if this doesnt help
