Answer;
B. Increased levels of carbon dioxide, a greenhouse gas, leads to increased phytoplankton growth.
Explanation;
-A combination of warm water, high nutrient levels, and adequate sunlight may cause a harmful algae bloom. These blooms may damage aquatic ecosystems by blocking sunlight and depleting oxygen that other organisms need to survive.
-Algae blooms have been increasing globally, and climate change may be playing a role in the increment. For instance, during the warm summer season or when water is warmer, some harmful types of algae to grow faster than other, more benign varieties.
-Additionally, the warmer surface water also prevents water from mixing vertically, allowing algae to grow thicker and faster.
Answer: 20 m³
Explanation:
1) Data:
Tanker:
Vt = 2.5 × 10³ m³
Dt = 8 × 10³ kg / m³
Sea water:
Vs = ?
Ds = 1 × 10³ kg / m³
2) Physical principles and formulas
Buoyancy: weight of the object equals the weight of the water displaced (or pushed away) by the object.
Weight of water = Weight of tanker
weight = mass × g ..... g = acceleration due to gravity ≈ constant
density = mass / volume ⇒ mass = density × volume
3) Solution
Weight of water = Weight of tanker
Ds × Vs × g = Dt × Vt × g
1×10³ kg/m³ × Vs × g = 2.5 × 10³ m³ × 8 × 10³ kg / m³ × g
⇒ Vs = 20 × 10⁶ kg / ( 1 × 10³ kg/m³) = 20 m³
Answer: 20 m³
Explanation:
<h2>potential energy formula is 1/2 mv2(this 2 is square).</h2>
m means mass and v means velocity.
now, you can calculate
Answer:
past temperature, composition of gases in the atmosphere
Explanation:
Cylindrical cones can be drilled out from the core of glaciers to calculate past temperatures. The air bubbles in the cones can also be used to determine the composition of air in the past yars. This information provides us a means to analyze the trend of global warming and change in concentratinos of green house gases over the years.
