Answer:
sound
Explanation:
Kinetic energy = 1/2 m v^2
KE requires movement
Answer:
- Turbidity affects the growth rate of algae (micro-aquatic plants) and other aquatic plants in streams and lakes because increased turbidity causes a decrease in the amount of light for photosynthesis.
- Turbidity can also increase water temperature because suspended particles absorb more heat.
High levels of turbidity can affect aquatic life in several ways.
- Too much turbidity might make it difficult for plants to complete photosynthesis, which in turn affects the amount of dissolved oxygen.
- Fish cannot see well in turbid water making finding food difficult.
- High turbidity reduces the penetration of sunlight into water and can limit photosynthesis and hence the growth of aquatic plants.
Explanation:
Turbidity is the measure of relative clarity of a liquid. The higher the intensity of scattered light, the higher the turbidity. Material that causes water to be turbid include clay, silt, very tiny inorganic and organic matter, algae, dissolved colored organic compounds, and plankton and other microscopic organisms
Answer:
I think it is Iron (III) sulfide
Explanation:
Answer:
<h3>The answer is 0.000002 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.000002 moles</h3>
Hope this helps you
Answer:
ΔU = -6.2 × 10⁴ J
Explanation:
The system absorbs 965 J of heat, that is, q = 965 J.
The work (w) can be calculated using the following expression.
w = -P . ΔV
where,
P is the external pressure
ΔV is the change in the volume
w = - (1.90 × 10⁵ N/m²) × (0.51 m³ - 0.18 m³) = -6.3 × 10⁴ J
The change in the internal energy (ΔU) is:
ΔU = q + w = 965 J + (-6.3 × 10⁴ J) = -6.2 × 10⁴ J
