The Earth rotates 365 times during each complete revolution.
HOPE THIS HELPS! ^_^
Answer:
Q = 217.63J
Explanation:
Data;
Mass = 34.5g
T1 = 26.4°C
T2 = 75.3°C
c = 0.129J/g°C
Energy (Q) = mc(T2 - T1)
Q = 34.5 * 0.129 *(75.3 - 26.4)
Q = 4.4505 * 48.9
Q = 217.629J
Q = 217.63J
The heat gained was 217.63J
A variable that is not being directly tested during an experiment should be independent
Answer:
Loss of biodiversity in the wetlands.
Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.
Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.
Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.
