Explanation:
Answer: c. pesticide runoff
Explanation: A point source pollution is the pollution which is caused by the pollutants whose source of origin can be traced back and further pollution can be prevented. A non-point source pollution is the one which cannot be traced back to it's origin and hence, cannot be prevented from further pollution. Trash dumping, sludge dumping and oil spill are the examples of point source pollution. But pesticide runoff is the example of non-point source pollution. A surface runoff will wiped off the pesticides from their surface and discharge them to the water body the source of origin of these pesticides will remain undetermined.
Answer: 256.2 m/s (meters per second)
Explanation: Distance covered is 12450km and time used is 13.5hours. We first convert these values to standard units for distance (meters) and time (seconds).
12450 km = 12450 x 1000 m = 12,450,000 m
13.5hours = 13.5 x 60 x 60 = 48,600s
Average speed =
The average speed of the jet is 256.2m/s
Answer: The law of mass action suggests that the rate of a chemical reaction is directly proportional to the product of the masses of the reactants. In this, each mass is raised to a power, which is equivalent to the coefficient of that reactant in the chemical reaction.
For example- For the chemical reaction-
aA + bB → C + D
Rate of the reaction α [A]ᵃ [b]ᵇ
Rate of the reaction = k [A]ᵃ [b]ᵇ
where, k = rate constant
a+b = order of the reaction.
The circulatory system plays a crucial role in carrying the nutrients absorbed by the digestive system to different parts of the body via the bloodstream. A malfunction in the circulatory system can interrupt the transportation of these nutrients, consequently disrupting the digestive process.
The digestive and circulatory systems are interconnected in the human body. Digestive process involves breaking down food into tiny particles that can be absorbed into the bloodstream. This occurs primarily in the small intestine, where most nutrients are absorbed from the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa.
However, when the circulatory system malfunctions, it disrupts the absorption of these nutrients. The circulatory system is responsible for distributing these nutrients to the different parts of the body. If it malfunctions, nutrient distribution is affected, thereby hampering overall bodily function including the digestive process.
For instance, the circulatory system plays a crucial role in carrying the absorbed nutrients from the small intestine to different parts of the body for use. This is done via the bloodstream. Therefore, a malfunction in the circulatory system can hinder this important process and subsequently disrupt the digestive system.
