the answer is curie
curie- a unit of radiation equal 3.7x10^10 disintegratons persecond
Humans might build drainage systems.
Humans might extract more water from the ground.
Human behavior does not change because of the water cycle.
Answer: Humans might extract more water from the ground.
Explanation:
Humans may face the situations of unavailability of water supply. Majority of the human population is dependent upon the source of water like oceans, lakes, rivers, ponds and wells for their water supply.
But in the scarcity of water from the drainage supply by the water body human population should search for a relevant alternative such as groundwater. Groundwater is the underground reservoir of water. The water in the groundwater reservoir accumulates from the sources such as rainfall, snow melting, river and oceanic water.
Humans should search for groundwater reservoir for compensating the scarcity of water.

Chemical Energy
Answer: Mechanical Energy
Explanation:
According of law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.
When electric sharpener works by using electrical energy, it is being used to drive the blades of the sharpener and is being converted to mechanical energy which is then converted to heat energy and the sharpener gets warm.
Electrical energy is the energy possessed by virtue of motion of electrons.
Mechanical energy is the energy possessed by a body by virtue of its position and motion.
Heat energy is the transfer of thermal energy from hotter body to colder body.
47 mL
47.2 mL
47.25 mL
Answer:
47 mL
Explanation:
By the image, the beaker graduation will from 45 from 50 mL, passing by 5 markings. So each mark has 1 mL. To read the volume, we have see the meniscus, which is the concave superficie of the liquid. The meniscus is above the second mark, so it passed 2 mL from the 45 line, the volume is 47 mL.
