Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.
<span>The addition and subtraction of negatively charged electrons can easily change an atom’s charge, because they perpetually spin in valence shells outside the nucleus. It is easier for a neighboring atom to share or steal an electron rather than a positively charged proton, which is found in the nucleus. It requires a strong energy input to split a proton free from other protons and neutrons. thus, the atoms lose or gain electrons from neighboring ones and become what is known as "ions". Hope it helped!</span>
Top: The grasshopper population would begin to have a dramatic increase because of the lack of being eaten if the frogs disappeared and the snakes would decrease in population because of less food availability.
Bottom: All of the organisms in the food chain are equally as important because a drastic change would occur if one disruption was made.
C) Extensive Property
An extensive property is a property that depends on the amount of matter in a sample. The mass of an object is a measure of the amount of matter that an object contains.
Answer: The density of kerosene is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g
Volume of kersone = 
Putting in the values we get:
Thus the density of kerosene is
