The answer is “Heat Conduction”
Answer:
Occurs in substances that have at least one non-metal
Explanation:
The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".
To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.
In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.
So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.
Answer:
2.7 g/cm³
Explanation:
Step 1: Calculate the mass of kerosene
The mass of the full beaker (mFB) is equal to the sum of the masses of the empty beaker (mEB) and the mass of the kerosene (mK).
mFB = mEB + mK
mK = mFB - mEB
mK = 60 g - 20 g = 40 g
Step 2: Calculate the density of kerosene
Density (ρ) is an intrinsic property of matter. It can be calculated as the quotient between the mass of kerosene and its volume.
ρ = m/V
ρ = 40 g/15 cm³ = 2.7 g/cm³
Answer: 5kg
Explanation: formula K=1/2mv^2
50=10m
