4.01 kg in grams :
4.01 x 1000 = 4010 g
Density = mass / volume
7.86 = 4010 / volume
Volume = 4010 / 7.86
Volume = 510.17 cm³
hope this helps!
Answer:
Many countries are undergoing an increase in technology and standard of living.
Explanation:
Answer:
A. It has a partial negative charge on oxygen and a partial positive charge on hydrogen.
Explanation:
There is an electronegativity difference between O and H atoms. The electronegativity value of O and H are 3.5 and 2.1 respectively. So the electronegativity different of the O-H bond is 3.5- 2.1 = 1.4 thus making the O-H bond polar. O being the more electronegative bond acquires a partial negative charge and H acquires a partial positive charge.
Compressions are regions of high pressure due to particles being close together
rarefactions are regions of low pressure due to particles being spread further apart
Longitudinal waves are often demonstrated by pushing and pulling a stretched slinky spring
I believe that this would be true
