Answer:
Velocity = distance / time
V = 10/1
V = 10km/h
We can answer this problem by dimensional analysis. As we can see, the units of the electric field strength is newtons per coulomb. If we multiply a value with units of coulomb we will obtain newtons which is a units of force.
Force = 9.4x10^7 N / C (8.1 x10^-9 C)
Force = 0.7614 N
Hello there!
The formula for sodium sulfide is Na2S.
Hope this helps!
Answer: The alveolar process of the maxillae holds the upper teeth, and is referred to as the maxillary arch. Each maxilla attaches laterally to the zygomatic bones (cheek bones).
Explanation: wiki
Relative density is defined as:
dr = ds / dw
where:
dr: relative density
ds: density of the substance.
dw: density of water.
In this case we have the relative density of oak wood:
dr = 0.64.
We want to find the density of the substance: ds
Therefore we need to know the density of water in the cgs unit system:
dw = 1g / c ^ 3
Finally:
ds = dr * dw
ds = 0.64 * 1 g / cm ^ 3
ds = 0.64 g / c ^ 3
The density of the oak wood in cgs is 0.64 g / cm ^ 3
