Nothing will change, it's still going at 9 km/h.
Hope this helps.

<h3>How did scientists “discover” Pangea and other supercontinents of the past?</h3>
Nowadays, they can study the geologic record and use radioactive dating, seismic surveys, and other technologies to construct maps of how the world looked at various points in Earth's history.
Answer:
Velocity of a proton, 
Explanation:
It is given that,
Potential difference, 
Let v is the velocity of a proton that has been accelerated by a potential difference of 15 kV.
Using the conservation of energy as :
q is the charge of proton
m is the mass of proton
or
So, the velocity of a proton is 
. Hence, this is the required solution.
<u>Answer</u>
Mean
<u>Explanation</u>
For any set of date there is a typical value for the probability distribution called central tendency.
There three types of central tendency<em> mean, median and mode.</em>
Mean is the average value of all data set in a distribution.
median is the the central value when the data is arranged in ascending or descending order.
Mode is the value that occurs most in a set of data.
Answer:
The material cost for making one ton of the brass sample that I have is $8149.04.
Explanation:
Density of copper = 8.96 g/cm^3 = 8.96×10^-3 kg/cm^3
Price of copper = $6.13/kg
Price of copper per volume = 8.96×10^-3 kg/cm^3 × $6.13/kg = $0.0549/cm^3
Density of zinc = 7.14 g/cm^3 = 7.14×10^-3 kg/cm^3
Price of zinc = $1.8/kg
Price of zinc per volume = 7.14×10^-3 kg/cm^3 × $1.8/kg = $0.0129/cm^3
Price of brass per volume = 0.0549 + 0.0129 = $0.0678/cm^3
Density of brass I have is 8.32 g/cm^3 = 8.32 g/cm^3 × 1 kg/1000 g × 1 ton/1000 kg = 8.32×10^-6 ton/cm^3
Price = $0.0678/cm^3 ÷ 8.32×10^-6 ton/cm^3 = $8149.04/ton
