Argument list to start-process?

Here are the examples:

$sourceFile = "C:\my path\my.exe"

Invoke-Command -computername $computer -scriptblock {
    Param($FilePath)
    Start-Process -FilePath $FilePath
} -ArgumentList $sourceFile

Or…

$sourceFile = "C:\my path\my.exe"

Invoke-Command -computername $computer -scriptblock {
    Start-Process -FilePath $using:sourceFile
} 

Keep in mind that path and exe will need to exist on the remote systems.
