well enter I own expressing off table salt ical zero point to it Multiply. Return to the power minus nine meters. Uh inter ionic. Enter ionic passing is equal. Do zero point 282 multiply by 10 to the power minus nine meters. Months off. Neutron must off. Neutron is equal to 1.674 multiplied by tend to the bar minus 27 kilograms. Well, we know that the probably that length is called toe playing constantly writing momentum solving. For Ricky, the lost T is equal toe, each divided by mass times. Ah, back Clint. Let's plug in the values, which is 6.63 Multiply by 10 to the power minus 34. Jule second, divided by must off neutron is 1.674 Multiply by 10 to the power minus 27 kilogram times. The battle in and prevalent equals zoo point ah 0.28 to multiply Returned to the power minus mine meters way is equal to ah six point 63 multiplied by 10 to the power minus 34 divided by ah zero point for uh, seven multiplied by 10 to the dollar minus 36 dividing the two numbers, velocity is equal to 14 0.4 multiplier. I turned to the power to and this can be further returning. Sze one point for multiply by 10 to the power tree meter per second since 10 to the power tree is a killer, therefore lost years ago in tow, one point for kilometer for a second.
