hello by multiply both political parties by Ho. So, image elevation is object height times negative of photo distance split by thing distance. So, that's one millimeter times an adverse two centimeters divided by eight centimeters and that gives negative 0.250 millimeters. Now, the units here are a bit interesting. Often, and usually in formulas, we readjust the units right into meters, kilograms, and also seconds, MKS units. But in this case, the centimeters, you deserve to see are going come cancel, and you're going to it is in left with millimeters. So, we can just jump right to millimeters in our answer without needing to convert to meters. Currently in part C, if the object street was rather 25 centimeters and also not 8 centimeters, what would certainly the height of the photo be? So, we have actually the same information we're looking at is this one millimeter detail on the ring. And, we multiply that an unfavorable two centimeters divided by 25 centimeters, i m sorry is negative 0.0800 millimeters. And also so, hosted at 25 centimeters, the image on the retina is lot smaller and also so, there will not it is in as much observable detail, i m sorry is why we lug things closer to look at them in an ext detail due to the fact that bringing points closer boosts the dimension of the photo on the retina.">
