Anear-sighted professor has near and far points of 13 cm and 25 cm respectively. determine what power contact lens is needed for this person to see distant objects clearly and state whether this correction requires a converging or a diverging lens. what are the near and far points for the the professor’s corrected vision (i. e. when she is wearing the contact lenses)?

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
