The ears of a rabbit can be thought of as two rectangular fins that dissipate heat. The dimensions are 0.1 cm thickness, 3 cm width, and 7 cm length. The average body temperature of a rabbit is 38°C. Assume this to be the temperature of the base of the head where the ears are located. The top of the head can be assumed to be a surface with area 42 cm², neglecting the area (including the base) of the ears. Assume an adiabatic tip condition for the ears. Also, neglect radiation. The thermal conductivity of the rabbit's skin is 3 W/m.°C. The convection coefficient and temperature of the air are 8 W/m².°c and 10°C, respectively. With this in mind, find the total heat transfer from the top of the rabbit's head including the ears. 1315 W

If it is 41 F outside what is the temperature in C? What is the temperature for K? The oven is 498K What is the temperature in C What is the temperature in F? The over is 498K what is the temperature in C? What is the temperature in F?

For the last portion, why do you divide by two?

Solve it pleas

Please do the last three questions (2, 3 and 4)! Thank you in advance!  A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center.  1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs?  2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction?  3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?)  4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did…

this is 100% correct, but please tell me how to solve this carefully.

Find the measurement that is a) most accurate and b) the most precise. 459 ft; 600 ft; 190 ft.

this is 100% correct, but please tell me how to solve this carefully.
