An ordinary egg can be approximated as a sphere of 5 cm in diameter. The egg is initially at a uniform temperature of 5 degree C. If we suddenly drop it into boiling water at 100 degree C. How long will it take for the center of the egg to reach 70 degree C. The convection heat transfer coefficient is 1200 W/m^2 K. Water conductivity is around 0.63 W/mK at 35-40 degree C.

A six-lane freeway (three lanes in each direction) in a scenic area has a measured free-flow speed of 55 mi/h. There are 7% SUTs and 7% TTs in the traffic stream. One upgrade is 5% and 0.5 mi long. An analyst has determined that the freeway is operating at capacity on this upgrade during the peak hour. If the peak-hour traffic volume is 3900 vehicles, what value for the peak-hour factor was used

Explanation:

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
