There is a trend in the United States toward using coal-fired power plants to generate electricity rather than building new nuclear fission power plants. Is the use of coal-fired power plants without risk? Make a list of the risks to society from the use of each type of power plant. With this knowledge, which type of radioactive decay has the net effect of changing a neutron into a proton? Which type of decay has the net effect of turning a proton into a neutron?
A helicopter is in a steady vertical climb when it suddenly experiences a strong horizontal gust. Consider the conditions on the advancing and retreating sides of the disc and draw relevant blade element velocity
Indium antimonide (InSb) is a semiconductor with a narrow band gap of 0.17eV and an intrinsic carrier concentration of 2×1016cm-3. The mobility of electrons in InSb is 78000 cm2/V⋅s and their effective mass is 0.014m0, while the holes have a mobility..
