Examples of sonic boom in the following topics:
-
- A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound.
- It can be viewed as a Doppler effect on steroids; sonic booms generate an enormous amount of energy, and sound like explosions.
- The 'crack' of the whip is a result of this sonic boom.
- A sonic boom produced by an aircraft moving at M=2.92, calculated from the cone angle of 20 degrees.
- Identify conditions that lead to a sonic boom and discuss its properties
-
- The end of World War II in 1945 brought a baby boom to many countries, especially Western ones.
- There are many factors that contributed to the baby boom.
- The baby boom triggered booms in housing, consumption, and the labor force.
- An estimated 77.3 million Americans were born during this demographic boom in births.
- Describe the optimism of the baby boom era following World War II.
-
- On the other hand, the breaking of these regularities in the sonic environment can signal danger, or at the very least the need for heightened attention to be applied to the sonic "culprit."
- Identifying irregularities in the sonic environment and boosting attention and adrenaline when one is found have been absolutely essential to the survival of the human species.
-
- Solid tissues are first broken down mechanically using either a blender (for larger sample volumes), a homogenizer (smaller volumes), or by sonication .
-
- After cell lysis, the DNA is fragmented by sonication.
-
- The Market Revolution produced an upsurge in speculative investments, which resulted in periods of economic boom and bust.
- These speculative investments were frequently made with borrowed funds, resulting in large-scale cycles of boom and bust in the early 1800s.
- Cotton, at first a small-scale crop in the South, boomed following Eli Whitney's invention of the cotton gin in 1793.
-
- In vertebrates, sonic hedgehog (Shh) and Wnt morphogenetic signaling gradients establish the dorsoventral axis of the central nervous system during neural tube axial patterning.
-
- Similarly, the budget deficit tends to decrease during booms, which pulls back on aggregate demand.
- Because more people are earning wages during booms, the government can collect more taxes.
- Also, because fewer individuals need social services support during a boom, government spending also decreases.
- During boom times when the economy is doing well, people earn more income and this translates to higher tax revenues for the government, lowering the budget deficit.
-
- Sonic hedgehog (Shh) is a key player in patterning the ventral axis, while Bone morphogenic proteins (Bmp) and Wnt family members play an important role in patterning the dorsal axis.
-
- The post-World War II period in the United States witnessed unprecedented economic prosperity and important social developments, including critical shifts on the labor market, rise of mass consumerism, "baby boom," and the rapid growth of civil rights movement.
- Consumerism represented one of the consequences (as well as one of the key ingredients) of the postwar economic boom.
- As
economic prosperity empowered couples who had postponed marriage and
parenthood, the birth rate started shooting up in 1941, paused in 1944-45 (with
12 million men in service), and then continued to soar until reaching a peak in
the late 1950s (the post-war "baby boom").
- The older generation of Americans did not benefit as much from the postwar economic boom especially as many had never recovered financially from the loss of their savings during the Great Depression.
- The red segment from 1946 to 1964 is the postwar baby boom, with birth rates starting to drop around 1960.
