The smaller cross-sectional area means that the bomb has to move less material (earth or concrete) "out of the way" as it penetrates. They can make the bomb faster to increase its kinetic energy. The only practical way to do this is to add some sort of large rocket engine that fires...
To see how this works, you need to understand the various forces at work in the air and underwater. While these environments seem very different to us, water and air are actually very similar. Both are fluids, substances with mass but no shape. On Earth, an object immersed in a fluid ...
Rammed earth home design should factor in the natural elements that will affect the warming and cooling properties of the home. Passive solar design takes into account the sun's different positions throughout the year. For example, in the winter, southern-facing windows welcome the sun, while o...
How does Earth's relationship with the sun affect our planet's climate? Sun's Cycle Alters Earth's Climate What drives the Milankovitch cycles? The amount of sunlight that reaches the outer atmosphere of our planet depends on three parameters: the tilt of Earth's axis toward the plane in...

We formulate a mathematical model of RUs, public infrastructure provider (PIP), natural resources and PIs to find out how substitutability and effort asymmetry affect the general response, governance/management, and sustainability of CNHS. The model is built on the model developed in Muneepeerakul ...
The Moon: Our natural satellite When Is the Full Moon? The Full Moon is when the Sun and the Moon are aligned on opposite sides of Earth, and approximately100% of the Moon’s face is illuminatedby the Sun (see illustration). Some Full Moons are slightly less illuminated, as seen from ...
