How much did a covered wagon cost in the 1800s? It was costly—as much as $1,000 for a family of four. That fee included a wagon at about $100. Usually four or six animals had to pull the wagon. Oxen were slower, but held up better than horses or mules. What type of animal was […]

How much force can a hydraulic press produce? In case the pressure gauge reads 1000 PSI, the 1000 pounds per square inch is applied to 10 square inches. If every square inch of the surface area applies 1000 pounds of force, the 10 square inches will exert a total of 10,000 pounds of force. What […]

How does stick flex affect your shot? The higher the flex number, the stiffer the hockey stick. Flex has a lot to do with how fast a player’s slap shot is. In the act of making a slap shot, the player will scrape the blade on the ice a few inches behind the puck. This […]

What is the main form of energy? After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. ​Kinetic energy is defined as the energy of a moving object. What is energy transferred from? Energy […]

What is the difference between horizontal and vertical bar graphs? The title of the horizontal bar graph tells about the data being represented by the graph. The vertical axis represents the data categories. The horizontal axis represents the values corresponding to each data value. When using the bar graph the width of the bars must […]

A clam’s shell […]

What causes a comet to move? Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. How do I track comets? How to See Comet […]

What is the first step in obtaining minerals? The first step in the production stage is recovering the minerals; this is the process of extracting the ore from rock using a variety of tools and machinery. The second step is processing; the recovered minerals are processed through huge crushers or mills to separate commercially valuable […]
