Which force is most important in tug of war? The normal force is the force with which the two surfaces are pushed together. In the case of this simple tug of war above, the ground pushes up with a force equal to the gravitational weight of the person. This means that heavier people will have […]
How much does it cost to fix hydrostatic pressure?
How much does it cost to fix hydrostatic pressure? Fixing this is between $350 and $500 per crack. Hydrostatic pressure is a different story. This is pressure that builds up underground when the water has nowhere to go. It forces itself up and through your foundation, often causing cracks. How do you know if you […]

What causes a glacier to advance?
What causes a glacier to advance? Glaciers advance and retreat. If more snow and ice are added than are lost through melting, calving, or evaporation, glaciers will advance. If less snow and ice are added than are lost, glaciers will retreat. In this zone, the glacier gains snow and ice. What is probably the least […]

How do you determine accuracy and precision?
How do you determine accuracy and precision? Accuracy is determined by how close a measurement comes to an existing value that has been measured by many, many scientists and recorded in the CRC Handbook. Precision is how close a measurement comes to another measurement. Precision is determined by a statistical method called a standard deviation. […]
What is the surface tension of ethanol?
What is the surface tension of ethanol? 415. Ethanol–Mercury. 20 °C. 389. Water–1,2-Dichloroethane. Which has more surface tension water or honey? Both viscosity and surface tension are dependent on the intermolecular forces between the molecules of the liquid. Honey, while being more viscous then water, doesn’t have higher surface tension. Which has higher surface tension […]
