What happens when you swing the bucket slowly when you swing it fast? In order for the bucket to keep falling with the water, the bucket must travel fast enough to keep up with the water. If you spin the bucket too slowly, the water will fall out and you will get wet. Why does […]

How do you know if two wires are attractive or repulsive? When the current goes the same way in the two wires, the force is attractive. When the currents go opposite ways, the force is repulsive. You should be able to confirm this by looking at the magnetic field set up by one current at […]

What are the 3 stages of river? Nearly all rivers have an upper, middle, and lower course. Young River – the upper course. Middle Aged River – the middle course. Old River – the lower course. What part of a river flows fastest? 1. Toward the middle of a river, water tends to flow fastest; […]

What force pushes atoms apart? the electromagnetic force Do disulfide bonds stabilize proteins? Disulfide bonds play a critical stabilizing role in many protein structures by forming cross-links between different regions of polypeptide chains. Do all proteins have disulfide bonds? Intramolecular disulfide bonds stabilize the tertiary structures of proteins while thoise that occur intermolecularly are involved […]

What are the 3 gases? Nitrogen, oxygen and argon are the three most abundant elements in the atmosphere, but there are other key components that are required for supporting life as we know it on earth. One of those is carbon dioxide gas. Carbon dioxide makes up 0.04 percent of the Earth’s atmosphere. What is […]

Which 3 minerals would melt first? Rock composition: Minerals melt at different temperatures, so the temperature must be high enough to melt at least some minerals in the rock. The first mineral to melt from a rock will be quartz (if present) and the last will be olivine (if present). What is it called when […]

What is the phase of the moon when 100% of the Moon is lit up? Full Moon How much is the moon bright side can you see during a new moon? At New Moon, the percent illuminated is 0; at First and Third Quarters, it is 50%; and at Full Moon, it is 100%. During […]

Can sunspots disappear? Most sunspots fade somewhat over time, but they will typically not disappear completely because the skin has been permanently damaged. There are, however, several treatments to diminish the appearance of sunspots. Bleaching creams and acid peels can make the appearance of sunspots less obvious. Do Sunspots appear when sun is active or […]

What will be the effect on the centripetal acceleration if both the speed and the radius of the circular path of a body are doubled? If both the speed of a body and radius of its circular path are doubled, then centripetal force also gets doubled. Is centripetal acceleration a constant vector? But, the direction […]

What are the 4 mythologies? Mythology: Greek, Roman, Norse, Egyptian, American Indian. What does the Omega tattoo mean? As a Christian symbol, the Alpha and Omega represent the eternal nature of Jesus Christ. Alpha and Omega are the first and last letters of the Greek alphabet.
