What are long waves? Long waves, also called infragravity waves, have a wave period of 30 seconds to several minutes. Astronomical tides represent one important example of long waves. Long waves can occur in shallow water, such as the Chesapeake Bay. But long waves are not limited to what is normally considered shallow water. What […]
How many different types of batteries are there?
How many different types of batteries are there? three types What is the main function of a battery? A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The […]
How long must you boil water to make it safe to drink?
How long must you boil water to make it safe to drink? Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water […]
What material expands the most when heated?
What material expands the most when heated? By contrast, iron, with a coefficient of 1.2, is 24 times more likely to expand or contract as a result of changes in temperature. (Steel has the same value as iron.) The coefficient for aluminum is 2.4, twice that of iron or steel. Which state of matter contracts […]
What force is used to lift a weight?
What are three primary methods of monitoring volcanic activity?
What are three primary methods of monitoring volcanic activity? Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is … How can we detect […]
Why is it possible to use physical properties to separate a mixture?
Why is it possible to use physical properties to separate a mixture? The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances. What are three physical properties used to separate mixtures? Physical […]
Which graph shows the motion of the car?
Which graph shows the motion of the car? The speed-time graph represents the motion of a car travelling along a straight level road. What is secondary motion SSM? Secondary motion is totally event-dependent. Tertiary motion is especially fast object motion. Who decides the agenda for a meeting? Who Should Create the Meeting Agenda? Board meeting […]
What is the angle between the two vectors?
What is the angle between the two vectors? “Angle between two vectors is the shortest angle at which any of the two vectors is rotated about the other vector such that both of the vectors have the same direction.” Furthermore, this discussion focuses on finding the angle between two standard vectors, which means their origin […]
How can you classify mixture?
How can you classify mixture? Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties. These properties can be used to separate the components by filtering, boiling, or other physical processes. Can you still recognize salt from […]
