What forces act on a person jumping? Part II: The Jump Whether you are standing or jumping, the only external forces acting on your body are the normal force from the ground and gravity. How can you jump? Raising your center of mass into the air seems like it would require gravity to diminish or […]
What is the difference between membrane potential and resting potential?
What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]
What is 1 Joule equal to in Newton Metres?
Why does temperature increase volume?
Why does temperature increase volume? Another way to keep the pressure constant as the volume increases is to raise the average force that each particle exerts on the surface. This happens when the temperature is increased. So if the number of particles and the pressure are constant, temperature is proportional to the volume. When the […]
What force causes current to flow?
What force causes current to flow? Electric current is flow of electrons in a conductor. The force required to make current flow through a conductor is called voltage and potential is the other term of voltage. For example, the first element has more positive charges, so it has higher potential. What’s the minimum voltage at […]
Why is sediment transport important?
Why is sediment transport important? Sediment transport is applied to solve many environmental, geotechnical, and geological problems. Measuring or quantifying sediment transport or erosion is therefore important for coastal engineering. Movement of sediment is important in providing habitat for fish and other organisms in rivers. What are two ways water transports sediment? How do rivers […]
What are the advantages of a dynamic microphone?
What are the advantages of a dynamic microphone? Key advantages to a dynamic microphone: Rugged and able to handle high sound pressure levels, like those delivered by a kick drum. Provide good sound quality in all areas of microphone performance. They do not require a power source to run. They are relatively cheap. What do […]
What determines the period of a pendulum quizlet?
What determines the period of a pendulum quizlet? What determines the period of a pendulum? The length of the pendlum and the acceleration of gravity. The time it takes for a wave to complete one cycle. A long pendulum has a longer period than a shorter pendulum. Where is the most kinetic energy on a […]
What is the difference between 6ka and 10kA MCB?
What is the difference between 6ka and 10kA MCB? The main difference between the two is their capacity, with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps. How do you calculate kA rating? The maximum amount of current that can flow through a circuit is determined by the size […]
