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 the angle of reflection when the incident ray makes an angle of 30 0 with i the normal II the mirror?
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 […]
Can 2 remote control cars same frequency?
Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
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 […]
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 is the relationship between resistance and current?
What is the relationship between resistance and current? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is the property of […]
What is solid to a gas called?
What is solid to a gas called? The solid-to-gas change is called sublimation, while the reverse process is called deposition. Sublimation is isothermal, like the other phase changes. There is a measurable energy change during sublimation; this energy change is called the enthalpy of sublimation, represented as ΔH sub. What are 3 examples of sublimation? […]
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 […]
