What type of energy is stored in an unlit match? potential energy Which best explains Taros error? Which best explains Taro’s error? The total energy of the system remains the same. The human body stores chemical energy from digested food. Some of the chemical energy is converted into mechanical energy when the body moves. Which […]
What does it mean when an object does not slip?
What does it mean when an object does not slip? It means the object moves uniformly in one direction along the surface, with no angular velocity about the object’s own center of mass. What does it mean when a ball rolls without slipping? Rolling without slipping is a combination of translation and rotation where the […]
Is Earth a perfect sphere?
Is Earth a perfect sphere? Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round. Why […]
How do you calculate the no load speed of a DC motor?
How do you calculate the no load speed of a DC motor? By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and […]
What do the arrows in a food chain represent quizlet?
What do the arrows in a food chain represent quizlet? Food chains show which organisms eat other organisms. The arrows represent the direction of the transfer of energy from one organisms to the next. What causes the arrows to move in this direction? The earth’s rotation causes a phenomenon called Coriolis effect. The lower latitudes […]
Why is current constant in a parallel circuit?
Why is current constant in a parallel circuit? Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit). Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total […]
Is Lemon juice is a good conductor of electricity?
Is Lemon juice is a good conductor of electricity? When lemon juice is added to water, the acid dissociates into anions and cations which are charged. Hence they can conduct electricity as these charged particles are able to flow inside the acid. Hence when the salt or lemon juice is mixed in distilled water it […]
Which angle of light will heat the wood the most?
Which angle of light will heat the wood the most? 90° angle Why can you see objects placed under a heat lamp which emits infrared radiation? Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can […]
What are the 8 types of joints?
What are the 8 types of joints? Planar, hinge, pivot, condyloid, saddle, and ball-and-socket are all types of synovial joints. Is the wrist a gliding joint? Gliding joints occur between the surfaces of two flat bones that are held together by ligaments. Some of the bones in your wrists and ankles move by gliding against […]
Why is ecological footprint bad?
Why is ecological footprint bad? The ecological footprint is a measure of the resources necessary to produce the goods that an individual or population consumes. Finally, the lack of correlation between land degradation and the ecological footprint obscures the effects of a larger sustainability problem. What causes a high ecological footprint? Resource consumption such as […]
