How do you create a positive charge? An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged. What is charge in simple […]
Can your brain heal from a concussion?
Can your brain heal from a concussion? Rest is very important after a concussion because it helps the brain to heal. You’ll need to be patient because healing takes time. Only when the symptoms have reduced significantly, in consultation with your doctor, should you slowly and gradually return to your daily activities, such as work […]
How do you know if its a proportional relationship?
How do you know if its a proportional relationship? To determine if a proportional relationship exists, you need to look for equivalent (equal) ratios within the table. If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. How do you […]
What happens if you just let the bob swing back and forth?
Is Carnot a cycle?
Is Carnot a cycle? The Carnot cycle consists of the following four processes: A reversible isothermal gas expansion process. In this process, the ideal gas in the system absorbs qin amount heat from a heat source at a high temperature Thigh, expands and does work on surroundings….T-S Diagram. Process ΔT ΔS IV Thigh−Tlow 0 Full […]
How can you obtain magnetic field pattern of a straight current carrying conductor?
How can you obtain magnetic field pattern of a straight current carrying conductor? Expert Answer: Take a thick straight conductor XY and pass it through the centre of a thick cardboard. Pass current through the conductor such that it flows from X to Y. Sprinkle some iron filings on the cardboard and gently tap. These […]
Is blood in your body blue until it touches oxygen?
Is blood in your body blue until it touches oxygen? Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That’s why blood turns bright cherry red when oxygen binds to its iron. But this is wrong; human blood is never blue. The bluish color of […]
What is the formula of potential difference between two points?
What is the effect of half wave plate on phase retardation?
What is the effect of half wave plate on phase retardation? By combining two waveplates whose retardations differ by exactly half a wave, a true half-waveplate is created. The fast axis of one plate is aligned with the slow axis of the other, so that the net retardation is the difference between the two retardations. […]
