When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

What are two examples of the Doppler effect? The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect. Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect. Where is the Doppler effect used? Doppler […]

What is the ratio of kinetic energy and potential energy of a satellite? For the satellite moving in an orbit around […]

Why might a bright yellow solid form when two clear colorless liquids are mixed? Explanation: When two substances (can be aqueous or liquids) in solution react, they yield a solid and an aqueous compound. This is a double displacement reaction in which the solid is known as a precipitate. Can two solids react to form […]

What is the SI unit of only current? ampere Can I use 110v in USA? It will be just fine, as long as your electricity is running to US spec. It really can be anywhere from 110V to 120V +/- 5%. Can I plug 120V into 110v? In the US, 110V isn’t a standard voltage. […]

How do you use the word use and used? Used to refers to something familiar or routine, as in “I’m used to getting up early for work,” or to say that something repeatedly happened in the past like “we used to go out more.” Use to typically occurs with did; “did you use to work […]

Can plate tectonics be proven? What is the cause of plate tectonics? Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. What are the evidences […]

How far can a load extend beyond your car? The load must not extend more than 1.275 metres either side from the centre line of the vehicle. The maximum width of the vehicle is 2.55m. If your load extends behind the back of your vehicle by more than 1m then you’ll need to attach a […]
