Do you need passenger side mirror? Under the California Vehicle Code, every vehicle registered in the state (except for motorcycles) is required to have at least two rearview mirrors. One of these mirrors must be on the vehicle’s left-hand side (driver’s side). When did they start putting passenger side mirrors on cars? 1960s Do cars […]

What is meant by LC circuit? An LC circuit is a type of an electric circuit that is made up of an inductor which is expressed by the letter L and a capacitor represented by the letter C. An LC circuit is also sometimes referred to as a tank circuit, resonant circuit, or tuned circuit. […]

Why is the faucet running slow? If your valves are open all the way and you’re still experiencing slow water flow, then the cause might be a clog. The first place to check is the aerator. The aerator is the cap on your faucet where the water comes out of. It has a screen and, […]

What is the difference between an actuator and a solenoid? Voice coil actuators are typically used in focusing applications, oscillatory systems, mirror tilting, and miniature position control. Solenoids consist of a coil that is contained in a ferrous steel housing and a movable steel slug or washer. An electromagnetic field is generated by current being […]

Can we see stars at night? Even though the stars that we see in the night sky are all very far away, we can see them not by actually being able to resolve their sizes, but by measuring the light that they produce. If we take the difference of the apparent and absolute magnitudes of […]

How many stars does the Milky Way galaxy have? 100 thousand million stars Is the Milky Way visible now? You can see the Milky Way all year, no matter where you are in the world. It’s visible just so long as the sky is clear and the light pollution is minimal. Can you see the […]

What is impulse write its formula? Impulse Equation Impulse is often stated to be the product of the average net force that acts on an object for a certain duration. The equation for impulse is given as; J = F⋅Δt. Note: We assume that force is constant over time. Impulse is a vector quantity like […]

Does increasing temperature decrease density? In general, the liquids tend to expand when their temperature increases. For example, the same mass of boiling water occupies more volume at 100 degrees Celsius than at 20 degrees Celsius. Therefore, increasing temperature decreases density. What affects mass flow rate? Considering the mass flow rate equation, it appears that […]

What is water cycle in one sentence? Water cycle is defined as the way that water moves between being water vapor to liquid water and then back to water vapor. An example of water cycle is when water evaporates from oceans and then returns to the land in the form of rain. What are called […]

What are the 7 basic units of measurement in the metric system? The seven SI base units, which are comprised of: Length – meter (m) Time – second (s) Amount of substance – mole (mole) Electric current – ampere (A) Temperature – kelvin (K) Luminous intensity – candela (cd) Mass – kilogram (kg) Do schools […]
