You should back-up your computer every few weeks (or as often as needed).
As soon as you suspect that your computer (or any other backup-able device) is too slow or "glitch-y" you should back-up your device before you lose any important files or data.
PREVENTING MALFUNCTION:
→ Always set your computer on a hard & flat surface.
→ Avoid downloading programs from unknown or non-trusted sources.
→ Avoid using your computer in a hot area.
→ Consider installing a virus/malware protection software on your computer.

Answer:
Viscosity - resistance to flow.
Magma has a higher viscosity if it has a lower temperature, is rich in silica, and contains a high abundance of dissolved gases.
Explanation:
Viscosity is referred to as a fluid's (liquid or gas) opposition or resistance to flow or change in shape. This resistance to motion or flow is caused by the internal friction between the molecules in the fluid. Viscosity denotes the thickness of the fluid. With increasing temperature, the viscosity decreases (thins) while with decreasing temperature, the viscosity increases (thickens).
Magma is a mixture of molten or liquid rock, crystals, dissolved gases, etc formed deep inside the earth and it causes volcanic eruptions when expelled onto the Earth's surface. The chemical composition of magma mostly contains silica, SiO2 (50 to 75% ) and iron, magnesium, sodium, potassium, and calcium form the rest. The magma contains dissolved gases and they give magmas their explosive behavior. The gas composition in magma consists of mostly water vapor and some carbon dioxide and traces of fluorine, sulfur and chlorine gases.
The viscosity of magma depends on the temperature, the composition of the magma and the amount of dissolved gases. As the SiO2 concentration in the magma increases, the viscosity also increases. The presence of a high amount of dissolved gases in magma also increases its viscosity. As the temperature of the magma increases, the viscosity decreases.
The rhyolitic type magma has a higher viscosity than the basaltic type magma and the andesitic type magma as it has a low temperature, rich in silica and contains a high abundance of dissolved gases.
Answer: Yes
The capacitor in an RC circuit (Resistor-Capacitance circuit) creates a time delay that decays exponentially. Therefore when the voltage to the bulb is removed, it takes a long time for the capacitor to completely discharge.
Although the brightness of the bulb will diminish as the capacitor discharges, the bulb will still be lit until the capacitor discharges to a voltage that is too low to sustain visible light (to the human eye) from the bulb.
