What is the best way to protect your house from lightning strikes? Here are four ways to protect your home from lightning: Use a home lightning protection system. Unplug electronics and appliances. Install transient voltage surge suppressors. Check your homeowners and renters insurance coverage. Do you need a lightning rod on a metal roof? In […]
What are the similarities and differences of nuclear reactions?
What are the similarities and differences of nuclear reactions? Major differences between nuclear and chemical reactions (1) Nuclear reactions involve a change in an atom’s nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. Who is father of […]
Why does the voltmeter read 0?
Why does the voltmeter read 0? o If there is no source of electricity or resistance between the connections of the voltmeter it will read zero, since no potential difference exists between the two points. How do I calculate EMF? If we know the resulting energy and the amount of charge passing through the cell. […]
How long do mice stay in shock?
How long does it take for peat to turn into coal?
How long does it take for peat to turn into coal? about 12,000-60,000 years Why is peat not considered a fossil fuel? Peat is sometimes considered a “slowly renewable energy” and is classified as a “solid fossil” rather than a biomass fuel by the Intergovernmental Panel on Climate Change (IPCC). Although peat is not strictly […]
Should multimeter always be parallel when measuring current?
Should multimeter always be parallel when measuring current? A multimeter must be connected in parallel in a circuit (see diagram below) in order to measure voltage. So this means the two test probes should be connected in parallel with the voltage source, load or any other two points across which voltage needs to be measured. […]
What nationality has freckles?
What nationality has freckles? Freckles – they are an immediately recognisable “Irish” trait, up there with blue eyes and red hair. And they have been around for a long time: fossils found recently in China show that even some dinosaurs had freckled colouring. Why do some people get freckles and others don t? People with […]
What is the fastest you can travel in space?

As of the 27th of September 2020, the Parker Solar Probe has already accelerated to a speed of 289,927 mph (466,592 km/h) relative to the Sun, officially becoming the fastest spacecraft to […]
What can I use to melt gold?
Does boiling point affect conductivity?
Does boiling point affect conductivity? Sodium, magnesium and aluminium are good electrical conductors because of the ‘sea’ of delocalised electrons they possess. The melting (and boiling) points increase because the number of electrons each atom contributes increases. … What is the melting point of CUCL? 798.8°F (426°C) Which has more melting point NaCl or CuCl? […]
