Why is the corona hotter? Nanojets are thought to be initiated by a process called ‘magnetic reconnection’, where twisted magnetic fields explosively realign. One such reconnection can set off another, resulting in an avalanche of nanojets in the Sun’s corona, which is then thought to generate enough energy to heat the corona. What triggers lightning? […]
What is the formula for capacitance of a capacitor?
What is the formula for capacitance of a capacitor? The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used. How can you increase the capacitance of a parallel plate capacitor? The capacitance of a set of […]
How many hours of sun does a north-facing garden get?
How many hours of sun does a north-facing garden get? You’ll get quite a bit at the height of summer, I should think about 7 hrs a day ime, central England latitude — more if you’re further north. Obviously at the ends of the day (morning, early evening. Good aspect for a conservatory (won’t get […]
What is the volume of a 6cm Cube?
What does the L mean on a weather map?
What does the L mean on a weather map? low pressure What symbols are commonly found on a weather map? These often include temperature, dew point (a measure of humidity), wind speed, wind direction, present weather, barometric pressure and pressure tendency (is it rising or falling?), cloud cover, and many others. What is a key […]
What is the difference between voltmeter and voltmeter?
What is the difference between voltmeter and voltmeter? Ammeter and voltmeter are used to measure the flow of current and the measure of voltage, respectively….Difference Between Ammeter and Voltmeter. Ammeter Voltmeter Use The flow of current is measured using this instrument. Voltage or potential between two points in an electric circuit is measured using this […]
What are 2 types of mixture?
What are 2 types of mixture? Types of Mixtures There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. What are the 5 examples of mixtures? Here are a few more examples: Smoke and fog (Smog) Dirt and water (Mud) Sand, water and gravel (Cement) Water and salt (Sea water) Potassium nitrate, sulfur, […]
Which friction takes the most force to overcome?
Which friction takes the most force to overcome? sliding friction What are the 4 types of friction? Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. What friction do […]
Why is the electric field of dipole not zero?
Why is the electric field of dipole not zero? Why is electric field of dipole nonzero? Because the positive and the negative charges are separated by some distance. So though the a Gaussian surface enclosing the electric dipole has zero net charge the electric field in the region isn’t zero because there are separated charges […]
What are the elements of res ipsa loquitur?
What are the elements of res ipsa loquitur? As discussed, a successful negligence case requires the plaintiff to prove four elements: duty, breach of duty, causation, and damages. A res ipsa loquitur case covers the first three, namely, duty, breach of duty, and causation. What a reasonable person would do? The “reasonable person” is a […]
