Can sulfur form ionic bonds? Sulfur, which only needs two electrons to complete it octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion, S2− , in the process. The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together → an ionic bond is formed. […]

What are the disadvantages of full wave rectifier? Disadvantages of full-wave rectifier: More complected than half-wave rectifier. It requires more diodes, two for center tap rectifier and four for bridge rectifier. PIV rating of the diode is higher. Higher PIV diodes are larger in size and too much costlier. The cost of the center tap […]

What 2 forces act on a falling object? A falling object in the air, which is not influenced by wind or other sideways forces, has a maximum of two forces acting on it: weight and air resistance (also known as drag). The weight does not change. The air resistance is zero when the object is […]

What are the 5 types of consumers? Following are the most common five types of consumers in marketing. Loyal Customers. Loyal customers make up the bedrock of any business. Impulse Shoppers. Impulse shoppers are those simply browsing products and services with no specific purchasing goal in place. Bargain Hunters. Wandering Consumers. Need-Based Customers. What are […]

How do you microwave food without it getting soggy? To keep foods like sandwiches, french fries, bread rolls, etc. from getting soggy when heating in your microwave, you should wrap them in a dry paper towel to absorb the moisture when they are being heated (see costs and reviews of paper towels). How long should […]

What is the difference between a sprain and a strain? The difference between a sprain and a strain is that a sprain injures the bands of tissue that connect two bones together, while a strain involves an injury to a muscle or to the band of tissue that attaches a muscle to a bone. Should […]

Is Sonic Boom faster than sound? Sonic boom is an impulsive noise similar to thunder. It is caused by an object moving faster than sound — about 750 miles per hour at sea level. When the aircraft exceeds the speed of sound, these pressure waves combine and form shock waves which travel forward from the […]

Are force pairs always equal? According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. What is the first law of motion class 9th? The first law of motion is stated as: An object […]

Why are there two shadows? Two shadows are formed when there are two light sources striking on the same opaque body. If there is only one source of light then the other source might have come from a reflective body such as a mirror or other similar reflective bodies. How do you face your own […]

What is the wavelength of an electron of energy 20 eV? m = 0.0275 nm. What is the broccoli wavelength of an electron whose kinetic energy is 120 eV? Answer. Therefore, the de Broglie wavelength of the electron is 0.112 nm. What is the wavelength of an electron whose kinetic energy is 120 eV? Thus […]
