What is the frequency and wavelength of a photon emitted during a transition from n 5 state to? What are frequency and wavelength of a photon emitted during a transition from n=5 state to n = 2 state in hydrogen atom? As n1= 2 and n2 = 5, this transition gives rise to a spectral […]

Can bullet fire if dropped? So no, a cartridge / bullet will not fire on dropping on the ground. For a cartridge to go off, the small cap at the base of the cartridge (the primer) needs to be struck by a hammer or firing pin – such is the firing mechanism of all conventional […]

What are the advantages of Tides Class 7? Advantages of High Tide: They help in navigation. They raise the water level close to the shores and help the ships to arrive at the harbor more easily. They help in fishing. More fish come closer to the shore during high tides. What is the importance of […]

Where is kinetic energy the greatest on a hill? As you begin to descend, your potential energy decreases until it’s all gone at the bottom of the hill.” “At the bottom of the first hill, your kinetic energy is at its highest point. How is kinetic energy affected by his speed? It turns out that […]

Where is critical listening used? We can be said to be engaged in critical listening when the goal is to evaluate or scrutinise what is being said. Critical listening is a much more active behaviour than informational listening and usually involves some sort of problem solving or decision making. What is critical listening Where do […]

What should manifold vacuum be at idle? Manifold vacuum is used to show engine compression and is created between the throttle plate and the intake valves. Normal manifold vacuum on an engine running at idle speed is around 18 to 20 inches. How much vacuum should a 350 have at idle? Idle vacuum for most […]

Is powdered chocolate a solute? The solution of hot chocolate becomes one mixture rather than powder and water. The substance that is being dissolved in another substance is called the solute. In this example, the hot chocolate powder is the solute. Is chocolate powder dissolve in hot water easily? Explanation: Hot water has more energy […]

What is the relation between upthrust and density of fluid? density is one factor affecting upthrust (buoyant force). if the density of the substance is more than the density of the fluid, then the upthrust will be less and thus the substance sink. if the density of the substance is less than the density of […]

How do you find the centrifugal force? How to calculate centrifugal force Find the mass of the object – for example, 10 kg . Determine the radius of rotation. Let’s assume it’s 2 m . Determine the velocity of the object. It can be equal to 5 m/s . Use the centrifugal force equation: F […]

What are the two conditions that make deception ethical? Deception in psychological research is often stated as acceptable only when all of the following conditions are met: 1) no other nondeceptive method exists to study the phenomenon of interest; 2) the study makes significant contributions to scientific knowledge; 3) the deception is not expected to […]
