Which drum makes a sound that fades away faster? Fading away of sound waves depends on the wavelength of the sound. The one that has a loud sound with high frequency will have a brighter sound. While the more mellow one will have the bassier sound. Therefore, the sound with a more mellow sound will […]

What does reason stand for in life skills? REASON acronym. context. The circumstances, atmosphere, attitudes, and events surrounding a text. You just studied 23 terms! What does the reason acronym stand for in business? Response and Effects Analysis System for Operational Needs What does responsible stand for? Responsibility. Being responsible means being dependable, keeping promises […]

What is centripetal force equal to? The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion, for every action there is an equal and opposite reaction. Why […]

What are the types of systematic errors? Systematic errors may be of four kinds: Instrumental. For example, a poorly calibrated instrument such as a thermometer that reads 102 oC when immersed in boiling water and 2 oC when immersed in ice water at atmospheric pressure. Observational. For example, parallax in reading a meter scale. Environmental. […]

Can K-type stars support life? K stars can live for 17 to 70 billion years, much longer than sunlike stars, which shine on the main sequence for only about 10 billion years. The longer lifespan of a K star would give life on an orbiting planet more time to evolve, if it ever got started. […]

What is the relationship between mass and weight of an object? Mass is a measure of how much matter there is in an object, while weight is a measure of the size of the pull of gravity on the object. Mass is the amount of matter in an object. Mass is measured in kilograms (kg). […]

What if Earth had no tilt? The tilt of Earth’s axis is the main cause of the seasons. If Earth had no tilt, then the length of daylight and the intensity of solar heating seen by a person standing at a single place on the surface would be the same all year round. What if […]

What are the negative effects of technology in the workplace? Distraction is one of the most harmful impacts of technology at the workplace. The result? Cognitive scientist Gloria Mark says, is, people compensating for interruptions by working faster, leading to stress, frustration and pressure. All of this leads to poor productivity. Why the technology is […]

The union symbol ( ) denotes the union […]

What is the significance of Thevenin equivalent circuit? Thevenin’s Theorem is especially useful in analyzing power systems and other circuits where one particular resistor in the circuit (called the “load” resistor) is subject to change, and re-calculation of the circuit is necessary with each trial value of load resistance, to determine voltage across it and […]
