Which frozen liquid melts the slowest? Water melted the slowest with an average of 145 minutes. Next was sweet tea, which melted in 119 minutes. Do frozen liquids melt at the same rate? A 1 pound block of ice and 1 pound of ice cubes melt at very different rates. The only difference between the […]
Do longer wavelengths have low energy?
Do longer wavelengths have low energy? Related to the energy and frequency is the wavelength, or the distance between corresponding points on subsequent waves. Shorter waves move faster and have more energy, and longer waves travel more slowly and have less energy. Why do short waves have high energy? “Short wavelength” is the same as […]

What are the advantages of interdisciplinary studies?
What are the advantages of interdisciplinary studies? Interdisciplinary programs draw from two or more academic disciplines that work together to create a powerful learning experience and emphasize integrative learning, critical thinking, and creative problem solving. What is the main aim of interdisciplinary research? 20) What is the main aim of interdisciplinary research? Explanation: Particularly in […]
How much power does a train engine generate?
How much power does a train engine generate? How many horsepower is a diesel locomotive? A locomotive’s diesel engine is connected to an electric generator that is either DC or AC. In either case, the power produced is around 3,200 horsepower. The generator uses this power to convert it into a massive amount of current, […]
Does density affect specific weight?
Does density affect specific weight? Mass is a property and the SI unit for density is [kg/m3]. The Imperial (U.S.) units for density are slugs/ft3 but pound-mass per cubic foot – lbm/ft3 – is often used….Specific Gravity for some common Materials. Substance Specific Gravity – SG – Hydrogen 0.00009 Lead 11.35 Mercury 13.59 Nickel 8.73 […]
When a negative charge is released in a uniform electric field it moves to a position of?
When a negative charge is released in a uniform electric field it moves to a position of? Whe a negative charge is releases and moves in electric field , it moves toward a position of – Negative charge particle will move opposite to electric field means towards higher potentia and towards lower potential energy . […]
Can mining ever be sustainable?
Can mining ever be sustainable? Mining can become more environmentally sustainable1 by developing and integrating practices that reduce the environmental impact of mining operations. Why is mining not sustainable? “Mining is inherently unsustainable: It is destructive to the biophysical environment, and its contributions to human well-being are uneven and often overwhelmed by the social and […]
How do you describe a distance time graph?
How do you describe a distance time graph? If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the […]
What happens to the force of attraction when?
What happens to the force of attraction when? Hence force of attraction will be quadrupled. (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times. How many G’s […]
