What happens if velocity is constant? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its trace over time. Can a […]
Are stronger magnets the ones with more domains or the ones with fewer?
Are stronger magnets the ones with more domains or the ones with fewer? Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece […]
Is 45 degree water hot?
Is 45 degree water hot? In some strange parts of the world, 45 degrees Celsius is 114 in the United States, 316.16 in Switzerland, and 572.67 on the Rankine scale. It is mind numbingly hot for people who don’t care for the metric system. Can you touch 60 degree water? The industry standard is 60 […]
What are the main agents of mechanical weathering?
What are the main agents of mechanical weathering? The important agents of mechanical weathering are: The decrease in pressure that results from removal of overlying rock. Freezing and thawing of water in cracks in the rock. Formation of salt crystals within the rock. Cracking from plant roots and exposure by burrowing animals. What is the […]
What is the temperature of an object?
What is the temperature of an object? The temperature of an object relates to both the kinetic energy of its particles and the number of particles. Temperature is the average kinetic energy of the particles in a substance. When two objects touch the direction of heat transfer will go from? Conduction occurs when two objects […]
Do electromagnetic waves carry energy?
Do electromagnetic waves carry energy? An electromagnetic wave, although it carries no mass, does carry energy. It also has momentum, and can exert pressure (known as radiation pressure). The energy carried by an electromagnetic wave is proportional to the frequency of the wave. Can electromagnetic waves be polarized? Electromagnetic waves are transverse, and can be […]

The oldest tortoise – indeed animal – in the world is believed to be Jonathan, an 187-year-old giant tortoise who lives in St Helena. “Any other tortoise lives […]
Why is dual nature of light?
Why is dual nature of light? Wave-Particle Duality At this point, scientists had some experimental evidence (diffraction and interference) that indicated light was a wave and other experimental evidence (black body radiation and the photoelectric effect) that indicated light was a particle. Do light has dual nature? The dual nature of light has been extended […]
Which two gases Cannot be broken down by chemical means?
Which two gases Cannot be broken down by chemical means? Answer Expert Verified The answer is (2) CO and NH3. The chemical reaction can only break down chemical bonds between atoms inside the molecule. The He and Xe is consists of one atom only, so they can not be broken down by chemical means. Which […]
