Why is it easier for humans to walk through air than liquid water? It is easier to push an object through air than through water. This is because air is less dense than water. Since air is less dense this means there is less matter, or less “stuff”, in a certain area of air than […]
What is negative acceleration called?
What is negative acceleration called? The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement. What is negative acceleration in simple words? According to our principle, when an object is slowing down, the acceleration is in the […]
What is the direction of the electric field in the rod?
What is the direction of the electric field in the rod? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a […]
What gases are least ideal?
What gases are least ideal? 1 Answer. Sulfur dioxide should be the least volatile, have the greatest intermolecular interaction, and thus its behaviour is LEAST like the ideal. What is the difference between ideal gas and non ideal gas? Real gas and Ideal gas. As the particle size of an ideal gas is extremely small […]
What is the chemical name of ch2?
What is the chemical name of ch2? Methylene Why is CH2 called methylene? Methylene was used as the name for methanol, which is wood alcohol, CH3OH, in the early 19th century. Methylene comes from methe + hyde the latter being the Greek word for wood, so methylene would mean wine from wood. What is full […]
Can aluminum be magnetized?
Can aluminum be magnetized? In our everyday experience aluminum doesn’t stick to magnets (neither does copper). Most matter will exhibit some magnetic attraction when under high enough magnetic fields. But under normal circumstances aluminum isn’t visibly magnetic. Why is stainless steel jewelry so cheap? Stainless steel not only mimics the look of fine, precious metal, […]
What are the factors affecting the solubility?
What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
What will make an object move in a circular path?
What will make an object move in a circular path? A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal […]
How does light act like a particle?
How does light act like a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but […]
What are the major causes of freshwater pollution?
What are the major causes of freshwater pollution? Pollution may be caused by fecal waste, chemicals, pesticides, petroleum, sediment, or even heated discharges. Polluted rivers and lakes are unfit for swimming or fishing; polluted water is unsafe to drink. How does water use impact the environment? Less Water Affects the Environment When reservoir water levels […]
