What will happen to the volume if pressure decreases? Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle’s law. When a rubber ball is taken […]
How strong can isometrics make you?
How strong can isometrics make you? Even the earliest studies of isometrics showed enormous strength gains, up to 5 percent per week. [5] Imagine doubling your strength in 20 weeks! It can be done and has been done using isometrics. You might be thinking, “Yeah, but isometric strength is only good when you’re not moving. […]
What are surveillance methods?
What are surveillance methods? Surveillance cameras are video cameras used for the purpose of observing an area. They are often connected to a recording device or IP network, and may be watched by a security guard or law enforcement officer. What are the two types of surveillance? There are two primary types of disease surveillance: […]
How much force is in a car crash?
How much force is in a car crash? According to GSU’s HyperPhysics Project, a 160 lb person—wearing a seat belt and traveling at only 30 miles per hour—experiences around 30 g’s of force in a front-end collision with a fixed object. That’s 2.4 tons of force acting on the body! How much force can a […]
Does animal cells have a nucleus?
Does animal cells have a nucleus? Animal cells Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts: Nucleus – This contains genetic material (DNA), and controls the cell’s activity. Cell membrane – A flexible layer that surrounds the cell and controls the […]

Answer: An object having 3kg is the most difficult to accelerate. Which object will have the greatest acceleration if acted upon by a net force of 100 […]
How do you calculate pressure exerted by gas?
How do you calculate pressure exerted by gas? Key Takeaways The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+… The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas. What is […]
Which of the following is needed to warm up 1g of any substance by 1 0c?
Is drag force equal to weight?
Does water reflect or absorb sound?
Does water reflect or absorb sound? As sound travels through a medium such as water, it gets absorbed – caught by the molecules within the medium. They do this by stealing some of the energy from the sound wave. The absorption in sea water is much greater than would be expected due to the viscosity […]
