What are the three types of collisions? Collisions are of three types: perfectly elastic collision. inelastic collision. perfectly inelastic collision. Which formula is used to find an object’s acceleration? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure […]

What is the difference of the volume of the two oblique pyramids? The formula for the volume of the pyramid is, V = [1/3](area of the base)*height. 1.17 rounded to nearest tenth is 1.2. What is the volume of the pyramid the oblique pyramid has a square base? The oblique pyramid has a square base. […]

How much does it cost to replace a vent valve? The cost to replace a purge valve in your car is generally between $110-$170, with the parts being the expensive price of the replacement, coming in at an average of $75-$110, while the labor usually only runs at about $50, meaning this is a quick […]

How are waves similar and different? Different waves, same properties All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. What do electromagnetic waves have in common? They […]

Is 5ms good for gaming? As a casual gamer, 5ms response time is more than enough for your simple gameplay of shooter games or racing or open world or RPG, it doesn’t matter. You will get a response time faster than your reflexes so you don’t have to worry about response time. Is 60Hz 1ms […]

Can your body get stuck in fight or flight mode? The body begins to tire, the immune system declines, and as we have learned in recent research, the brain can even begin to become toxic. Until the bone is returned to its proper position, and range of motion the body is likely to be stuck […]

Does the temp affect the bounce of a ball? One factor that can influence the bounce of a ball is the temperature of the ball. A warmer ball will bounce higher than a cold one. The reason for this is twofold. In a hollow ball, the change in temperature causes a change in air pressure […]

How do you compare two sample variances? F Test to Compare Two Variances If the variances are equal, the ratio of the variances will equal 1. For example, if you had two data sets with a sample 1 (variance of 10) and a sample 2 (variance of 10), the ratio would be 10/10 = 1. […]

How do you explain diffusion? What is diffusion? Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move […]
