When you reach the top of your jump on a trampoline? Your kinetic energy is greatest, just before you hit the trampoline on the way down and when you leave the trampoline surface on the way up. Your kinetic energy is 0 when you reach the height of your jump and begin to descend and […]
Why do protons carry a positive charge?
Why do protons carry a positive charge? Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. The positive charge on a proton is equal in magnitude […]

What do energy pyramids show?
What do energy pyramids show? An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. In other words, an energy pyramid shows how much energy is available at each trophic level. Energy is lost at each trophic level of a food chain. How does energy flow […]
What are the three types of collisions?
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 […]

How are waves similar and different?
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 […]
Can your body get stuck in fight or flight mode?
Can 200 decibels kill a human?
Can 200 decibels kill a human? Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and […]
What is the main function of solenoid valve?
What is the main function of solenoid valve? Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring. What […]
