How do you know if an image is real or virtual? (You will have no trouble remembering this if you think about it in the right way: a real image has to be where the light is, which means in front of a mirror, or behind a lens.) Virtual images are formed by diverging lenses […]
What would happen to pressure in the tire if some of the air were removed?
What would happen to pressure in the tire if some of the air were removed? The pressure inside the tire will keep on decreasing as more air leaks out of the tire because the number of air particles inside the tire decreases resulting in less collisions than before and due to the less frequent collisions […]
What is the value of 1 pico Farad?
What is the value of 1 pico Farad? 1/1,000,000,000,000 What is capacitance value? Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791–1867). A farad […]
What are 5 PPE?
What are 5 PPE? PPE includes gloves, gowns, laboratory coats, face shields or masks, eye protection, resuscitation masks, and other protective gear such as hats and booties. What is PPE and examples? Personal protective equipment, commonly referred to as “PPE”, is equipment worn to minimize exposure to a variety of hazards. Examples of PPE include […]
Why centrifugal force is called pseudo-force?
Why centrifugal force is called pseudo-force? The centrifugal force is a pseudo-force because if the centripetal force ceased for an object in circular motion, the centrifugal force the body is “feeling” would instantly disappear, and the object would travel tangentially to its line of motion. Can centrifugal force overcome gravity? The centrifugal force is real […]

What is a pulley system in physics?
What is a pulley system in physics? Pulleys are mechanisms compost by wheel and rope used to lift heavy objects onto tall heights. They change the direction of an applied force and they can even reduce the force needed to lift a weight. Pulleys systems are common used in constructions. What is the tension formula? […]
What is the amount of heat required to raise the temperature of 1 gram of water from 14.50 C to 15.50 C?
What happens when a ray of light strikes the surface of separation between the two media at right angle?
What happens when a ray of light strikes the surface of separation between the two media at right angle? What happens when a ray of light strikes the surface of separation between the two media at right angle? When light enters the boundary of two surfaces at right it passes normally without deviation. This is […]
