What are the six properties of ionic compounds? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Why are covalent […]
What is the formula for pulleys?
What is the formula for pulleys? Calculate the force caused by gravity on the basic pulley system using the following equation: G = M x n (gravitational acceleration). The gravitational acceleration is a constant equal to 9.8 m/s². The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. […]
What are the three factors to consider in the flow of electrons?
What are the three factors to consider in the flow of electrons? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. What’s another word for current […]
How many sensors must be energized before the air bag will deploy?
How many sensors must be energized before the air bag will deploy? Two sensors Can airbags go off without power? Can an airbag go off without power? Yes. Airbags have an internal electrical capacitor that is capable of setting off the airbag even if you switch off the ignition or disconnect the battery. Can an […]
Why has my energy bill doubled?
Why has my energy bill doubled? Your energy bill usually reflects the amount of energy you’ve used. It’s normal for your bill to increase if, for example, you start: putting the heating on more often. using a tumble dryer or electric heater. Does heater or AC use more electricity? The simple answer to your first […]
What is range and how is it calculated?
What causes velocity to decrease?
What causes velocity to decrease? Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that […]
Is Ballistic an exact science?
Is Ballistic an exact science? Ballistic is the science of the motion of the projectile and the condition that affects their motion. Ballistics is not an exact science rather it is branch of physics or applied science which is subject to changes and development depending upon the demands of the modern civilization. Does ballistic mean […]

What is a service and its characteristics?
What is a service and its characteristics? The defining characteristics of a service are: Intangibility: Services are intangible and do not have a physical existence. Hence services cannot be touched, held, tasted or smelt. This is most defining feature of a service and that which primarily differentiates it from a product. What are the main […]
