What is Ampere formula? Since power is defined as the product of current and voltage, the ampere can alternatively be expressed in terms of the other units using the relationship I = P/V, and thus 1 A = 1 W/V. Current can be measured by a multimeter, a device that can measure electrical voltage, current, […]

What are the two types of investigations? Scientists use three types of investigations to research and develop explanations for events in the nature: descriptive investigation, comparative investigation, and experimental investigation. How do I know if HMRC are investigating me? You will not be notified by HMRC as soon as it is looking into your affairs […]

What is an example of drive reduction theory? Thirst, hunger, and the need for warmth are all examples of drives. A drive creates an unpleasant state, a tension that needs to be reduced. In order to reduce this state of tension, humans and animals seek out ways to fulfill these biological needs. We get a […]

Can you compare two vectors? If contents of vectors are equal than it will return true else false. It will compare all the elements in vector, we can not compare the sub sections of vectors using it. It will compare all the elements in vector, by calling operator == on each element. What has both […]

How do you describe the sound of water? The verb burble captures both the movement of the water and the sound it makes as it moves. You could also say that a brook or stream or river babbles or ripples or even trickles. The word burble was first used in the 1300’s, and it probably […]

What is an example of absolute location? A place’s absolute location is its exact place on Earth, often given in terms of latitude and longitude. For example, the Empire State Building is located at 40.7 degrees north (latitude), 74 degrees west (longitude). How do you describe a site location? The “site” is the actual location […]

What is the best way to bring a car out of a skid? Regardless of whether the vehicle has front-, rear- or four-wheel drive, the best way to regain control if the front wheels skid is: Take your foot off the brake if the front wheels skid due to hard or panic braking. Ease your […]

Can alkali metals react with nitrogen? Of the alkali metals, only lithium reacts with nitrogen, and it forms a nitride (Li3N). In this respect it is more similar to the alkaline-earth metals than to the Group 1 metals. Lithium also forms a relatively stable hydride, whereas the other alkali metals form hydrides that are more […]

Is heat from a fire radiation or convection? The thermal radiation from the fire spreads out in all directions and is able to reach you. This thermal radiation is mostly in the form of infrared waves and visible light. In contrast, the campfire heat transferred via convection shoots straight up into the sky and never […]
