Is current directly proportional to voltage? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is relation between voltage and current? […]
What are 4 examples of renewable resources?
What are 4 examples of renewable resources? Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. What is the difference between usable and non reusable resources? Sunlight, water, wind, woods, forest, are the renewable resources. Petrol, coal, nuclear energy, […]
Which is older intrusion or extrusion?
Which is older intrusion or extrusion? Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath […]
What factors influence potential and kinetic energy?
What factors influence potential and kinetic energy? Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to […]
Why is graphite dangerous?
Why is graphite dangerous? Graphite is a form of pure carbon. It is not edible, but not chemically dangerous. Graphite can be made to be more dangerous than Pb depending on ingenuity. For instance if you powder graphite and force a person to breath the powder until they choke, it is more dangerous that a […]
What is the most common compound?
What is the most common compound? Glossary Compound Formula Abundance percent by weight Silicon dioxide SiO2 42.86% Magnesium oxide MgO 35.07% Ferrous oxide FeO 8.97% Aluminum oxide Al2O3 6.99% How do you know the difference between a compound and mixture? Compound:a substance that is made up of more than one type of atom bonded together. […]
What does constant velocity look like?
What does constant velocity look like? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. Given a graph as in, we can calculate the velocity from the change in distance over […]
What does a weather station record?
What does a weather station record? These weather stations measure a large variety of different meteorological parameters, including air temperature; atmospheric pressure; rainfall; wind speed and direction, humidity; cloud height and visibility. … Where is the best place to locate a weather station? Ideally mounted at a height of 4 to 6 feet above the […]
What are the 5 variables?
What are the 5 variables? There are six common variable types: DEPENDENT VARIABLES. INDEPENDENT VARIABLES. INTERVENING VARIABLES. MODERATOR VARIABLES. CONTROL VARIABLES. EXTRANEOUS VARIABLES. How many independent variables should an investigation have? one independent variable What’s the dependent variable in science? The dependent variable is the variable that is being measured or tested in an experiment. […]
Which is better if the discharge time of the capacitor is small or large?
Which is better if the discharge time of the capacitor is small or large? At first the current is large because the voltage is large, so charge is lost quickly and the voltage decreases rapidly. As charge is lost the voltage is reduced making the current smaller so the rate of discharging becomes progressively slower….Discharging […]
