Is the air we breathe an element? Air is nothing but a mixture of a variety of gasses. The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). What elements are in our air? […]
What happens if the ball hits directly on the end line?
What happens if the ball hits directly on the end line? What happens if the ball hits directly on the endline? The ball may only be contacted 2 times before returning over the net. What are the most important cues when blocking? Penetrating the Net (Blocking is counter attacking) Penetrating the net is considered the […]
What is the condensation sequence?
What is the condensation sequence? Definition. In planetary science, the condensation sequence refers to the order in which chemical compounds transition from gas to solid phase in a protoplanetary nebula (disk), based on the condensation temperature of each compound. Why is dust important to the condensation sequence? Why is dust important to the condensation sequence? […]
What are the 3 main phases of a warm up?
What are the 3 main phases of a warm up? A warm up generally consists of a gradual increase in intensity in physical activity (a “pulse raiser”), joint mobility exercise, and stretching, followed by the activity. For example, before running or playing an intensive sport, athletes might slowly jog to warm their muscles and increase […]
Are voltage and current proportional?
Are voltage and current proportional? By Ohm’s Law, Current (I) is directly proportional to the Voltage (V) if Resistance (R) and Temperature remain constant. According the power formula, It says that Current is inversely proportional to the voltage if power remain same. What happens if voltage is tripled? Any alteration in the voltage will result […]
What is organic gold?
What is organic gold? Organic Gold is the Gold that comes to the surface and could be found in river banks and different grounds by light digging and hand fossicking as opposed to non-organic gold that is very aggressively dug up by big mining machines, digging down kilometers into the ground, moving thousands of truckloads […]
Can you connect batteries in series and parallel at the same time?
Can you connect batteries in series and parallel at the same time? It is also possible to connect batteries in series and parallel configuration. Therefore, you can connect two parallel connections in a series as you would two batteries. Only one cable is needed; a bridge between a positive terminal from one parallel bank to […]
Does energy have temperature?
Does energy have temperature? Temperature is a measure of the average kinetic energy of the particles in an object. Thermal energy is the total energy an object has due to the internal motions of its particles. The temperature is related to the average kinetic energy—not the total kinetic energy. How do you calculate temperature change? […]
What is the resistance of a coolant temperature sensor?
What is the resistance of a coolant temperature sensor? In cold engine and an ambient temperature of 20 ºC the sensor resistance is between 2000Ω and 3000Ω. After the engine start, coolant temperature begins to rise. ECT gradually heats and its resistance reduces proportionately. At 90 ºC its resistance is in the range of 200Ω […]
Which of these require a medium?
Which of these require a medium? Mechanical waves require a material medium for their propagation and cease to propagate in the absence of a material medium such as a solid, liquid or gas. Since, sound waves are an example of mechanical waves; thus, they require a medium for their propagation. Thus, option (D) is the […]
