Can I connect 12v led to car battery? Answering your question: you can’t use a 12v battery to power a 12v led strip directly. a fully charged lead acid will have 13.8v which will burn out your led strip if you are doing so. You don’t need a current limited device. it will drop your […]
Do plants grow better in blue or red light?
Do plants grow better in blue or red light? Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit. It’s also essential to a plant’s early life for seed germination, root growth, and bulb development. Will plants grow under white […]
Does temperature affect water flow?
Does temperature affect water flow? In general, liquids tend to get “thinner” when their temperature increases. For example, honey and oil tend to flow better at higher temperatures. Does flow rate increase with temperature? In temperature programming, the flow rate will decrease as the column temperature increases. This decrease is due to the increased viscosity […]
How do you find the surface flux?
How do you find the surface flux? Find the flux of the vector field in the negative z direction through the part of the surface z=g(x,y)=16-x^2-y^2 that lies above the xy plane (see the figure below). Hence, the flux through the surface in the downward z direction is -128*pi cubic units per unit time. What […]
What are examples of interval variables?
What are examples of interval variables? An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850). Is age a nominal variable? Is Age Nominal or Ordinal Data? Age can be both nominal […]
What are maximum and minimum turning points?
What do you mean by net force?
What do you mean by net force? Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle’s motion. It gives the particle the same acceleration as all those actual forces together as described […]
How does velocity affect speed?
How does velocity affect speed? Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio. […]
What is the relationship between gas and pressure?
What is the relationship between gas and pressure? For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice […]
Where do we use maximum power transfer theorem?
Where do we use maximum power transfer theorem? The Maximum Power Transfer theorem is used to find the load resistance for which there would be the maximum amount of power transfer from the source to the load. The maximum power transfer theorem is applied to both the DC and AC circuit. What is the difference […]
