What is the difference between average acceleration and instantaneous acceleration? Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. What’s the definition of instantaneous speed? Definition: When the speed of an object is constantly changing, the instantaneous speed is the […]
What charge do humans have?
What charge do humans have? Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the […]
What comes first in trace conditioning?
What comes first in trace conditioning? a procedure in classical conditioning in which a conditioned stimulus and an unconditioned stimulus are separated by a constant interval (called the trace interval), with the conditioned stimulus presented first. What is the difference between forward conditioning and backward conditioning? Forward conditioning: Occurs when the neutral stimulus (NS) appears […]
Why is surface topography important?
Why is surface topography important? Surface topography refers to both the profile shape and the surface roughness (including the waviness and the asperity or the finish). Surface topography affects the film thickness to roughness ratio and the lubrication regime. These interactions become more important as the thickness-to-roughness ratio reduces. What is topography material? The topography […]
In which of the following cases is the electric field zero but potential is not zero?
In which of the following cases is the electric field zero but potential is not zero? 1. Electric field(E)=0 but Potential(V) is not 0: The electric field is zero at a point exactly midway between two equal and similar charges but the electric potential at that point is twice than that due to a single […]
Which of the following action best describes conserving water?
Which of the following action best describes conserving water? Water is best conserved if it is used judiciously. What is the most appropriate use for graywater? Greywater is suitable for irrigating lawns, trees, ornamentals, and food crops. Is laundry water GREY water? Greywater is the waste water from showers, baths, spas, handbasins, laundry tubs, washing […]

Does Red Cross pay for platelets?
Does Red Cross pay for platelets? Platelets can only be donated at select American Red Cross Donation Centers and it requires an appointment. You will be able to provide in one platelet donation what would normally be collected from up to five whole blood donations. In fact, some platelet donations yield enough platelets for two […]
How do you know seafloor spreading?
How do you know seafloor spreading? Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. What is the oldest seafloor? […]
