What is the Oregon Trail now? The eastern part of the Oregon Trail spanned part of what is now the state of Kansas and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the current states of Idaho and Oregon. Did the Oregon […]
When should I worry about pipes freezing?
When should I worry about pipes freezing? The Minimum Temperature to Keep Pipes From Freezing Depending on their exposure to wind and the elements, pipes can freeze when temperatures are higher than 20 degrees. In interior spaces, if pipes are near cracks or openings that let in cold air, they may develop ice blockages even […]
Are electromagnetic waves beneficial or harmful?
Are electromagnetic waves beneficial or harmful? Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health. The focus of international research is the investigation of possible links between cancer and electromagnetic fields, at power line and radiofrequencies. What are the good effects […]
What should you do at a flashing yellow light?
What should you do at a flashing yellow light? When you see the yellow light, you should stop, if you can do so safely. If you can’t stop, look out for vehicles that may enter the intersection when the light changes. FLASHING YELLOW—A flashing yellow signal light warns you to be careful. Slow down and […]
What are the 9 regions of the body?
What are the 9 regions of the body? The nine regions are smaller than the four abdominopelvic quadrants and include the right hypochondriac, right lumbar, right illiac, epigastric, umbilical, hypogastric (or pubic), left hypochondriac, left lumbar, and left illiac divisions. The perineum is sometimes considered to be the tenth division. What are the 5 regions […]
What is an example of the James-Lange Theory?
What is an example of the James-Lange Theory? The James-Lange theory states that stimulating events trigger a physical reaction. The physical reaction is then labeled with a corresponding emotion. For example, if you run into a snake, your heart rate increases. James-Lange theory suggests that the increase in heart rate is what makes us realize […]
What is a simple definition of motion?
What is a simple definition of motion? In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. Thus, everything in the universe can be considered to be in motion. What is distance in science definition? Distance […]
What is causing the orbital velocity of object A to be increasing?
What is causing the orbital velocity of object A to be increasing? Inertia of the moving body tends to make it move on in a straight line, while gravitational force tends to pull it down. The more massive the body at the centre of attraction, the higher is the orbital velocity for a particular altitude […]
What is heat capacity explain?
What is heat capacity explain? Heat capacity is defined as the amount of heat required to raise the temperature of a mass of substance by 1°C. What is heat capacity in simple words? Heat capacity, ratio of heat absorbed by a material to the temperature change. It is usually expressed as calories per degree in […]
Does air expand when its hot?
Does air expand when its hot? As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. Do inert […]
