Will we ever be able to travel faster than light? Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our […]

What are the 2 branches of the autonomic nervous system?
What are the 2 branches of the autonomic nervous system? The autonomic nervous system has two main divisions: Sympathetic. Parasympathetic. Can you control autonomic nervous system? While involuntary physiological processes are usually outside the realm of conscious control, evidence suggests that these processes, through regulation of the autonomic nervous system, can be voluntarily controlled. Is […]
How much activity is considered active?
What makes good insulation?
What makes good insulation? Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can’t flow through them. This stops the movement of air in the space between the two layers of glass and reduces heat loss from […]
What is an example of experimental control?
What is an example of experimental control? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. How do you show experimental […]
What does the orange and white buoy mean?
What does the orange and white buoy mean? These special-purpose buoys have orange symbols on white pillars, cans, or spars. They are used to: Give directions and information. Warn of hazards and obstructions. What side do you pass a red buoy on? right What color is a marker that indicates safe water? Safe Water Markers: […]
What are the problems with DNA evidence?
What are the problems with DNA evidence? DNA evidence is only as reliable as the procedures used to test it. If these procedures are sloppy, imprecise, or prioritize particular results over accuracy, then the so-called “DNA evidence” they produce cannot be a trustworthy basis for a conviction. What are the 4 basic steps of DNA […]
What type of relationship exists between the length of wire in the resistance if all other factors remain the same?
What type of relationship exists between the length of wire in the resistance if all other factors remain the same? What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? Resistance is directly related to length. What type of relationship exists between the length […]
Is the moon dying?
Is the moon dying? The moon isn’t “dead” after all. Newly discovered ridges on the moon’s surface are leading scientists to think that the moon might have an active tectonic system. These ridges, speckled with boulders, could be evidence that, not too long ago, tectonic activity broke apart the moon’s surface. Is Moon cracked? In […]
