How does the working distance change when you increase the magnification? Working distance is how much space exists between the objective lens and the specimen on the slide. As you increase the magnification by changing to a higher power lens, the working distance decreases and you will see a much smaller slice of the specimen. […]
What are the two main studies of physical science?
What are the two main studies of physical science? In this lesson, we will discuss how physics and chemistry are considered to be the two main branches of physical science. We will also look at the overlap between physics and chemistry. What are the issues in science education? Some of the complex issues in the […]
How do you calculate the buoyant force of water?
How do you calculate the buoyant force of water? In general, the buoyancy force on a completely submerged object is given by the formula: FB=Vρg, where V is the volume of the object, ρ is the density of the fluid, and g is gravitational acceleration. What buoyancy means? 1a : the tendency of a body […]
Why is the mitochondria a bad organelle?
Why is the mitochondria a bad organelle? Because mitochondria are essential to so many cellular processes, when anything goes wrong with these organelles, they could be linked to many diseases. Recent discoveries have connected malfunctioning mitochondria to Parkinson’s, heart disease, diabetes, and cancer. What is the most important organelle in a plant? The Nucleus is […]
Where is UV found?
Where is UV found? UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. What is UV color? UV light has a shorter wavelength than visible light. […]
Why does oil make a rainbow in water?
How do muscles get oxygen?
How do muscles get oxygen? Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in […]
Is tens AC or DC?
Is tens AC or DC? A standard TENS unit typically delivers a low-frequency (<50 Hz) alternating current to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being […]
How do you do intervals on a histogram?
How do you do intervals on a histogram? To make a histogram, follow these steps: On the vertical axis, place frequencies. Label this axis “Frequency”. On the horizontal axis, place the lower value of each interval. Draw a bar extending from the lower value of each interval to the lower value of the next interval. […]
