Can you get cancer from sitting in front of a heater? We know what it is, but there have been very few direct sources of interference to the natural body functions, that result in the mutations of the cell divisions, that is commonly called ‘cancer’. Sitting in front of an “infra Red” heater, is not […]
What is the effect of unbalanced forces?
What is the effect of unbalanced forces? An unbalanced force can change an object’s motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving. What would the resultant force on an […]
Why autonomous systems are important?
Why autonomous systems are important? Advantages of autonomous systems are their ability to go into places and situations where humans cannot. This includes dangerous places, such inspecting inside nuclear reactors to check for faults, and inaccessible places, such as inside aero-engines. What does autonomous mean? 1a : having the right or power of self-government an […]
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 […]
What are the possible sources of error in a bomb calorimetry experiment?
What are the possible sources of error in a bomb calorimetry experiment? Sources of error include the percent error in water measurement and incomplete vaporization of the nichrome wire. The internal volume of the Parr-bomb was measured to be 341mL. Why is benzoic acid used to calibrate a bomb calorimeter? Benzoic acid (C6H5CO2H) is often […]

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 […]
