Is force equal to mass? The net force on an object is equal to the mass of the object multiplied by the acceleration of the object. Or some simply say: Force equals mass times acceleration. Does force equal acceleration times mass? Newton’s second law of motion is F = ma, or force is equal to […]
What are two problems with static electricity?
What are two problems with static electricity? Here are some examples of dangers associated with static electricity: It is dangerous when there are flammable gases or a high concentration of oxygen. A spark could ignite the gases and cause an explosion. It is dangerous when you touch something with a large electric charge on it. […]
Who accurately measure the orbits of the planets?
Who accurately measure the orbits of the planets? Kepler’s Who give the concept of orbit? The basis for the modern understanding of orbits was first formulated by Johannes Kepler whose results are summarised in his three laws of planetary motion. What are called orbits? An orbit is a regular, repeating path that one object in […]
What are the directional terms of the human body?
What are the directional terms of the human body? Directional terms and body planes Anterior In front of or front Ventral Towards the front of the body Dorsal Towards the back of the body Distal Away or farthest away from the trunk or the point of origin of the body part Proximal Closer or towards […]
What are two measures of stock market performance?
What are two measures of stock market performance? The stock market is one of many different factors that economists consider when they look at economic health.

What two fruits make an orange?
What two fruits make an orange? The orange is a hybrid between pomelo (Citrus maxima) and mandarin (Citrus reticulata). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced. What is peeled orange called? The white that’s left behind on an orange after it’s […]
How is resistance and current related?
How is resistance and current related? Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance. Where do we use resistance? A resistor is a passive two-terminal electrical component that implements electrical resistance […]
Is UV catastrophe experimentally observed?
Is UV catastrophe experimentally observed? So energy density (intensity) would become infinitely large at the high frequency end of the spectrum, but experimentally observed that it approaches zero. This divergence for higher frequencies is called ultraviolet catastrophe. Hidden category: Physics stubs. What is Planck’s hypothesis? According to the Planck hypothesis, all electromagnetic radiation is quantized […]
What are three characteristics of the outer core?
What are three characteristics of the outer core? The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit). The liquid metal of the outer core has very low viscosity, meaning it is easily deformed and malleable. It is the site of violent convection. What is the […]
Can sulfuric acid dissolve rock?
Can sulfuric acid dissolve rock? Acid rain forms when rain combines with nitrogen and sulfur to create nitric and sulfuric acids, which can dissolve calcium-based rocks such as marble and limestone. What does sulfuric acid do to rock? Acids form readily in the soil. When sulfur dioxide combines with water, it forms the weak acid […]
