Is Strength training good for weight loss? Research shows that resistance training, whether done via body weight, resistance bands or machines, dumbbells or free weights, not only helps us build strength, but also improves muscle size and can help counteract age-related muscle loss. More recently it’s become popular among those looking to lose weight. How […]

Why self driving cars are not safe?
Why self driving cars are not safe? Self-driving cars may not be able to navigate through heavy rain or snowstorm that could hide or distort the painted lines on roads and highways. This can make autonomous navigation systems, if not useless, at least, erratic. Additionally, self-driving cars may give drivers a false sense of security. […]
What is the SI unit of light?
What is the SI unit of light? Candela How fast does light travel? 670,616,629 miles per hour Why is light faster than sound? Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel […]
What is a soft shadow?
What is a soft shadow? Figure 3.20 Hard-edged shadows indicate light from a small point source. In many cases, using soft shadows (which are less distinct and fade off toward the edges, as in Figure 3.21) for some of your lights tends to look more realistic than using only hard shadows. How do shadows change […]
Is gold a main group element?
Is gold a main group element? Examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon. Elements that are not main group elements are the transition metals (such as titanium, copper, and gold), the lanthanides (such as lanthanum and erbium), and the actinides (such as actinium and plutonium). What are […]
Will entropy ever stop increasing?
Will entropy ever stop increasing? Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. Why is entropy […]
What kind of energy is involved when ice melts?
What kind of energy is involved when ice melts? kinetic energy What happens to potential energy while the water is melting? When ice or any other solid melts, its potential energy increases. Indeed, this is the only increase in energy, since the thermal kinetic energy, or temperature, does not increase while melting. At each phase […]
Why is C 14 not used to date dinosaur bones?
Why is C 14 not used to date dinosaur bones? But carbon-14 dating won’t work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. To determine the ages of these specimens, scientists need an isotope with a very […]
What are 4 types of air masses?
What are 4 types of air masses? There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold. What are […]
