What are three types of mechanical energy? Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Is riding a bike an example of mechanical energy? When you ride a bicycle, several things happen that require energy and it’s transformation. You pedaling the bike is transforming chemical energy, […]

Is Lambda slower than EC2? Lambda container can be spun up based on each request. However, it will involve cold start time, which is not significant compared to the EC2 instance setup time. So, for this use case, Lambda will have more latency per request than EC2 but significantly less than the EC2’s first request. […]

What kind of simple machine is a doorknob? wheel and axle What simple machine would help her move the shingles? pulley Is a doorknob a lever? A doorknob is a simple machine that only has two main parts. Six basic types of simple machines exist: the lever, inclined plane, wedge, pulley, screw and the wheel […]

What organisms do humans compete with? Human beings also compete with some animals for food. For example, humans fish the oceans, taking many fish for their own consumption. When they do so, they take fish that larger fish would otherwise have eaten. These are both instances of humans and animals competing for resources. What do […]

What is the main benefit of SSB? The Benefits of SSB By reducing the bandwidth transmitted, you may put double the number of channels (or stations) in the same frequency band. Because the carrier if also filtered out, there is no transmission unless information is being sent. This is useful if you are trying to […]

How heat moves from one solid to another solid? Conduction transfers heat energy in solids. The moving particles of a warm soild material can increase the heat energy of the particles in a cooler solid material by transferring it directly from one particle to the next. Since particles are closer together, solids conduct heat better […]

How does temperature affect viscosity of magma? MAGMA VISCOSITY, TEMPERATURE, AND GAS CONTENT. The effect of temperature on viscosity is intuitive. Like most liquids, the higher the temperature, the more fluid a substance becomes, thus lowering its viscosity. Composition plays an even greater role in determining a magma’s viscosity. What are the factors that affects […]

What is the formula for impulse? An impulse is equal to the net force on the object times the time period over which this force is applied. Below, we derive impulse from the equation F = ma, which comes from Newton’s second law of motion. What type of word is impulse? noun. an impelling force […]

What causes rightward shift in supply curve? Price of the product: When there is an increase in the price of the product and if it is more than the marginal cost of production, it enables the firm to earn excess profit by selling at a higher price. So, there is an increase in the supply […]

What would be a good warm up for golfing? Warming up properly before you stretch or swing a club is pretty easy. You can do something as simple as making a few slow-motion golf swings, taking a brisk walk, or doing a few squats and lunges — anything that gets your heart rate up and […]
