What is tertiary motion? Tertiary motion is sequence motion. It is determined by the specific use oi one or several ofthese transition devices: the cut, the jump cut, the dissolve, the wipe, the fade, and special transitional effects. The cut is an instantaneous change from one image to another. What are the primary motions? For […]
What is the pH level of a banana?
What does high or low specific heat capacity mean?
What does high or low specific heat capacity mean? A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature (water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low […]
What best compares radiation and conduction?
What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]
Which planet has the greatest eccentricity?
Which planet has the greatest eccentricity? Mercury How is Earth’s eccentricity calculated? The formula to determine the eccentricity of an ellipse is the distance between foci divided by the length of the major axis. What is the maximum allowed value for eccentricity? 0.057 Is Earth’s orbital eccentricity large or small? The eccentricity of Earth’s orbit […]
Can the velocity of a particle change even if its speed is constant give examples?
Can the velocity of a particle change even if its speed is constant give examples? Give example. Yes. Even though its speed is constant, if it is not traveling in a straight line, the velocity can vary. Can an object have zero velocity but non zero acceleration? Acceleration is the change in velocity, not the […]
What products increase friction?
What products increase friction? There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction […]
What is the highest on Richter scale?
What is the highest on Richter scale? In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.). Where is the […]
Why are seawalls bad for beaches?
Why are seawalls bad for beaches? They’ve been shown to disrupt the natural pattern of beach replenishment along the coast. Seawalls also speed up erosion on bluffs, putting adjacent ocean-front property at risk. According to the California Coastal Commission, about a third of Southern California beaches are armored with seawalls. How long does it take […]
