Can the moon crash into Earth? The Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. Theory dictates they’ll eventually rain down onto Earth’s surface. What would happen if the moon fell? If the Moon did escape from Earth, […]
Where should the receiver be placed to maximize reception?
Where should the receiver be placed to maximize reception? The receiver of the satellite dish is placed at the focus of the parabola, to maximize signal reception. How many inches should the receiver be located from the vertex for optimal reception? 10.126 inches How do you measure the depth of a parabolic dish? Step 1: […]
What are the major components of a projectile motion?
What are the major components of a projectile motion? There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately. What is the vertical component of the velocity just before […]
Which principle is used in rocket?
Which principle is used in rocket? The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses is explained by the same physical principle—Newton’s third law of motion. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. Another common example is the recoil of a […]
What is the smallest unit of the universe?
What is the smallest unit of the universe? The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across. What is the farthest from Earth? Real-time distance and velocity data is provided by NASA and JPL. At a distance of 152.6 AU (22.8 billion km; 14.2 billion […]
How do you represent elevation?
How do you represent elevation? Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface. How do […]
What is the atomic mass of Mg2+?
What are the factors that affects air pressure?
What are the factors that affects air pressure? Discuss the factors affecting atmospheric pressure with respect to the following: Temperature Altitude Rotation of the Earth Temperature. Altitude. Rotation of the Earth. What are examples of external factors? External factors political – For example, new legislation. economic – For example, inflation and unemployment. social – Changes […]
Which correlation is the weakest?
Which correlation is the weakest? Strength – The weakest linear relationship is indicated by a correlation coefficient equal to 0 (actually this represents no correlation!). The strongest linear correlation is indicated by a correlation of -1 or 1. What is considered a low correlation? Moderate degree: If the value lies between ± 0.30 and ± […]
What is the purpose of dark matter?
What is the purpose of dark matter? [+] Dark matter is the most mysterious, non-interacting substance in the Universe. Its gravitational effects are necessary to explain the rotation of galaxies, the motions of clusters, and the largest scale-structure in the entire Universe. Can we see dark matter? Although we cannot see dark matter and we […]
