What does a horizontal line indicate? A horizontal line is commonly used in technical analysis to mark areas of support or resistance. A horizontal line runs parallel to the x-axis. In technical analysis, the horizontal line is typically drawn along a swing high, or a series of them, where each high in the series stopped […]
Why is a car crash inelastic?
Why is a car crash inelastic? Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision. What happens in […]
Is chromatin made of nucleosomes?
Is chromatin made of nucleosomes? Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones. What are […]
What is the cycle of rain called?
What is the cycle of rain called? As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. This process is called condensation. When a cloud becomes full of liquid water, it falls from the sky as rain or snow—also […]

The most famous star in the Little Dipper is Polaris, which is currently known as the North Star or Pole Star, as it appears to be aligned with Earth’s axis, or Celestial Pole. How do you identify Ursa […]
What is the relationship between the mass of the counterweight and theamount of work done on the projectile?
What is the relationship between the mass of the counterweight and theamount of work done on the projectile? As the force exerted on the projectile is equal to the mass of the counterweight times the gravitational constant, when the mass is increased, the force will also increase. What forces are involved in a trebuchet? A […]
Where is a magnetic field the weakest?
Where is a magnetic field the weakest? equator What makes a magnet stronger or weaker? Most substances have an equal number of electrons spinning in opposite directions, which cancels out their magnetism. These substances have high magnetic permeability and make the strongest magnets. Iron, cobalt and nickel are among these substances. Neodymium iron boron (NdFeb) […]
How do you set up dimensional analysis problems?
How do you set up dimensional analysis problems? Set up each problem by writing down what you need to find with a question mark. Then set it equal to the information that you are given. The problem is solved by multiplying the given data and its units by the appropriate unit factors so that only […]
