Where should the weight of a rocket be? In flight, the rocket rotates about the center of gravity, but the direction of the weight force always remains toward the center of the Earth. How does the weight of a rocket affect its flight? With any rocket, and especially with liquid-propellant rockets, weight is an important […]

What happens when a neutral object is brought near a positive object?
What happens when a neutral object is brought near a positive object? Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other. How are charged particles […]

What does potential and kinetic energy have in common? when an object at rest is out into motion. What do potential and kinetic energy have in common? they’re both related to motion. the stored energy of an object due to its position or condition. Where is potential and kinetic energy on a roller coaster? When […]
How is a protein made step by step?
How is a protein made step by step? Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination. Why is the sequence of bases in […]
Is magnetism and electricity the same?
Is magnetism and electricity the same? 3) Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. (This is why physicists usually refer to “electromagnetism” or “electromagnetic” forces together, rather than separately.) How electricity and magnetism […]
Is current split in series?
Is current split in series? The node or junction is the place where conductor splits to form couple parallel branches. When You have resistors in series, there is no such node/junction, the current doesn’t split and flows through each resistor. How does current split in a circuit? The current in a parallel circuit splits into […]

How do you find how many standard deviations from the mean?
How do you find how many standard deviations from the mean? To calculate the standard deviation of those numbers: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result. Then work out the mean of those squared differences. Take the square root of that […]
