What are the 3 equations for power? Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = […]
Which describes the movement of cells?
Which describes the movement of cells? Cell movement or motility is a highly dynamic phenomenon that is essential to a variety of biological processes such as the development of an organism (morphogenesis), wound healing, cancer metastasis and immune response. In all these examples, cells reach their target by crawling. What describes simple diffusion? In biology, […]

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 […]
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 […]

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 […]
