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? 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 […]

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 […]

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 = […]

How many coordinate systems are there? In this article we mainly discuss two types of coordinate systems. What is the difference between phi and theta? Theta is the same as the angle used in polar coordinates. Phi is the angle between the z-axis and the line connecting the origin and the point. How do you […]

What enzymes do lysosomes contain? Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label. What organelle is responsible for respiration? The “powerhouses” of the […]

Is K or Br bigger? Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms. Does S or O have a larger atomic radius? Consequently for […]

Where in your body do mechanical and chemical digestion occur? Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine. What mechanical and chemical digestion occurs in […]
