Answer:
The best way to approach this type of problem is to use the "complement method" ...
P(positive result) = 1 - P(negative result)
= 1 - (1 - 0.03)^3
= 1 - 0.97^3 = 0.087327 or 8.7%
Explanation:
The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
Answer:
The observation that could be made in regards a neon light placed in one evacuated (airless) chambea r, and battery powered radio placed in a second evacuated chamber, switched on at the same time by remote control, is that they are managed as capacitors.
Explanation:
Capacitors, also known as condensers, store energy and, we can also see them in the sky, they are the clouds.
Capacitors are made of two electrical conductors, separated by an insulator, when you add electrical energy to a capacitor you are charging a capacitor, the opposite is known as discharging.
Answer:
The definition of energy is the ability to do work.
One way to think abnout is whenever you have a lto of eneergy you can do a lot of work, but with little energy you can't do much work.
