What is the critical relationship between cell volume and surface area?
The volume is proportional to the cube of the diameter, but the area, only to the square of the diameter. For example, if you double the diameter, the area will increase by a factor of 4, and the volume, by a factor of 8. Thus, the area/volume ratio will worsen, by a factor of 2.The volume is proportional to the cube of the diameter, but the area, only to the square of the diameter.

How many times longer is the circumference of a circle than its diameter?
It is larger than the diameter by a factor of Pi (about 3.1416).
To cut the maximum likely error in half the sample size should be?
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.
Suppose that each dimension of a prism is increased by ten percent by what percent does its volume increase?
When linear dimensions are increased by a factor of 'N', area increasesby the factor of N2 and volume increases by the factor of N3.(1.10)3 = 1.331 = 33.1% increase
When the height of an object is doubled its gravitational potential energy is increased by a factor of what?
two
If the diameter of an objective mirror is doubled its light-gathering power becomes?
Just like any antenna used to collect electromagnetic energy at any other frequency, the 'gain' is proportional to the antenna's area. Since the area varies as the square of the collector's diameter, doubling the diameter increases the gain by a factor of 22 = 4. The corresponding increase in gain is 6 dB.
For maximum photosynthesis increased light intensity has greater effect than increased leaf surface area?
false Edited answer: In case light is limiting factor in the given situation.

Observing a variable star whose total flux has increased by a factor of 625 By what factor did its temperature change?
increased by 5 is the answer!
When the diameter of a sphere is decreased by 25 percent the what percent does its curved area decreases?
The area is proportional to the square of the diameter. So, if the diameter changes by a factor 0.75, the area changes by a factor of 0.752.
If the volume of a sphere decreases by a factor of 27 what happens to its diameter?
The volume of a sphere is 4/3 pi R3, which shows that volume is proportional to the cube of the linear dimension. Alternatively, the linear dimension is proportional to the cube-root of the volume.If volume decreases by a factor of 27, diameter decreases by a factor of (cube-root of 27) = 3. Diameter becomes 1/3rd the original diameter.
Is force factor good for you?
Force Factor's unique Arginine blend promotes increased nitric oxide production in your body. More nitric oxide means more blood flowing to your muscles, which promotes increased endurance in the gym, stronger pumps, and an overall more effective workout. Force Factor's nutrient delivery system ensures that you will receive maximum recovery and growth from any protein you consume.
What is the force factor?
Force Factor is a nitric oxide, body building supplement. Force Factor's unique Arginine blend promotes increased nitric oxide production in your body. More nitric oxide means more blood flowing to your muscles, which promotes increased endurance in the gym, stronger pumps, and an overall more effective workout. Force Factor's nutrient delivery system ensures that you will receive maximum recovery and growth from any protein you consume.
How can calculate maximum demand load?
maximum demand load can be calculated as: # maximum demand=demand factor * Connected load or by # maximum demand = connected load * Diversity Factor Note: Demand factor and diversity factor are NOT same
Is force factor a steroid?
Force Factor is not a steroid, it's a nitric oxide booster. Force Factor's unique Arginine blend promotes increased nitric oxide production in your body. More nitric oxide means more blood flowing to your muscles, which promotes increased endurance in the gym, stronger pumps, and an overall more effective workout. Force Factor's nutrient delivery system ensures that you will receive maximum recovery and growth from any protein you consume.
What is the scale factor of the sun's diameter to an NBA basketball's diameter?
The Sun is about 1,390,000 kilometers in diameter. The NBA basketball is about 0.238506 meters in diamter. The scale factor is about 1,390,000,000 to 0.238506, or about 5,827,945,628 to 1 or about 5.8 billion to one.
Why you are using capacitive hat in short antennas?
Capacitive hats are used to alter the distribution of the current on a short antenna so that the antenna current is not concentrated near the ground. A whip or short antenna can be modeled as a series of LC circuits in which the capacitance per unit length is highest near the base and the inductance per unit length is highest near the top. A capacitive hat simply adds capacitance to the antenna. It basically makes the antenna seem longer, but maximum current is still at the base.The reason why you'd want to make your short antenna longer, is to obtain the antenna's resonance frequency. The length required to do this is a quarter or a half of the wavelength of the radio wave that it's receiving. At resonance, the electrical resistance of the antenna drastically drops, which effectively increases the Q factor, or quality factor, of the resultant output signal. The term Q factor is simply a measurement of how good the clarity and stability of the output signal is, the higher the better when dealing with radios and televisions.Of course, instead of using a capacitive hat on your antenna, you could always physically lengthen the antenna itself. However, considering that commonly-used radio waves can be up to 10 m (33 ft) long, your antenna would have to be about 8 feet long, which would make using your radio a bit awkward.
