What else can I help you with?
What difference would you expect to see in the bicarbonate indicator in beakers A and B if beaker A had pumped air and beaker B had blown air in it?
well beaker b will have carbon in it as air is breathed in from the mouth, so the indicator will turn yellow! but on the other hand as the beaker A has pumped air in it there is no trace of carbon, so the indicator will turn red!
What substance would change least in temperature A water B cold Jello C ice cube frozen solid D frozen ice shavings?
Water would change least in temperature because it has a high specific heat capacity, which means it can absorb and retain heat well without a large change in temperature. Cold Jello, ice cubes, and frozen ice shavings would all change temperature more readily compared to water.
Atom A has 17 negative electrons atom B has 18 Atom C has 14 and atom D has 11 Which one would be most likely to lose an electron and gain a positive one?
B WRONG in my opinion New Answer D which has 11 electrons and thus is most likely to lose 1 to get to a noble gas electron configuration. Losing 1 electron it would gain a charge of + 1. Look on the periodic table. Na (sodium) has 11 electrons. You can see it only needs to lose 1 and only 1 to gain noble gas configuration and thus have full outer electron shell. THus it would be easiest for it to lose an electron. Thus Na is the answer. Thus the one with 11 electrons is the answer. THus D is the Answer
What is the pronunciation rebus of boron?
The pronunciation rebus of boron would be "B + Oar + On" (B + sound of rowing oar + on).
Which powder detergents work better on grass stains gain or tide?
Both Gain and Tide are effective in removing grass stains, but Tide is known for its powerful stain-fighting capabilities. Tide contains more stain-fighting enzymes and surfactants compared to Gain, making it a better choice for tough stains like grass.
Can you describe how a negative feedback system works?
A negative F/B applies as applied to electronics systems meas that a portion of the output signal will be fed back to stabilize the system. It must be negative in nature so as to control the stability of the loop. If positive F/B is fed back then an uncontrollable situation will occurs whereby the system will oscillate uncontrollably As a rule the more negative F/B is applied the more stable the system. Also as a rule the more F/B the less gain is available to do work. So there is a trade off as stability increased the overall gain decreases.
How does a system that is in balance is said to have what?
B. stability
A equals 1 and B equals 100 increase A by 1 and decrease B by 1 at which number they meet?
They do not. At the start, A+B = 101 is odd After every change, A+B remains odd. If there was a point where A=B then A+B would be 2A (or 2B) which would be even.
A change-of-address form would include a request for your?
B. last address
Which is a characteristic of an ecosystem in approximate equilibrium A. The kinds of organisms do not change. B. Biotic factors do not change. C. Abiotic factors do not change. D. The total number of?
The total number of organisms don't change. which would be D :)
What is the difference between finite open loop gain and closed loop gain?
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
Does addition and subtraction of vectors obey the commutative law?
Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does.

If you take in more calories than you burn you will A. gain weight B. lose weight C. maintain your weight D. decrease your B M I .?
You will gain weight.
What is b - 9b simplified?
What I would do is change the problem up. Instead of b-9b I would make it -(9b-b). It is still the same problem; you will multiply the number inside the parenthesis be -1. So start with 9b-b. That would equal 8b. So it would change from -(9b-b) to -(8b) so you multiply 8b by negative 1 (-1) to get the answer -8b. -8b is your answer. So b - 9b = -8b
After birth B cells change to immature B cells in?
After birth B cells change to immature B cells in follicular B lymphocytes.
What are the types of static stability?
Stability implies an equilibrium which we can both observe and measure. Static stability and dynamic stability centers around no movement vs movement. A simple example of static stability will be a cone or cylindrical object lying on a flat surface. Unless disturbed it stays in the equilibrium state. When disturbed the object tries to come back to its static equilibrium position. An example of dynamic stability will be a chemical equilibrium between two substances A and B in a chemical reaction.The relative rates of the conversion of A to B and B to A establishes an observable overall equilibrium constant for these two chemical species under the specified experimental conditions such as temperature, pressure, etc. Another example would be the revolution of the earth and planets around the sun.
