Which powder detergents work better on grass stains gain or tide?
,bnhn, v j, b
Is mixing for mud and water is a physical change and why?
yes b
What substance would change least in temperature A water B cold Jello C ice cube frozen solid D frozen ice shavings?
water
When bonds between atoms are broken or formed is the outcome A a physical change B an element increasing in size C a chemical change D a change of state?
B. an element increasing in size Resources: Myself 6 years In College
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
How does a system that is in balance is said to have what?
B. stability
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.
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.

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
Heat will flow from a hot object to a cold object until the objects reach A. stability. B. equilibrium. C. collapse. D. boiling point?
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

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.
