What else can I help you with?
What do electrons have that protons always have in equal magnitude?
Electrons have negative charge and protons have positive charge. These charges always have equal magnitude but opposite signs in an atom, maintaining electrical neutrality.
A star of magnitude plus 8 is?
A star with a magnitude of +8 is "very dim", and not visible in urban or suburban areas. Only in the darkest rural areas, and only for people with EXCELLENT eyes, would a +8 magnitude star be visible.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
What is a good comparison of the charges of an electron and the charges of a proton?
They are equal in magnitude but opposite in charge.
What patterns exist in the law of action reaction?
They are equal in magnitude and act in opposite directions.
What must be the relationship between two vectors a and b if the magnitude of vector a plus b is equal to magnitude of a-b?
a and b must face in opposite directions.
When magnitude of vector a plus b is equal to the magnitude of vector a minus b then what is the angle between two vectors a and b?
2pi/3 radian or equivalent 120 degree
Suppose vector equation A plus B equals 0.how does the magnitude of B compare to that of A?
B could be either greater than, lesser than or equal to A. 7 +(-7) = 0 (-7) = 7 = 0 0 + 0 = 0
If is added to under what conditions does the resultant vector have a magnitude equal to A B?
1. When the two vectors are parlell the magnitude of resultant vector R=A+B. 2. When the two vectors are having equal magnitude and they are antiparlell then R=A-A=0. For more information: thrinath_dadi@yahoo.com
What does b plus a plus b-a equal?
b + a + b - a = 2b
If vector B is added to vector A under what circumstances does the resultant vector A plus B have magnitude A plus B. under what circumstances does the resultant vector equals to zero?
if b + a , since a+b equals b + a due to it being commutative . it shud have the same magnitude and direction
How a plus b is equal to a-b?
If a = 2b
Two vectors A and B have precisely equal magnitude for the magnitude of A - B to be 100 times larger than the the magnitude of what must be the angle between them?

If A plus B equals 0 than what can you say about the components of the two vectors?
The components of these vectors will be equal in magnitude but opposite in direction. This can be proved as follows.If A+B=0 then A=-BOr Axi+Ayj+Azk=-(Bxi+Byj+Bzk)Comparing the co-efficients of i, j, kAx=-Bx Ay=-By Az=-BzThis shows that components of A and B are equal in magnitude to each other but are opposite in direction.
What does a squared plus b squared equal?
(a+b)(a+b)Also equal to a2+2ab+b2
A plus B equals?
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
If a plus b equals c what does a plus c equal?
A+c= 2a+b
