What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
What does negative sign if the value of magnification of a mirror indicate?
It means that the pre-image and image are on opposite sides of the centre of magnification.
Can the vector product of two vectors be negative?
no .....the scalar product of two vectors never be negative Yes it can If A is a vector, and B = -A, then A.B = -A2 which is negative. Always negative when the angle is between the vectors is obtuse.
Which are the positive and negative?
The ones with the + sign are positive. The ones with the - sign are negative.
When you multiply a negative by a positive what sign do you get?
You get a negative.
What negative correlation indicate?
the negative sign on correlation just means that the slope of the Least Squares Regression Line is negative.
What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
What equation is used to indicate the exothermic reaction?
An exothermic reaction is typically indicated by a negative sign in front of the enthalpy change (∆H) in the reaction equation. This negative sign signifies that heat is released to the surroundings during the reaction.
What does negative sign if the value of magnification of a mirror indicate?
It means that the pre-image and image are on opposite sides of the centre of magnification.
When is a minus sign used in acceleration and deceleration formulas?
A minus sign is used in acceleration and deceleration formulas to indicate direction. If the acceleration is in the opposite direction of the motion, a negative sign is used. For deceleration, which is a form of acceleration that opposes the motion, a negative sign is also used to show the decrease in velocity.
Does the negative sign come before or after the dollar sign?
Does the negative sign come before or after the dollar sign?The negative sign comes before the dollar sign.
Can the vector product of two vectors be negative?
no .....the scalar product of two vectors never be negative Yes it can If A is a vector, and B = -A, then A.B = -A2 which is negative. Always negative when the angle is between the vectors is obtuse.
When heat flows into the system the sign of heat is negative?
No, when heat flows into a system, it is considered positive. Positive heat indicates heat is being added to the system, increasing its internal energy. Negative sign would indicate heat is being lost or leaving the system.
Why is negative sign associated with virtual image?
A negative sign is associated with a virtual image because the light rays do not actually converge at the location of the virtual image. Instead, they appear to diverge from a point behind the mirror or lens, creating the virtual image. Mathematically, this distance is represented as negative to indicate the direction of the virtual image.
Diego is working on a problem about net forces in it meredith is applying a force of 5 n lanaya is applying a force of -7 n Diego writes that meredith is applying a greater force than lanaya expl?
The negative sign does not indicate that the force is actually negative, it is still a positive force that happens to be in the opposite direction to what we have arbitrarily decided to call the positive direction. The magnitude is therefore independent of the sign. Seven is larger than five.
What is an example of negative kinesics?
An example of negative kinesics is when someone crosses their arms while speaking, which can indicate defensiveness, resistance, or disagreement. This nonverbal behavior can create a barrier in communication and be perceived as a sign of disinterest or discomfort.
Which are the positive and negative?
The ones with the + sign are positive. The ones with the - sign are negative.
