Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
What is scaler quantities and vector quantities?
Scalar quantities are physical quantities that have only magnitude, such as mass, temperature, and time. Vector quantities have both magnitude and direction, such as velocity, displacement, and force. Scalars can be added algebraically, while vectors need to consider both magnitude and direction in addition to standard arithmetic operations.
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
Which element can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
Does uranium have positive or negative ions?
Uranium can form both positive and negative ions, depending on the specific chemical conditions. In its most common form, uranium typically forms positive ions by losing electrons to achieve a stable configuration.
Why can velocity be negative but nonzero speed is always positive?
Velocity includes both speed and direction, so a negative velocity indicates motion in the opposite direction. Speed, on the other hand, is a scalar quantity representing the magnitude of velocity without regard to direction, and therefore is always positive.
Can a body have positive distance but negative speed?
First of all you must be familiar with scalar and vector quantities. A scalar quantity is a physical quantity having only magnitude example length. A vector quantity is a physical quantity having both magnitude and directions. Now speed and distance are both scalar quantities which means their values are always positive. But if you considered velocity then there can be a negative value. Velocity is measured w.r.t the direction the object is going. Conventionally the direction is negative if the object is moving to the left of the initial point and positive for the other way.
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
What is a scalar multiplied by a vector?
A scalar multiplied by a vector involves multiplying each component of the vector by the scalar value. This operation scales the vector's magnitude while retaining its direction if the scalar is positive, or reversing its direction if the scalar is negative. The result is a new vector that has the same direction as the original (or the opposite direction if the scalar is negative) but a different magnitude.
Is current a scalar or vector quantity?
It depends upon the condition.But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.
What has both a negative and positive?
An integer has both positive and negative numbers.
Can a scalar be negative?
Scalars can be negative, and so can a change in a scalar value.Take temperature:You can have a temperature of -10 degrees.If temperature falls from 20 to 5 degress, the change was -15 degree.The negative value of the scalar is a consequence of where you take the "zero" to be.With speed you have to be very careful because speed is the scalar bit of velocity. Velocity with no consideration of direction.
Is any quantity having a positive and negative values a vector?
No, not necessarily. A vector is a quantity that has both magnitude and direction. While it can have positive and negative values, not all quantities with positive and negative values represent vectors. Vectors must also obey the rules of vector addition and scalar multiplication.
Why work is negative its is scalar quantity?
A scalar quantity may have positive and negative values - it is simply a real number. But it doesn't have a direction. Think of it as a "vector in one dimension" - whereas the usual vectors have at least 2 dimensions.
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
How can you tell about two integers when their quotient is positive negative zero?
If both integers are positive or both negative then the quotient is positive. If they are one of each then the quotient is negative.
Does wool have a negative or positive charge?
both because every object has both positive and negative charges but mainly has positive charges.
