Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
Do convex lenses have negative focal length?
No, convex lenses have positive focal lengths. The focal length is the distance from the lens to its focal point where light rays converge. In convex lenses, parallel light rays are focused to a point on the opposite side of the lens, resulting in a positive focal length.
Why is concave lens called a negative lens?
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
Can the magnitude of a vector have a negative value and why?
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.
How do you tell the difference between positive and negative on a led?
The longer leg of an LED is typically the positive (+) terminal, while the shorter leg is the negative (-) terminal. Additionally, the positive leg usually has a flat edge or a notch near it as a visual indicator.
Is the number of visitors at an amusement park and the length of the lines for the rides a positive or negative correlation?
positive
Why are most cars negative ground?
any any one positive or negative has to be grounded to reduce wire length , normally -ve is chosen as ground any any one positive or negative has to be grounded to reduce wire length , normally -ve is chosen as ground
Can a body have negative speedwhy?
No. The speed is the length of the velocity vector, and that is always zero or positive.
Can the sides of a rectangle be negative numbers and therefore have a positive area?
No. Measurement of length of rectangle sides is always a positive number in Euclidean geometry.
How do you find the x and y intercept of a negative number?
A number, negative or positive, does not have intercepts. It also does not have time, mass, length, width or political affiliation.
What is a calibrated focal length?
A calibrated focal length is an adjusted value of the equivalent focal length on a camera, so as to equalize the positive and negative values of distortion over a field.
On a LED which leg is longer - positive or negative?
L.E.D has one leg longer then the other one, the longer one is positive and the smaller one is negative. If you have a l.e.d which has same length of legs then look inside the l.e.d for two kind of triangle peices and one of them will be smaller which is positive and one which is bigger and is negative.
How can you identify the different legs of a led?
The length of the legs. The positive leg is always longer than the negative one.
Can the area of a square be negative?
not in the real world. The area of a square = The length of a side, squared. Any number squared is positive.
What LOA means?
LOA stands for Law of Attraction, a concept that suggests positive or negative thoughts bring positive or negative experiences into a person's life. It implies that individuals can attract desired outcomes by focusing on them and maintaining a positive mindset.
Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
Do horizontal lines always have a slope of zero?
Yes. There is no positive or negative rise to generate a slope, and it cannot have a run of zero length.
