A concave lens produces a virtual image with a negative magnification. This means that the image is smaller than the actual object and appears on the same side as the object.
The magnification can be calculated using the magnification formula: M = -f / (f - d), where f is the focal length and d is the object distance. In this case, f = 10 cm and d = 40 cm. Plugging in these values gives M = -10 / (10 - 40) = -10 / -30 = 1/3. Therefore, the magnification is 1/3.
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.
Oil is considered to be concave when placed between two surfaces, such as in a meniscus. This is due to oil having cohesive forces that cause the liquid to curve downward between the surfaces.
An electron acquires a negative charge by having an excess of negatively charged particles called electrons. In the context of atomic structure, the negative charge of an electron is significant because it balances the positive charge of protons in the nucleus, creating a stable atom. This balance of positive and negative charges allows atoms to form bonds with other atoms and participate in chemical reactions.
The Hounsfield unit of water is 0. It serves as the reference point in Hounsfield units, with densities higher than water having positive values and lower densities having negative values.
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
No. If they were then there would be no point in having a negative.
Positive x Positive = Positive Negative x Negative = Positive Positive x Negative = Negative Basically if the signs are the same, the answer will always be positive, and if the signs are different the answer will be negative. Hope this helps.
Positive
The charge is 0 if the positive and negative charges were equal
If an altitude above sea level is positive, then an altitude below sea level is negative.If having money is positive, having a debt is negative.If gaining money is positive, losing money is negative (a negative gain).If an increase in speed is a positive acceleration, a decrease in speed is a negative acceleration.Any other similar case, where you define one thing as positive, and its opposite as negative.
Criticism is having a comment for something and delivering it, whether in a positive or completely negative way. Criticism is having a comment for something and delivering it, whether in a positive or completely negative way.
yes. if you are having acute hepatitis with Australia antigen positive it can later become negative.
Yes, if you interpret some of the exterior angles as having negative measure.
just put true
A piece of photographic film having the negative (opposite) image of your positive print or image.
Most people would consider it having a negative effect
