Two negatives equal what?
It is said that two negatives equal a positive when multiplying them with coefficients.
What does Two Kinds refer to?
Two kinds of daughters: obedient and disobedient
What is the key to using the elimination method to find variable terms in the two equations that have equal or opposite coefficients?
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
What is a ratio that compares two quantities with different kinds of units?
A rate.
What is the difference between irrational and transcendental numbers?
An irrational number is a number that cannot be represented as a fraction involving two integers. A transcendental number is a number that cannot be repesented as a polynomial with rational coefficients. Two notable transcendental numbers are pi and e.
What are the two kinds of coefficients?
In terms of mathematics, a coefficient plays the role of a multiplicative factor in a series or an expression. The two different kinds of coefficients include numbers and letters.
Why are coefficients of friction unitl-ess values?
Coefficients of friction are unitless values because they represent the ratio between the force necessary to overcome friction and the force pressing two surfaces together. Since the units cancel out in this ratio, coefficients of friction are expressed as pure numbers without units.
What 2 surfaces would have the highest coefficient or friction?
Two surfaces with high coefficients of friction are rubber on concrete and sandpaper on wood. These surfaces have rough textures that increase friction and resistance to sliding.
What are two examples of two surfaces that have a low coefficient of friction?
Ice and glass both have very low coefficients of friction because they are very smooth, so it is easier for a substance to glide over them.
Riction between two flat surfaces can be divided into two categories What are the two most common kinds of friction?
The two most common kinds of friction are static friction, which occurs when an object is at rest and resists being moved, and kinetic friction, which occurs when an object is in motion and resists being accelerated or decelerated.
Which two surfaces would have the highest cofficient of friction?
Two rough surfaces with high friction coefficients would have the highest coefficient of friction. For example, rubber on concrete or sandpaper on wood would typically result in a high coefficient of friction due to the roughness of the surfaces.
How can you increase the magnitude of friction between two surfaces How can you decrease the magnitude of friction?
To increase friction, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or use materials with higher coefficients of friction. To decrease friction, you can use lubricants to reduce surface roughness and create a barrier between the surfaces, reduce the normal force acting on the surfaces, or use materials with lower coefficients of friction.
When two surfaces would have the highest coefficient or friction?
The coefficient of friction between two surfaces is highest when the surfaces are rough and have a large amount of resistance to sliding past each other. Smooth surfaces or surfaces with lubricants have lower coefficients of friction.
Which things causes low friction?
Smooth surfaces, lubricants, and reducing the contact area between two objects are factors that can cause low friction. Additionally, using materials with low coefficients of friction such as Teflon can also help reduce friction.
Friction between two flat surfaces can be divided into two categories What are the two most common kinds of friction?
The two most common kinds of friction are static friction, which occurs between stationary objects, and kinetic friction, which occurs between moving objects. Static friction prevents objects from sliding against each other, while kinetic friction resists the motion of sliding objects.
Is the friction is same for all the surfaces?
No, the friction between two surfaces depends on factors such as the roughness of the surfaces, the force pressing them together, and the materials involved. Different surfaces will have different coefficients of friction which determine how much force is required to overcome the friction between them.
What two kinds of friction affecting mouse traps?
