Which quantity is the rate at which velocity changes?
Acceleration
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
What is meant by negative gradient of a quantity?
The gradient of a quantity is the greatest rate at which it changes as you move in different directions from where you are now. If the quantity has a negative gradient, that means that the quantity decreases in that direction. A great example of a negative gradient is the elevation of the land at a point on a road that has a hill on one side and a cliff on the other side. The greatest rate at which the elevation changes is in the direction off the edge of the cliff, and it's negative in that direction.
What is the integral of mod x function?
The integral of the absolute value function, |x|, is given by the piecewise function ∫|x|dx = (x^2)/2 + C for x ≥ 0 and ∫|x|dx = (-x^2)/2 + C for x < 0, where C is the constant of integration. This is because the absolute value function changes its behavior at x = 0, resulting in two different expressions for the integral depending on the sign of x.
Why is it important to add the constant of integration immediately when the integration is performed?
When you do an integration, you are (implicitly or explicitly) recognizing that what you are integrating is a "rate of change". Your integration over a particular interval provides you with the answer to the question "what is the total change over this interval?". To get the total value of this quantity you must add the initial amount or value. That is represented by the constant of integration. When you integrate between specific limits and you are asking the question "how much is the total change" the initial value is not needed, and in fact does not appear when you insert the initial and final values of the variable over which you are integrating. So you must distinguish between finding the total change, or finding the final value. Re-reading this, I could have been a bit clearer. I'll give an example. Suppose something is accelerating at a constant acceleration designated by "a". Between the times t1 and t2 the velocity changes by a(t2-t1) which you get by integrating "a" and applying the limits t2 and t1. But the change in velocity is not the same as the velocity itself, which is equal to the initial velocity, "vo", plus the change in velocity a(t2-t1). This shows that the integral between limits just gives the accumulated change. but if you want the final VALUE, you have to add on the initial value. You might see a statement like "the integral of a with respect to time, when a is constant is vo + at ". You can check this by differentiating with respect to t, and you find the constant vo disappears. In summary, the integral evaluated by simply applying the limits gives the accumulated change, but to get the final value you have to add on the pre-existing value, and in this context the pre-existing value also carries the name of "constant of integration".
Name the quantity that essentially changes when a body moves?
A moving body can be broken into the factors of mass and velocity. Momentum is the quantity that changes as velocity increases or decreases, assuming mass is held constant.
Can you have constant speed but change in velocity?
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
Name the physical quantity which remains changes during circular motion?
The speed of an object in circular motion remains constant while the direction of the velocity changes continuously.
What is the difference between constants and variables?
A variable is a quantity which changes its value through out the program or its lifetime. But a constant is a quantity which does not change its value through out its life time. There are 5 basic constants.
What is The rate of a changing quantity is the amount it changes per single increment of time?
The rate of a changing quantity is the derivative of that quantity with respect to time. It represents how fast the quantity is changing at a specific point in time. This rate can be constant or variable depending on the nature of the change.
What is the derivative of just a constant?
0 A derivative is the rate of change of a function as another variable changes. As there is no change to a constant, the derivative is necessarily 0.
What is temperature co-efficiant?
It means how much some quantity (for example, electrical resistance) changes as a function of temperature.
What is temperature co-efficient?
It means how much some quantity (for example, electrical resistance) changes as a function of temperature.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
What is alternating quantity?
An alternating quantity is a type of electrical current or voltage that periodically changes direction, moving back and forth. It is commonly represented as a sinusoidal waveform that alternates between positive and negative values. This type of electricity is used in household appliances and is generated by power plants.
How can one calculate the elasticity of demand from a demand function?
To calculate the elasticity of demand from a demand function, you can use the formula: elasticity of demand ( change in quantity demanded) / ( change in price). This formula helps determine how responsive the quantity demanded is to changes in price.
How does the mathematical relationship in Boyle's law compare to that in Charles' law?
Boyle's law states that pressure is inversely proportional to volume at constant temperature, represented by P1V1 = P2V2. Charles' law states that volume is directly proportional to temperature at constant pressure, represented by V1/T1 = V2/T2. Both laws show how one variable changes in response to changes in another variable while keeping another variable constant.
