Can a coefficient of friction be equal to zero?
No , coefficient of friction can not be zero. if it is zero then there will be no frictional force between two bodies.And in our universe these types of object didnot exit.
Why the coefficient of friction cannot be zero?
The coefficient of friction is an empirical measurement and has to be measured experimentally, and cannot be found through calculations. Rougher surfaces tend to have higher effective values. Most dry materials in combination have friction coefficient values between 0.3 and 0.6. Values outside this range are rarer, but Teflon, for example, can have a coefficient as low as 0.04. Therefore, a value of zero would mean no friction at all, an ELUSIVE property even magnetic levitation vehicles have drag.
Which material has nearly zero temperature coefficient?
nickel Constantly
What is the lowest coefficient to friction?
It can never be exactly zero, but it is close to 0.
How do the resistance and the weight of a falling object compare when terminal speed is reached?
Air resistance doesn't change with weight. It changes with speed and shape. More speed, more air resistance. If the shape has a lot of surface are to drag the air, it is more resistant, but this factor does not change with weight or speed. This is why terminal velocity is possible. As the object falls, its speed increases, so its resistance increases also, because resistance depends directly on speed. But as this resistance is increasing, the gravity is staying the same. So, eventually, resistance catches up with gravity and cancels it out, causing an end to acceleration, or constant speed.
What is the zero lift drag coefficient of Airbus A330-200?
coefficient of drag in 0 lift
What is zero lift coefficient of drag?
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
What is the zero lift drag coefficient of airbus A380?
0.032
What is the value of zero lift drag in Airbus a380?
17.4
A correlation coefficient of zero indicates?
A correlation coefficient of zero means that two things are not correlated to each other.
Is it possible for a coefficient of variation of a set of data to be zero Explain.?
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
Can a coefficient of friction be equal to zero?
No , coefficient of friction can not be zero. if it is zero then there will be no frictional force between two bodies.And in our universe these types of object didnot exit.
If coefficient of skewness equals 0 then what would you say about the skewness of the distribution?
if coefficient of skewness is zero then distribution is symmetric or zero skewed.

What does a correlation coefficient of zero indicates?
A coefficient of zero means there is no correlation between two variables. A coefficient of -1 indicates strong negative correlation, while +1 suggests strong positive correlation.
When is the correlation coefficient zero?
when there is no relation between the variables
What is the temperature coefficient of an extrinsic semiconductor is?
positive
