What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its perimeter?
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
How does the time period or number of variables effect correlation coefficient?
The time period may not affect the correlation coefficient at all. If looking at the correlation between the mass and volume of steel objects, time is totally irrelevant. The effect of the number of variables depends on whether or not the extra variables are related to ANY of the variables in the equation.
If the standard deviation is doubled what will be the effect on the confidence interval?
The confidence intervals will increase. How much it will increase depends on whether the underlying probability model is additive or multiplicative.
What will effect on the area of triangle if the side of the triangle just double from their original side?
area will get 4 times
Does the coefficient of kinetic friction depend on the weight of the block?
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
Decreasing the surface area in contact with the table will increase the pressure at that contact point. This can lead to an increase in the coefficient of kinetic friction, as the roughness at the microscopic level can become more significant.
What happened to the coefficients of friction as the weight increases?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
What can you conclude about the effect of friction in the pulley on the value of K?
Friction in the pulley will decrease the efficiency of the system, causing an increase in the value of K. This is because some of the input energy is lost to overcoming friction, resulting in a higher value of the kinetic friction coefficient.
Why should cars drive slower in wet weather?
Friction is reduced between the tire and the road.Frictional Force = Coefficient of Friction x WeightThe weight of the car has not changed, however, the coefficient of friction has gone down ultimately reducing the available emergency stopping power of the car.The effect is referred to as Hydroplaning ; see related link .
What can effect the amount of frictions between two objects?
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
What is the effect of force on friction?
The force acting on an object increases the friction between the object and the surface it is on. As the force increases, the friction force also increases proportionally until it reaches a maximum value, called the limiting friction. This relationship is described by the equation: friction force = coefficient of friction * normal force.
What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its perimeter?
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
What was the original salary of the president of the US?
The salary for the President was first set at $25,000 per year. The figure stayed in effect until 1869 when it doubled to $50,000.
What is the effect on the perimeter of a pentagon if the dimension are doubled?
Since the perimeter is a linear measure it is also doubled.
