How the tension can be greater than gravity yet the elevator is moving downwards?
The extra tension depends not on the velocity of the elevator, but on its acceleration.
How tension in string is nonconservative force?
No, the force in tension of a string is not conservative. The only non-conservative force acting is the tension force, but it acts perpendicular to the path of the object at every instant, and so it does zero work.
If A 100 kg object is pulled vertically upward 5.0 m by a rope with an acceleration of 1.0 ms2 Find the work done by the tension force in the rope?
Tension in the rope needed to pull the object of mass 100 kg with an acceleration of 1 m/s^2 is 100 N. Since the force is the product of mass and acceleration. So 100 x 1.0 = 100 NWith this force of 100 N the body is moved through a distance of 5.0 m and hence work done will be 500 joule. Since the formula for the work done is F s cos @Here F = 100 N ; s = 5.0 m ; @ = 0 as tension and the displacement in the same direction. Hence the value of work done is 500 joule.
How do you calculate tension of hanging object?
If the object hangs from a weightless string or thread, the tension in the thread is equal to the weight of the object. If there is weight distributed all the way from the ceiling to the bottom of whatever is hanging, then the tension at every point is equal to the weight of everything below that point.
How much tension must a rope withstand if it is used to accelerate a 1600 car vertically upward at 0.70?
F=m*(g+a)=1600*(9.8+.7)=16800N
What is the relation between surface tension and acceleration?
i think that acceleration is directly proportional to surface tension.....
How the tension can be greater than gravity yet the elevator is moving downwards?
The extra tension depends not on the velocity of the elevator, but on its acceleration.
What is the magnitude of the tension in the cord?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.

Will tension on both sides of a string be always equal no matter what acceleration do they have and what mass are connected?
Yes

Calculate tension in the string when both bodies hang vertically when m1 is 4kg and m2 is 5kg?
if the angle is 90 degrees, 5 x 9,8 = T

How does surface tension depend on surface area?
I think its depends on the nature of the liquid, the surrounding environment like (Gravitational acceleration ) and temperature
Object mass40kg is suspended by light string from ceiling of lift of mass200kgThe string breaks if suffers a tension700NFind greatest tension the lift cable if string's intactAns equals4200N n 440N Y?
For simplicity let us assume the acceleration due to gravity to be 10 m/s2 The max force on the string is be 700 N. ie with mass of 40 kg, the acceleration max has be 700/40 ie 35/2 m/s2 The g value is 10 so the excess acceleration that is getting added is 35/2 -10 ie 15/2 m/s2. This acceleration is due to the acceleration of the ascending lift. Hence the tension on the lift cable will be got by the product of the mass of the lift and its acceleration. So it comes to be 1500 N. Already a tension which equals to the weight of the lift namely 2000 N is there. Hence the total tension becomes 3500N. I can't understand why the ans seems equal to 4200 N and 440 N as you have mentioned in the problem.
