The piano wire 0.5 metre long has a total mass of 0.01 kg and in strectched at the tension of 800 Newton. calculate the frequency of the wire when it sound its fundamental note

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
