Two objects, one with a mass of 2 kg and one with a mass of 3 kg are attracted to each other by a gravitational force. if the force on one mass is 4 n, what is the force on the other mass?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

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

Explain the difference in reactivity of the elements based on their electron configurations.
