A hanging wire made of an alloy of iron with diameter 0.15 cm is initially 2.8 m long. When a 184 kg mass is hung from it, the wire stretches an amount 1.43 cm. A mole of iron has a mass of 56 grams, and its density is 7.87 g/cm^3. Based on these experimental measurements, what is Young?s modulus for this alloy of iron? As you?ve done before, from the mass of one mole and the density you can find the length of the interatomic bond (diameter of one atom). This is 2.28 X 10^-10 m for iron. As shown in the textbook, the micro quantity (the stiffness of one interatomic bond) can be related to the macro property Y:

An input force of 7 n is applied to a machine with a mechanical advantage of 1.75. what is the maximum the machine could lift? 12.25 n7n7.25 n26.2 n

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

The energy equivalent of the rest mass of an electron is
