A hollow conducting sphere has an internal radius of r1 = 1. 9 cm and an external radius of r2 = 3. 1 cm. The sphere has a net charge of Q = 1. 9 nC. a) What is the magnitude of the electric field in the cavity at the center of the sphere, in newtons per coulomb?

b) What is the magnitude of the field, in newtons per coulomb, inside the conductor, when r1 < r < r2?

c) What is the magnitude of the field, in newtons per coulomb, at a distance r = 5. 9 m away from the center of the sphere?

What type of nuclear decay causes the atomic number of an element to increase by 1?

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

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.
