In general relativity, gravitational red shift is caused by

a. the slowing of clocks due to increased gravitational kinetic energy.

b. the slowing of clocks due to increased gravitational potential energy.

c. the slowing of clocks due to lower gravitational kinetic energy.

d. the slowing of clocks due to lower gravitational potential energy.

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?
