We must apply a force of magnitude 83 n to hold the block stationary at x = −2.0 cm. from that position we then slowly move the block so that our force does +4.8 j of work on the spring-block system; the block is then again stationary. what is the block's position x? (there are two answers.)
electricity is a term used to describe the energy produced when electrons are caused to directional flow from atom to atom. this movement of electrons between atoms is called electrical current.
recall the equation relating an object's change in thermal energy to its change in temperature:
δq = mcδt
δq is the change in thermal energy.
m is the mass of the object.
c is the object's specific heat.
δt is the object's change in temperature.
m = 0.5 kg = 500g
δt = (7-0)⁰c = 7°c
online sources say the specific heat of silver is 0.240 j/g⁰c
substitute the terms in the equation with the given values and solve for δq:
δq = 500×0.240×7δq = 840 j

the sociological perspective approaches that sociologists have toward analyzing sociological phenomena. the main perspectives are symbolic interactionism, conflict theory and functionalism. teenage moms have a much higher likelihood of dropping out of high school than their peers.
