Explain how an intrinsic semiconductor convert into p type and n type semiconductor​

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass
