Let f(x)=3x4+3x3−12x2+a.f(x) assumes maximum or minimum value according as f′(x) changes its sign from +ve to −ve to +ve. Then.
Rh –ve person donated blood to Rh +ve person for the second time. Then,?
What sign (+ve or -ve) has been given to the following on the basis of Cartesian Sign Convention ? (a) Height of a real image. (b) Height of a virtual image.
If AB is the object and CD is the image formed. If AP is the object distance and CP is the image distance from the mirror. Then choose the correct sign convention? 1. height of image=+ ve2. height of image=−ve3. height of object=+ve4. height of object=−ve5. AP=+ve6. AP=−ve7. PC=+ve8. PC=−ve
A gas is expanded from volume V0 to 2V0 under three different processes, as shown in the figure. Process 1 is isobaric process, process 2 is isothermal and process 3 is adiabatic. Let ΔU1,ΔU2 and ΔU3 be the change in the internal energy of the gas in these three processes, then:
