At what point of a projectile motion, acceleration and velocity are perpendicular to each other ?
A cell of constant emf first connected to a resistance $R_1$ and then connected to a resistance $R_2$. If power delivered in both cases is same then the internal resistance of the cell is :
A can is taken out from a refrigerator at $0^{\circ} C$. The atmospheric temperature is $25^{\circ}C$. If $t_1$ is the time taken to heat from $0^{\circ} C$ to $5^{\circ} C$ and $t_2$ is the time taken from $10^{\circ} C$ to $15^{\circ}C$, then :
Angular momentum is conserved :
Initially two gas samples $1$ and $2$ are at the same condition. The volume of the two are halved, one isothermally and the other adiabatically. What is the relation between the final pressure $P_1$ and $ P_2$ ?
