AIEEE 2012 PYQ Mock Test

A liquid in a beaker has temperature $\theta (t)$ at time $t$ and ${\theta }_0$ is temperature of surroundings, then according to Newton's law of cooling the correct graph between $\ln (\theta -{\theta }_0)$ and $t$ is:

A particle of mass $m$ is at rest at the origin at time $t=0$. It is subjected to a force $F(t)=F_0{e}^{-bt}$ in the $x$ direction. Its speed $v(t)$ is depicted by which of the following curves?

Two electric bulbs marked $25\text{W}-220\text{V}$ and $100\text{W}-220\text{V}$ are connected in series to a $440\text{V}$ supply. Which of the bulbs will fuse?

Resistance of a given wire is obtained by measuring the current flowing in it and the voltage difference applied across it. If the percentage errors in the measurement of the current and the voltage difference are 3% each, then error in the value of resistance of the wire is:

A boy can throw a stone up to a maximum height of $10\text{m}$. The maximum horizontal distance that the boy can throw the same stone up to will be:
