At constant pressure,the volume of a fixed mass of a gas varies as a function of temperature as shown in the graph. The volume of the gas at $300^{\circ}C$ is larger than that at $0^{\circ}C$ by a factor of:

Which kingdom consists of organisms that are multicellular,aquatic or terrestrial,heterotrophic,and eukaryotic?

$A$ lead bullet of mass $10 \ g$ travelling at $300 \ m/s$ strikes against a block of wood and comes to rest. Assuming $50\%$ of heat is absorbed by the bullet,the increase in its temperature is (Specific heat of lead $= 150 \ J/kg \cdot ^{\circ}C$) (in $^{\circ}C$)

If $\alpha$ is a non-real root of the equation $x^6-1=0$,then $\frac{\alpha^2+\alpha^3+\alpha^4+\alpha^5}{\alpha+1}$ is equal to

In space, the equation $by + cz + d = 0$ represents a plane perpendicular to the

Velocity and acceleration vectors of a charged particle moving perpendicular to the direction of a magnetic field at a given instant of time are $\overrightarrow{v}=2 \hat{i}+c \hat{j}$ and $\overrightarrow{a}=3 \hat{i}+4 \hat{j}$ respectively. Then the value of $c$ is
