An aircraft is moving with a velocity of $300 \mathrm{m}/\mathrm{s}$. If all forces acting on it are balanced, then

A cold soft drink is kept on the balance. When the cap is open, then the weight 

A box of mass $10 \mathrm{kg}$ has a base area of $1 {\mathrm{m}}^2$. Find the pressure exerted by it on the ground.

A metallic block of density $5 \mathrm{g}/{\mathrm{cm}}^3$ and having a dimension of $5 \mathrm{cm}\times 5 \mathrm{cm}\times 5 \mathrm{cm}$ is weighed in water. Its apparent weight will be.

A closed rectangular tank is completely filled with water and is accelerated horizontally with an acceleration in towards right.

Pressure is $\left(\mathrm{i}\right)$ Maximum at and $\left(\mathrm{ii}\right)$ Minimum at

A beaker containing a liquid is kept inside a big closed jar. If the air inside the jar is continuously pumped out, the pressure in the liquid near the bottom of the liquid will

The relative densities of four liquids $P,Q,R$ and $S$ are $1.26, 1.0, 0.84$ and $13.6$ respectively. An object is floated in all these liquids, one by one. In which liquid, the object will float with its maximum volume submerged under the liquid?

State which of the following statement is true.

$\mathrm{A}$ -  A piece of ice floats in water, the level of water remains unchanged when the ice melts completely.

$\mathrm{B}$ -  According to Archimedes' principle the loss in weight of the body in the liquid is equal to the weight of the liquid displaced by the immersed part of the body.
