A submarine was situated 450 feet below sea level. If it descends 300 feet. What is its new position?

Ani is scuba diving. She descends 5 feet below sea level. She descends same distance 4 more times. What is Ani's final elevation?

An arch on a road is in the shape of semi-ellipse. The breadth of the road is 30 feet. A man 6 feet tall just touches the arch when he stands 2 feet the side . i. Assuming the road level as x-axis (major axis). Find the point C. ii. What is the maximum height of arch (minor axis)?

A diver having a moment of inertia of 6.0 kg-m^2 about an axis through its centre of mass rotates at an angular speed of 2 rad/s about this axis. If he folds his hands and feet to decrease the moment of inertia to 5.0 kg-m^2 what will be the new angular speed?

Figure shows an equiconvex lens (of refractive index 1.50 ) in contact with a liquid layer on top of a plane mirror. A small needle with its tip on the principal axis is moved along the axis until its inverted image is found at the position of the needle. The distance of the needle from the lens is measured to be 45.0 cm. The liquid is removed and the experiment is repeated . the new distance is measured to be 30.0 cm. What is the refractive index of the liquid ?

An electric field is uniform and in the positive xdirection for positivex and uniform with the same magnitude but in the negative x direction for negative x. It is given that E= 200 hati N//C" for "x gt 0 and E=- 200 hati N//C" for "3 lt 0. A right circular cylinder of length 20 cm and radius 5 cm has its centre at the origin and its axis along the x-axis so that one tace is at x = +10 em and the other is at x=10 cm a. What is the net outward flux through cach flat face? b. What is the flux through the side of the cylinder? c. What is the net outward flux through the cylinder?

Consider the situation shown in figure. Suppose a small electric field E exists in the space in the vertically upward direction and the upper block carries a positive charge Q on its top surface. The friction coefficient between the two blocks is mu but teh floor is smooth. what maximum horizontal force F can be applied without disturbing the equilibrium?
