A liquid is filled into a semi eliiptical cross section with a as semi major axis and b as semi minor axis. The rato of surface tension forces on the curved part and the plane part of the tube in vertical position will be

A liquid is contained in a vertical tube of semi-circular cross-section. The angle of contact is zero fig. What is the ratio of the force of surface tension on the curved part and the flat part of the tube?

A liquid is containe in a vertical tube of semicircular cross section figure.The contact angle is zero. The force of surface tension on the curved part and on the flat part are in ratio

The relationship between, the semi-major axis, seimi-minor axis and the distance of the focus from the centre of the ellipse is

A planet of mass m is moving around the sun in an elliptical orbit of semi-major axis a :

Two satellite of equal mass are revolving around earth in elliptical orbits of different semi - major axis . If their angular momenta about earth centre are in the ratio 3 :4 then ratio of their area l velocity is

An elliptical loop having resistance R, of semi major axis a, and semi minor axis b is placed in a magnetic field as shown in the figure. If the loop is rotated about the x-axis with angular frequency omega , the average power loss in the loop due to Joule heating is :

A planet revolves in an elliptical orbit around the sun. The semi-major and minor axes are a and b , then the time period is given by :

If the length of the semi-major axis of an ellipse is 68 and e = 1/2, then the area of the rectangle formed by joining the vertices of latusrecta of the ellipse is equal to

The U -tube shown in the figure has a uniform cross section. A liquid is filled up to heights h_(1) and h_(2) in the two arms and they are allowed to move. Neglecting viscosity and surface tension, find the state of the liquid when the levels equalize in the two arms. Find the correct statement.
