The correct Answer is:
To solve the question, we need to analyze the three statements provided and identify the common answer for all of them. ### Step-by-Step Solution: 1. **Identify the Cambium that Produces Cork**: - The cambium responsible for producing cork is known as **phallogen**. This layer is also referred to as cork cambium. It is responsible for the formation of the outer protective layer of the plant. 2. **Identify the Source of Common Bottle Cork**: - The common bottle cork is derived from the bark of the **Quercus suber** (cork oak) tree. The cork produced from the phallogen of this tree is what is used for making bottle corks. 3. **Identify the Meristem Parallel to the Longitudinal Axis**: - The meristem that runs parallel to the longitudinal axis of the plant is also known as **phallogen**. This is because it contributes to the growth of the plant in a longitudinal direction, forming the periderm. 4. **Conclusion**: - All three statements point to the same answer, which is **phallogen**. Thus, the answer to the question is **phallogen**.

A particle of mass 0.1kg is launched at an angle of 53^(@) with the horizontal . The particle enters a fixed rough hollow tube whose length is slightly less than 12.5m and which is inclined at an angle of 37^(@) with the horizontal as shown in figure. It is known that the velocity of ball when it enters the tube is parallel to the axis of the tube. The coefficient of friction betweent the particle and tube inside the tube is mu=(3)/(8)[ Take g=10m//g^(2)] The velocity of the particle as it enters the tube is :

The Betatron was the first important machine for producing high energy electrons. The action of the betatron depends on the same fundamental principle as that of the transformer in which an alternating current applied to a primary coil induces an altermating current usually with higher or lower voltage in the secondary coil. In the betatron secondary coil is replaced by a doughnut shaped vacuum chamber.Electron produced in the doughnut from a hot filament, are given a preliminary acceleration by the application of an electric field having potential difference of 20 kV to 70 kV , when an alternating magnetic field is applied parallel to the axis of the tube, two effects are produced (1) an electromotive force is produced in the electron orbit by the changing magnetic flux that gives an additional energy to the electrons (2) a radial force is produced by the action of magnetic field whose direction is perpendicular to the electron velocity. Which keeps the electron moving in a circular path. Conditions are arranged such that the increasing magnetic field keeps the electron in a circular orbit of constant radius. The mathematical relation between the betatron parameters to ensure the above condition is called BETATRON condition. If the orbit radius of the circular path traced by the electron is R , magnetic field is B , speed of the electron is v , mass of the electron is m , charge on the electron is e and phi is the flux within the orbit of radius R . Then answer the following questions based on the above comprehension. What is the tangential force acting on the electron ?
