The correct Answer is:
To solve the question regarding the type of leaf described, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Question**: The question describes a leaf where the midrib (rachis) bears multiple leaflets arranged either alternately or oppositely. 2. **Identifying Leaf Types**: - **Simple Leaf**: A simple leaf has a single blade and does not have leaflets. This option is incorrect. - **Pinnately Compound Leaf**: This type of leaf has a main midrib from which multiple leaflets arise. These leaflets can be arranged alternately or oppositely along the rachis. This option fits the description given in the question. - **Unifoliate Leaf**: A unifoliate leaf has only one leaflet and does not have multiple leaflets arranged in any manner. This option is incorrect. - **Decompound Leaf**: A decompound leaf has leaflets that are further divided into smaller leaflets. While it has multiple leaflets, it does not match the description of being arranged alternately or oppositely in the same way as a pinnately compound leaf. This option is also incorrect. 3. **Conclusion**: Based on the analysis of the leaf types, the correct answer is **Pinnately Compound Leaf**. This type of leaf has a midrib that bears multiple leaflets arranged either alternately or oppositely. ### Final Answer: The leaf described in the question is known as a **Pinnately Compound Leaf**. ---

For a circular coil of radius R and N turns carrying current I, the magnitude of the magnetic field at a point on its axis at a distance x from its center is given by B=(mu_0IR^2N)/(2(x^2+R^2)^(3//2)) (a) Show that this reduces to the familiar result for field at the centre of the coil. (b) Consider two parallel coaxial circular coils of equal radius R, and number of turns N, carrying equal currents in the same direction, and separated by a distance R. Show that the field on the axis around the mid-point between the coils is uniform over a distance that is small as compared to R and is given by B=0*72(mu_0NI)/(R) approximately. [Such as arrangement to produce a nearly uniform magnetic field over a small region is known as Helmholtz coils.]

NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which r_"Na"^+ and r_"Cl"^- are 95 and 181 pm respectively , where Cl^- is present at the lattice point of face centered cubic unit cell Na^+ ions are located in void and those compounds which have same crystalline structure also have same coordination system in which Na^+ and Cl^- ions are surrounded by certain number of opposite ions respectively. Under high pressure coordination number changes to 8 :8 type from 6 :6 type. On Subjecting NaCl under high pressure it changes

The meehanism behind nut and bolt arrangement also works for screw gauge. In case of nut and bolt mechanism, with rotation of bolt, it has translational movement also. In one complete rotation of bolt, tip of bolt moves by a linear distance equal to linear distance between two consecutive threads on the screw, known as pitch in case of screw gauge, the circular scale is divided in several parths. The ratio of pitch and total number of divisions on circular scale is known as least count. Spherometer is a device used to measure very small distances such as radius of curvature and thicness of thin plate. The screw gauge can be used to meaure diameter of a spherical sample. A screw gauge has 100 divisions on head scale and in 8 rotations distance covered is 8 mm. A screw gauge has which of the following characteristics ?
