The correct Answer is:
To solve the question regarding the movement of minerals in the soil during heavy rain, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks about the process by which minerals in the upper layers of soil move downward during heavy rain. 2. **Identify the Options**: The options provided typically include terms related to soil and water movement, such as leaching, weathering, erosion, and smearing. 3. **Define Leaching**: Leaching is the process where soluble substances (like minerals) are washed out from the soil due to the action of percolating water, particularly rainwater. This process allows minerals to move from the upper layers of the soil to deeper layers. 4. **Differentiate from Other Processes**: - **Weathering**: This refers to the breaking down of rocks and minerals at the Earth's surface but does not specifically involve the downward movement of minerals due to water. - **Erosion**: This involves the removal of soil and rock from one location to another, often by wind or water, but does not specifically refer to the downward movement of minerals in soil. - **Smearing**: This term is not commonly used in the context of soil mineral movement and is incorrect in this context. 5. **Conclude the Correct Answer**: Based on the definition and the differentiation from other processes, the correct answer to the question is **leaching**. ### Final Answer: The process by which minerals in the upper layers of the soil move downward during heavy rain is known as **leaching**. ---

It is well known that a rain drop falls under the influence of the downward gravitational force and the opposing resistive force. The latter is known to be proportional to the speed of the drop, but is otherwise undetermined. Consider a drop of mass 1.0g falling from a height of 1.00km. It hits the ground with a speed of 50.0ms^(-1) (a) What is the work done by the gravitational force ? (b) What is the work done by the unknown resistive force ?

A transverse sine wave of amplitude 10 cm and wavelength 200 cm travels from left to right along a long horizontal stretched, string with a speed of 100 cm/s. Take the origin at left end of the string. At time t = 0 the left end of the string is at the origin and is moving downward. Then the equation of the wave will be ( in CGS system )

As shown in the right figure, a point light source is placed at distance 2f from a lens with focus length f. and a screen is placed at 4f from the lens. The lens is then cut at the middle into two equal portions: upper half and lower half. the upper half is moved upwards by a small distance d comparable to the light wavelength and the lower half is moved downwards by the same distance d. What is the light pattern on the screen?

A block of mass m is connected to a spring (spring constant k ). Initially the block is at rest and the spring is in its natural length. Now the system is released in gravitational field and a variable force F is applied on the upper end of the spring such that the downward acceleration of the block is given as a=g-alphat , where t is time elapses and alpha=1m//s^(2) , the velocity of the point of application of the force is:

A spring having a spring constant k is fixed to a vertical wall as shown in Fig. A block of mass m moves with velocity v torards the spring from a parallel wall opposite to this wall. The mass hits the free end of the spring compressing it and is decelerated by the spring force and comes to rest and then turns the spring is decelerated by the spring force and comes to rest and then turns back till the spring acquires its natural length and contact with the spring is broken. In this process, it regains its angular speed in the opposite direction and makes a perfect elastice collision on the opposite left wall and starts moving with same speed as before towards right. The above processes are repeated and there is periodic oscillation. Q. What is the time period of oscillation ?
