when astone is thrown slighty above amoving lorry .where will the stone fall? .2.when loam soil is mixed with sandy soil .what will not change?
To determine where the stone will fall when thrown slightly above a moving lorry, we need to consider the motion of the stone and the lorry.
1. First, let's analyze the motion of the stone. When the stone is thrown, it follows a parabolic trajectory due to the force of gravity acting on it. This means the stone will travel in an arc-shaped path.
2. Now, let's consider the motion of the moving lorry. The lorry is moving in a straight line at a constant velocity.
3. Since the stone and the lorry are moving independently, we can treat them as two separate systems. However, we can assume that both the stone and the lorry are subject to the same gravitational force.
4. When the stone is thrown above the lorry, it will continue to follow its parabolic trajectory until it eventually falls to the ground. The point where the stone will fall depends on the initial velocity and angle at which it was thrown, as well as the time it takes for the stone to travel its arc.
To determine the exact location where the stone will fall, we need more specific information about the initial velocity and angle at which the stone was thrown, as well as the velocity of the lorry. Without these details, we cannot provide a definitive answer.
Moving on to the second question:
When loam soil is mixed with sandy soil, the physical properties of the mixture will change. Loam soil has a balanced combination of clay, silt, and sand particles, whereas sandy soil has a high proportion of sand particles and low organic matter.
1. When loam soil is mixed with sandy soil, the proportions of sand particles in the soil mixture will increase. This means the mixture will become rougher and have a coarser texture.
2. However, there are certain characteristics that will not change when loam soil is mixed with sandy soil. These include the proportions of clay and silt particles, as well as the organic matter content, unless additional amendments or changes are made to the mixture.
So, while the texture and composition of the soil mixture will be altered by adding sandy soil to loam soil, the clay and silt particle proportions and organic matter content will remain unchanged unless further modifications are made.
