Answer:
No sand doesn't stay sand forever.
Explanation:
- We may have a thought that the sand we see on the beach areas are always the same one for eternal, but it is not true.
- Due to different activities like beach nourishment, sand replenishment etc. the sand in the beach areas are changed and replaced.
- If the sand remained there for long time, it also affects the sand eating organisms and plants.

Explanation:
Power is the rate at which energy is changing in a circuit. It is shown by the formulas outlined above from the group of answer choices. Since the current (I), voltage (V), and resistance (R) were mentioned in the question, any of three three formulas could be used to obtain the power drawn by the conductor.
If a disk rolls smoothly across a floor, the velocity is zero of the point that is in contact with the floor.
<h3>What is Velocity?</h3>
Observed from a specific point of view and measured according to a specific unit of time, velocity is the direction at which an object is moving and serves as a measure of how quickly its position is changing.
<h3>What is known as velocity?</h3>
A particle or object moves with respect to time when moving at a certain speed, which is expressed vectorially as velocity. Meters per second (m/s) is the commonly used unit for measuring velocity magnitude, also known as speed. A different way to indicate velocity magnitude is with the centimeter per second (cm/s) unit.

Answer:
Explanation:
Given
No of logs
diameter of log
Length of log
42 % of log volume(V) is above water when no one is on raft
so 58 % of log volume(V) is submerged in the water
Weight of 14 log
Buoyancy force on 14 logs
as system is in equilibrium so
Specific gravity of log
The answer is B. Bacteria in the plant nodules convert nitrogen from the soil into molecules the plants can use.
