- Equilibrium
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):

Essential Mineral Elements
Mineral Elements:
A large number of inorganic elements are necessary for all the life processes and hence should be taken into our diets in adequate amounts. Any deficiency in these minerals leads to an abnormality in the metabolic functioning of the body.
Essential Mineral Elements in Plants
There are two types of minerals that are essential for plant growth, such as:
1. Macrominerals
Minerals like Phosphorous, carbon, silicon, magnesium, hydrogen, sodium, nitrogen, potassium, calcium, oxygen, selenium, and sulfur are required in abundance for proper plant growth and are also found abundantly in plant tissues. Hence, they are known as macrominerals.
2. Microminerals
A few minerals like Iron, boron, zinc, cobalt, chlorine, nickel, manganese, copper, molybdenum, etc. are required in lesser quantities for proper growth by the plants and therefore, they are called microminerals. Further they are also called trace elements.
