  • This group includes diatoms and golden algae (desmids), found in fresh water as well as in marine environments.
  • In diatoms the cell walls form two thin overlapping shells embedded with silica.
  • diatoms have left behind large amount of cell wall deposits in their habitat, which accumulated over billions of years is referred to as ‘diatomaceous earth’ .
  • Most of them are photosynthetic and are the chief ‘producers’ in the oceans.

The relation tan  = v is wrong because the dimensions on both the sides of the equation are not equal.

Dimension of right hand side is [MoL1T-1

Dimension of Left hand side quantity is [MoLoTo

Hence, the equation is wrong. 

To make the relation dimensionally correct, R.H.S should be divided by the speed of the rainfall. 

That is, 

, is a dimensionally correct relation.

Typing ke time square kaise likha aapne

Gaurav Seth 3 hours ago

Given Equation is 2sin²x + 3cosx = 0

 

⇒ 2(1 - cos²x) + 3cosx = 0

 

⇒ 2 - 2cos²x + 3cosx = 0

 

⇒ 2cos²x - 3cosx - 2 = 0

 

⇒ 2cos²x - 4cosx + cosx - 2 = 0

 

⇒ 2cosx(cosx - 2) + (cosx - 2) = 0

 

⇒ (2cosx + 1)(cosx - 2) = 0

 

⇒ cosx - 1/2, cosx = 2[Not possible]

 

⇒ cosx = -1/2

 

⇒ x = 120°,240°

 

⇒ x = (2π/3) + 2πn, x = (4π/3) + 2πn

S.No.                       SPEED                     VELOCITY
1. It is defined as the rate of change of distance. It is defined as the rate of change of displacement.
2. It is a scalar quantity. It is a vector quantity.
3. It can never be negative or zero. It can be negative,zero or posituve.
4. Speed is velocity without direction. Velocity is directed speed.
5. Speed may or may not be equal to velocity. A body may possess different velocities but the same speed.
6. Speed never decreases with time. For a moving body, it is never zero. Velocity can decrease with time. For a moving body , it can be zero.
7. Speed in SI is measured in ms-1 Velocity in SI, is measured in ms-1
