Thomson's model included Protons and Electrons. His model is referred to as 'Plum Pudding' because of it.
Answer:
Counting the number of colonies that arise on a pour plate can calculate the concentration by multiplying the count by the volume spread on the pour plate. Direct counting methods are easy to perform and do not require highly specialized equipment, but are often slower than other methods

Answer:
Explanation:
There are three types of interactions involved between the particles when solution are formed.
1 : Solute - solute interaction:
2 : Solute - solvent interaction:
3 : Solvent - solvent interaction:
1 : Solute - solute interaction:
It is the inter-molecular attraction between the solute particles.
2 : Solute - solvent interaction:
It involve the inter-molecular attraction between solvent and solute particles.
3 : Solvent - solvent interaction:
It involve the intermolecular attraction between solvent particles.
Solutions are formed if the intermolecular attraction between solute particles are similar to the attraction between solvent particles.
Exothermic process:
The process will exothermic when solute solvent bonds are formed with the release of energy and energy required to brake the solute-solute particles and solvent solvent particles are less.
Endothermic process:
The process will be endothermic when energy required to break the solute-solute particles and solvent solvent particles are higher than energy released when solute solvent bonds are formed .
Answer : The correct option is B- Towards the left.
Solution : Given,
Force on car in upward direction, = 6000 N
Force on car in downward direction, = 6000 N
Force on car in right direction, = 5000 N
Force on car in left direction, = 6000 N
Force : Force is equal to the mass multiplied by the acceleration. The force is directly proportional to the acceleration.
Formula : F = m × a
where, F is force, m is mass and a is acceleration.
From the given diagram we conclude that the and are in opposite direction and the force acting on car are same. So, their net force is zero.
And in case of and , the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because is higher than the .
So, the car will accelerate towards left direction.
I think the answer to that is B
