Answer:
43.83
N
Explanation:
Given that,
The mass of an object, m = 34.4 kg
The coefficients of static and kinetic frictions for plastic on wood are 0.53 and 0.40, respectively.
The force of static friction,

The force of kinetic friction,

Net force acting on the object is :
F = 178.67-134.84
= 43.83 N
Hence, this is the required solution.
Electrons have a smaller wavelength than visible light, leading to higher resolution.
Answer:
Explanation:
Given
mass of ice cube 
inclination 
Spring constant 
initial compression 
Suppose Initially the cube is at the datum and it moves h height after release
So Elastic Potential Energy of Spring will convert to Potential Energy of cube



so final Potential Energy will be
Initial Potential Energy
B.Initially spring is at compression so energy associated with it is its Elastic Potential Energy i.e. 0.125 J
Final Energy
Inorganic chemical compounds
Explanation:
Inorganic chemical compounds employ the use of oxidation numbers of atoms to write their chemical formula.
- The oxidation number is the formal charge assigned assigned to an atom present in a molecule or formula unit or ion based on some rules.
- Knowledge of this number is used in writing the formulae of inorganic compounds.
- These compounds forms by the exchange of certain small whole numbers by atoms or groups of atoms.
- The combining power usually correspond to the number of electrons usually lost or gained or shared by atoms of elements during chemical combinations or the number of positive or negative charges carried by ions.
For example:
A B
combining power(Valency): X Y
Exchange of valencies Y X
Molecular formula of compound A
Bₓ
