Answer: The car has a kinetic energy (because it's in motion) of:
Explanation:
Answer:
Factors determining the state of substances
* Inter molecular force : substances having strong intermolecular force will be solid and substance with weak inter molecular force will be gas.
* Nature of chemical bond:
Ionic compounds are generally solid in nature because of strong intermolecular force.
Polar covalent compounds may be solid or liquid
Non polar covalent compounds generally gas
* Electro negativity difference: greater the electronegativity difference, greater will be the intermolecular force.

Answer:
The hydro static force on the back of the dam is
Explanation:
Given that,
Width b= 1000 m
Depth d= 200 m
We need to calculate the average pressure
Using formula of average pressure
Put the value into the formula
We need to calculate the hydro static force on the back of the dam
Using formula of force
Put the value into the formula
Hence, The hydro static force on the back of the dam is
