Answer:
The correct answer is option A.
Explanation:
Force is defined as push or pull on an object with mass due to which change velocity occurs (acceleration).
![a=\frac{dv}{dt}[tex][tex]m\times \frac{dv}{dt}[tex]We are given with large truck and small car at constant speed, which means that acceleration zero.[tex]a=\frac{dv}{dt}=0](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bdv%7D%7Bdt%7D%5Btex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5Dm%5Ctimes%20%5Cfrac%7Bdv%7D%7Bdt%7D%5Btex%5D%3C%2Fp%3E%3Cp%3EWe%20are%20given%20with%20large%20truck%20and%20small%20car%20at%20constant%20speed%2C%20which%20means%20that%20acceleration%20zero.%3C%2Fp%3E%3Cp%3E%5Btex%5Da%3D%5Cfrac%7Bdv%7D%7Bdt%7D%3D0)
if ,v = constant
Net force on the vehilce
F = Normal - Weight
0 = N = W
N = W
So, the force experienced by the object will be due to its mass, and higher the mass more will be the experienced by an object.So, large truck will experience larger net force.

The answer is A). Moving from A to C the temperature and the kinetic energy increases.
Answer:
t = 96.1 nm
Explanation:
For strong reflection through liquid layer we know that the path difference between two reflected light rays must be integral multiple of wavelength
now we know that the path difference of two reflected light from thin liquid layer is given as
here we know that
t = thickness of layer
N = 0 (for minimum thickness of layer)
now we have
