Answer:
heterogeneous and homogeneous
Explanation:
Hetero you can separate whilst homo is combined and cant be separated
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.
Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
solution:
We know v0 = 0, a = 9.8, t = 4.0. We need to solve for v
so,
we use the equation:
v = v0 + at
v = 0 + 9.8*4.0
v = 39.2 m/s
Now we just need to solve for d, so we use the equation:
d = v0t + 1/2*a*t^2
d = 0*4.0 + 1/2*9.8*4.0^2
d = 78.4 m
