Answer:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

ANSWER
Both trucks will move together with speed v = 6.67 m/s
so correct answer will be
The speed of the combined vehicles is less than the initial speed of the truck.
EXPLANATION
As we know that there is no external force on the system of two trucks
So here momentum of the two trucks before collision and after collision will remain same
So here we will have
so here we will have
now we will have
so correct answer will be
The speed of the combined vehicles is less than the initial speed of the truck.
Answer:
First law of thermodynamic state that energy is always conserved, in other word, energy cannot be created or destroyed.
This means that energy can only transfer from one source to another.
For example, the electricity we used to power our phone didn't come from nowhere.
We charge our phone using the energy from the electricity from the outlet.
The outlet gets its energy from the power plant, who generated that energy from burning coal.
The coal they burned got their energy while they were alive as plants.
The plants got their energy from the sun.
The sun got its energy from other cosmic stuff and so on...
My point is that the energy we use will always cycle around. It doesn't come from thin air and it doesn't disappear into thin air either. This help keeps things balance because if energy is created out of thin air then the earth might just blow up. If energy gets erased into thin air then there'll be nothing to fuel life.
Answer:
1917723.40119 m/s
Explanation:
m = Mass of deuteron = 
k = Boltzmann constant = 
T = Temperature = 
RMS velocity is given by
The RMS velocity of the deutrons is 1917723.40119 m/s
It would be aligning with the north pole.
