Answer: find the answer in the explanation
Explanation:
Average velocity is the average value of magnitude of initial velocity and final velocity.
If U = initial velocity and V = final velocity, then average velocity can be expressed as
Average velocity = ( U + V )/2
A vehicle who takes 60 minutes to cover 30 miles north and then 30 miles south and end up at the same place, has an average speed of 60 miles divided by 60 minutes, or 1 mile per minute.
Instantaneous velocity is the distance covered in a specific direction per time taken. Instantaneous velocity can be expressed as
Velocity = displacement/ time.
Uniform velocity occurs when we have a constant velocity. That is, when velocity does not change. When a vehicle travels in equal distances in equal intervals of time.
By definition, Variable is "(of a quantity) able to assume different numerical values." By this, an example is 4x, as x is an unknown number, but has a value.
Constants are one constant value, unlike Variables.
Hahahahaha. Okay.
So basically , force is equal to mass into acceleration.
F=ma
so when F=ma , we get acceleration=6m/s/s
Force is doubled.
Mass is 1/3 times original.
2F=1/3ma
Now , we rearrange , and we get 6F=ma
So , now for 6 times the original force , we get 6 times the initial acceleration.
So new acceleration = 6*6= 36m/s/s
Number of atoms equal the number of molecular orbitals as each atom has 1 atomic orbital and 1 electron.
Therefore,
Number of atoms = (mass/molar mass)*Avogadro's number = (7.90/22.99)*1.36*10^23 = 4.67*10^22 atoms.
Then,
Number of molecular orbitals = 4.67*10^22
