Answer:
it means match the correct words
Answer:
Part a)
at t = 3.00 s
at t = 20.0 s
Part b)
at t = 3.00 s
at t = 20.0 s
Explanation:
The car starts at x = 0
Part a)
Now at t = 3.00 s
the position of the car is given as x = 25 m and its speed is given as v = 11 m/s
Now for average velocity we have
Now for average acceleration we have
Part b)
Now at t = 20.0 s
the position of the car is given as x = 385 m and its speed is given as v = 45 m/s
Now for average velocity we have
Now for average acceleration we have
When you brew a coffee you're creating a Solution.
Tiny particles from coffee grounds, or solutes, are dissolved in water, the solvent.
Given,
Potential energy, U(x)=3x-x^{3}
Force is given by, F=dU/dx
F= d(3x-3x^{3})/dx
=3-3x^{2}
For F=0 N,
3-3x^{2} =0
3x^{2} =3
x=√1
Therefore, at x=+1 and x= -1, the force for the given potential energy is zero.
