False because only a variables can be factors
For this problem, we use the equations derived for rectilinear motion at constant acceleration. The equations are:
a = (v - v₀)/t
x = v₀t + 0.5at²
where
a is acceleration
v and v₀ are the final and initial velocities, respectively
x is the distance
t is the time
First, let's determine the a to be used in the second equation:
a = (7.5 m/s - 0 m/s)/1.7 s = 4.411 m/s²
x = (0)(1.7s) + 0.5(4.411 m/s²)(1.7 s)²
x = 6.375 m
B; to produce a hypothesis.
I think is True! Is the best answer. Because the trumpet it make them sounds like the lips with the musician and it vibrate.
Answer:
Correct answer: There are four variables rather than two - The amount of charge q₁, the amount of charge q₂, the distance between the spheres and the relative dielectric permeability εr of the medium.
Explanation:
I assume you meant two spherical objects.
The force between two charged objects according to Coulomb's law is calculated by the formula:
Fc = 1/ (4 π ε₀ εr) · (q₁ · q₂) / d²
where :
- ε₀ is the dielectric permeability of the vacuum
- εr is the dielectric permeability of the medium
- q₁ the amount of charge of the first sphere
- q₂ the amount of charge of the second sphere
- d is the distance between the spheres
