The automobile beltway around many cities is approximately circular. Suppose that you start driving at point A on the east side
of the beltway and drive counterclockwise at an unchanging 90 km/hr (Figure 3.13). As you pass point B on the north side, what is your speed? Your velocity?

Answer:
0.546
Explanation:
From the given information:
The force on a given current-carrying conductor is:
where the length usually in negative (x) direction can be computed as
Now, taking the integral of the force between x = 1.0 m and x = 3.0 m to get the value of the force, we have:
where;
current I = 7.0 A
F = 546 × 10⁻³ T/mT
F = 0.546
Using KE=1/2mv^2
v=
so v=10
v=
so v=10
Answer:
The volume of the cylinder is
Explanation:
Given that,
The height of the cylinder is 13 cm
Radius of the cylinder is 4 cm
We need to find the volume of the cylinder. The formula that is used to find the volume of a cylinder is given by :
So, the volume of the cylinder is
