All the angles of reflection are +3° off, so systematic error.
The device used to measure the angle might be miscalibrated or have incorrect markings.
Answer:
2. +0.2 C
Explanation:
When the two spheres touch, the total charge will be redistributed such that the two spheres are at same potential:

The potential can be rewritten as ratio between the charge on the sphere (Q) and the capacitance of the sphere (C):

Since the two spheres are identical, they have same capacitance:

So we can write


And since the total charge is

And this charge will be redistributed equally on the two spheres (
), we have

Answer:
10.84 m/s2 radially inward
Explanation:
As the car is traveling an a constant tangential speed of 80.8 m/s, the total acceleration only consists of the centripetal acceleration and no linear acceleration. The formula for centripetal acceleration with respect to tangential speed v = 80.8 m/s and radius r =602 m is

b) The direction of this centripetal acceleration is radially inward
