Answer:
The potential energy decreases
Explanation:
- When a proton moves in the direction of the electric field, the force on the proton (f=qE) will be in the direction of the field.
- The proton will accelerate and the KINETIC energy will increase.
- The potential energy decreases.
Answer:
The total energy of the object does not change is the true statement.
Explanation:
1. The force applied to the object is perpendicular to the movement so doesn't work on it, assuming the table is at the same height in all of its points the only energy we have to analyze is the kinetic energy , because the table top is frictionless by Newton's first law the velocity (v) doesn't change so the kinetic energy is constant and the total energy too.
2. There's no friction in this situation
3. As stated on 1. because the applied force is perpendicular to the movement of the object, there force doesn't work on it.
4. There are over one force on the object, the weight and the normal force table top exerts to the object.
So the only true statement is 1.

Answer:
63.4 °C
Explanation:
If we assume the "fixed points" are 0 °C and 100 °C, then the thermometer reading as a function of actual temperature can be described by a linear equation that must have (0, -0.5) and (100, 106) as solutions. We can use these points in the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (106 -(-0.5))/(100 -0)(x -0) -0.5
y = 106.5x -0.5
Then, for x = 60, the thermometer reading is expected to be ...
y = 106.5×60 -0.5 = 63.4 . . . °C
