The electric field in a region of space has the components ey = ez = 0 and ex = (4.00 n/c · m) x. point a is on the y axis at y = 3.80 m, and point b is on the x axis at x = 4.40 m. what is the potential difference vb − va?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
