Heya! I would greatly appreciate if anyone could help me with these two questions. I don't exactly understand them that well. Thank you! 1. "Tony Schumacher is a NHRA Top Fuel drag racer. He holds the world record for the fastest quarter mile pass where he reached a speed of 150.2 m/s is 3.667 seconds. What was his acceleration?"
2. "An F16 fighter jet at a high altitude is flying at 472 m/s and acceleration to 611 m/s in 7.2 seconds. What is the acceleration of the fighter jet?"

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0

If a negatively charged particle is placed at rest in an electric potential field that increases in the positive x-direction, what will the particle do? a. accelerate in the positive x-direction b. remain at rest c. accelerate in the negative x-direction
