An object accelerates uniformly (constantly) from 3.8 m/s east to 9.8 m/s east in 2.0 s. What is the magnitude (numerical amount) of the object’s acceleration?

An electric current is flowing through the cord below. what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

Explain why electric current cannot exist if a current doesn't have a voltage source.

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)
