When a flat mirror forms an image, how does the angle of light rays that reaches your eyes compare to the angle of the rays striking the mirror

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

True or false graphs must include scales that increase by the same amount

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
