The electric force due to a uniform external electric field causes a torque of magnitude 16.0 ×× 10−9−9 N⋅mN⋅m on an electric dipole oriented at 30∘∘ from the direction of the external field. The dipole moment of the dipole is 8.5 ×× 10−12−12 C⋅mC⋅m. What is the magnitude of the external electric field? If the two particles that make up the dipole are 2.5 mm apart, what is the magnitude of the charge on each particle?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
