Xander drew a diagram of a candle and its reflection in a mirror as shown below. how should xander describe the reflection? the reflection of the candle in the concave mirror formed an upside-down real image that is smaller than the candle. the reflection of the candle in the convex mirror formed an upside-down real image that is smaller than the candle. the reflection of the candle in the concave mirror formed an upside-down virtual image that is smaller than the candle. the reflection of the candle in the convex mirror formed an upside-down virtual image that is smaller than the candle.

The force will determine the acceleration.

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
