Jeff takes his expensive blazer to Laundry Ltd. to be dry-cleaned. Jeff has had his suits dry-cleaned by Laundry Ltd. on numerous previous occasions. On the wall of the laundry is a notice which purports to exempt Laundry Ltd. from liability "for any damage done to items left to be cleaned".

Jeff has never given this notice any thought even though he has read it.

On this occasion, however, Jeff enquires of the attendant as to its meaning. She tells him that it is simply a warning to customers to check the washing instructions for their items of clothing.

Jeff hands over his blazer and then signs a receipt for the blazer. On the back of the receipt is a single paragraph labelled "CONDITIONS" which states:

"Laundry Ltd. does not accept any liability for any damage caused to any item. It is the responsibility of the customer to ensure that any special laundering instructions are drawn to the attention of Laundry Ltd. before the item is handed over to Laundry Ltd."

Advise Jeff who now informs you that when he went to pick up his blazer yesterday he noticed that a button was missing and that the lining of the blazer was torn.

all i have to say is that people are truly ignorant and don't have anything better to do with their lives.

answer:

It is because each question is allowed up to only 2 answers. So they split is in half so an equal number of points goes to each of the response writers.

Explanation:

So say if you post a question for 10 points, then each response earns 5 points a piece.

Explanation:

Interaction of a Current Loop with a Magnetic Field The effects due to the interaction of a current-carrying loop with a magnetic field have many applications, some as common as the electric motor. This problem illustrates the basic principles of this interaction. Consider a current I that flows in a plane rectangular current loop with height a = 4.00 cm and horizontal sides b = 2.00 cm . (Figure 1) The loop is placed into a uniform magnetic field B→ in such a way that the sides of length a are perpendicular to B→, and there is an angle θ between the sides of length b and B→, as shown in the figures. (Figure 2) Part A Will the interaction of the current through the loop with the magnetic field cause the loop to rotate? Yes, the net torque acting on the loop is negative and tends to rotate the loop in the direction of decreasing angle θ (clockwise). Yes, the net torque acting on the loop is positive and tends to rotate the loop in the direction of increasing angle θ (counterclockwise). No, the net torque acting on the loop is zero and the loop is in equilibrium. No, the net force acting on the loop is zero and the loop is in equilibrium. Part B Assume that the current flowing into the loop is 0.500 A . If the magnitude of the magnetic field is 0.300 T , what is τ, the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field? Express your answer in newton-meters. τ = N⋅m
