A long wire carrying 4.50 A of current makes two 90° bends, as shown in the figure (Figure 1). The bent part of the wire passes through a uniform 0.244 T magnetic field directed as shown in the figure and confined to a limited region of space. EMINA Find the magnitude of the force that the magnetic field exerts on the wire. ΫΠΙ ΑΣΦ | F= N

The consumption rate of electricity, in kW/h has increased, on average, at 4.5% per year. If it continues to increase at this rate indefinitely, find the number of years before the electric companies will need to double their generating capacity The electric company will need to double their generating capacity about every years. (Do not round until the final answer. Then round to the nearest tenth as needed)

Vaughn Co. uses a standard job cost system with a normal capacity of 26,200 direct labour hours. Vaughn Co. produces 12.900 units, which cost $169,400 for direct labour (24,200 hours), $25,800 for variable overhead, and $135,450 for fixed overhead. The standard. variable overhead per unit is $2 (2 hours at $1 per hour), and the standard fored overhead per unit is $10.00 (2 hours at $5.00 per hour). Calculate the fixed overhead production volume variance. Fixed overhead production volume variance $ 24000 Unfavourable
