Answer:

B = 0.287  Tesla

According to thumb rule the direction of magnet is to the east.

Explanation:

F = BiL sin∅

note that F = mg

B = magnetic field

i = current

therefore,

mg = BiLsin∅

Make B subject of the formula

B = mg/iLsin∅

m/L = mass per length of the wire and it is given in gram per centimeter . It should be converted to kg per meter.

m/L = 0.440 g/cm

convert to kg/m = 0.440 × 0.001 kg × 100 m = 0.044  kg/m

B = 9.8 × 0.044 / sin 90 × 1.50 × 1

B = 0.4312/ 1.50

B = 0.28746666666

B = 0.287  Tesla

According to thumb rule the direction of magnet is to the east.

Explanation:

General partners are individuals, two or more , who come together to own a business and controls daily activities of the business. Each member has unlimited liability and their action can legally bind the activities of the business. They share profit and losses equally.

According to fact pattern 27-3, if the partners agree to dissolve one of their business line- equity lending as in the case above and the company's assets are shared among the partners, it would result in the termination of the firm's legal existence.

Once there is a breach by any of the partners as contained in the partnership agreement and the partner's asset shared, that is dissolution. The partnership business has therefore been terminated legally and cease to exit.

xenn [34]

Answer:

$245.09

Explanation:

A service contract for a video projection system costs $90 a year. You expect to use the system for three years.

Instead of buying the service contract, the future value of these annual amounts after three years if you earn 5 percent on your savings will be:

PV  

Ordinary Annuity

​  =C×[  ((1−(1+i)  ^−n ) / i ]

where

n = number of years = 3

i = interest rate = 5%

Present Value of the annuity = 90 x [ ((1 - (1+0.05)^-3) / 0.05] = $245.09
