Question O Purchasing Additional Insurance. Nancy is a widow with two teenage children Nancy's gross income is $2,800 per month and taxes take about 24% of her income Using the income method, Nancy calculates she will need to purchase about eight times her disposable income in life insurance to meet her needs. Therefore, she will need to purchase life insurance in the amount of S204.288. Now assume that Nancy's employer provides her with two times her annual gross salary in life insurance. How much additional insurance should Nancy purchase? The amount of additional Insurance Nancy should purchase is $ (Round to the nearest dollar)

A 29-g bullet is shot vertically into an 8-kg block. The block lifts upward 4.0 mm (see the figure). The bullet penetrates the block and comes to rest in it in a time interval of 0.0010 s. Assume the force on the bullet is constant during penetration and that air resistance is negligible. The initial kinetic energy of the bullet is closest to A) 43 J B) 58

A 22-3 bullet is shot vertically into an 4-kg block. The block lifts upward 6.0 mm (see the figure). The bullet penetrates the block and comes to rest in it in a time interval of 0.0010 s. Assume the force on the bullet is constant during penetration and that air resistance is negligible. The initial kinetic energy of the bullet is closest to O 21 J O 29 J O 0.24 J O 43 J 1.3x10-3 Submit Request Answer

Shown in the figure below is a long solenoid. Your solenoid has N loops, a length of L, and is carrying a current of I. We shall use the "long" approximation for which the field outside the solenoid is very very small compared to the field inside the solenoid. Use an Ampere path that extends the full length of the solenoid and closes outside the solenoid. N turns in the coil www00000000000) L A "Long" Solenoid (i.e. length >> diameter) What is the length of your Ampere path over which the field is not negligible? What is the current though this path? Use Ampere's Law to determine the FORMULA for the magnetic field inside the solenoid: What is the direction of the magnetic field inside the solenold? Toward the right Toward the left Clockwise as viewed from the left Counter-clockwise as viewed from the left Out of the screen Into the screen Toward the top of the screen Toward the bottom of the screen The solenoid in the picture looks like a "stretched out" spring because the loops of the coil are far apart. If you compressed the coil so that the loops are touching (same number of loops, same current), what would happen to the magnetic field? The field would increase The field would briefly increase then settle to the original value. The field would decrease Not enough information given. The field would stay the same. An EMP would be generated disabling nearby computer equipment. The field would briefly decrease then settle to the original value. length of L, and is carrying 3 current of J.

Part A A 51.0 kg ice skater is gliding along the ice, heading due north at 4.40 m/s. The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, but flik = 0 Suddenly, a wind from the northeast exerts a force of 4.20 N on the skater. Use work and energy to find the skater's speed after gliding 100 m in this wind. Express your answer with the appropriate units.
