- A 300 kg box of supplies is dropped from a plane and has a parachute attached, if it accelerates down at 2m/s? what resistive force does the parachute supply?

2340 N

Explanation:

There are two forces on the box.  Weight force pulling down and resistive force pushing up.

Sum of forces in the y direction:

∑F = ma

F − mg = ma

F = mg + ma

F = m (g + a)

F = (300 kg) (9.8 m/s² + (-2 m/s²))

F = 2340 N

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
