A 20.0 N force is applied at an angle of 40.0 degrees above the horizontal to a 4.00 kg box. The box moves a horizontal distance of 4.00 meters. Friction is negligible. The work done by the 20.0 N force is a. 61.3 J.

b. 46.3 J.

c. 50.1 J.

d. 75.0 J.

The work done by the 20 N force is 61.3 J

Explanation:

20 N Force at horizon is: F=20 N*cos 40=15.32 N

The work done by 20 N at horizon is: W=F*S=15.32 N* 4 m=61.3 J

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
