What is the Gravitational Potential Energy of a 30kg block resting 5m above the ground? O 150 J
O 1500 )
O 6J
O 60)

1470J

Explanation:

Given parameters:

Mass of the block  = 30kg

Height  = 5m

Unknown:

Gravitational potential energy  = ?

Solution:

The Gravitational potential energy of body is due to its position above the ground level.

 Gravitational potential energy  = mass x acceleration due to gravity x height

So;

Gravitational potential energy  = 30 x 9.8 x 5 = 1470J

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
