A 27 W light bulb is connected to a 7.8 V battery. How much current flows through
the bulb?

3.46 A

Explanation:

electrical power = current × voltage

P = I × V

We have,

V = 7.8

P = 27

Thus, I  = P ÷ V

I = 27 / 7.8

= 3.46 A

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
