What is the power, in Watts, of a bulb that transfers 30 joules per second?

30 Watts

Explanation:

In Science, power can be defined as the rate at which work is done.

Mathematically, power is given by the formula;

Where,

Given that power = 30 J/secs

Since we know, work is the rate of transfer of energy. Thus, power is the rate of expending energy.

1 J/secs = 1 W

Therefore, 30J/secs = 30W.

Where, J/secs = Joules per seconds.

W = Watts.

a.   mass number from atomic number

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
