I NEED HELP!!!
True [87]

Answer:

Explanation:

Formula

Heat = m * c * delta t

t = temperature in centigrade.

The first thing you have to do is convert kelvin degrees to centigrade. The conversion factor is - 273. The formula is degrees centigrade = degrees kelvin - 273. It is easier to understand with a couple of examples.

  • 290o K = 290 - 273 = 17
  • 325. K =   325 - 273 = 52

Solution

Heat = 100.0 grams * 4.18 J/g*C * (52 - 17)

Heat = 100 * 4.18 * 35

Heat = 14630 Joules

But you want kj

Heat = 14630 / 100 = 14.63

Answer

Heat = 14.6 kj

Solve for Voltage
vladimir1956 [14]

Answer:

110V

Explanation:

Given parameters:

Current in the lightbulb  = 0.5A

Resistance  = 220Ω

Unknown:

Voltage  = ?

Solution:

To solve this problem, we apply the equation derived from ohm's law;

          V  = IR

So,

       V = 0.5 x 220  = 110V
