A 60-watt light bulb has a voltage of 120 bolts applied across it and a current of 0.5 amperes flows through the bulb. What is t
Andre45 [30]

Answer:

240 ohms

Explanation:

From Ohms law we deduce that V=IR and making R the subject of the formula then R=V/I where R is resistance, I is current and V is coltage across. Substituting 120 V for V and 0.5 A for A then

R=120/0.5=240 Ohms

Alternatively, resistance is equal to voltage squared divided by watts hence \frac {120^{2}}{60}=240

A map of eastern North America, showing the pH of rainfall in the various states, indicates that the pH of rain in New York Stat
pogonyaev

4.22

Explanation:

The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.

The pH scale expresses the acidity or alkalinity of aqueous solutions.

  • The pH scale ranges from 1 to 4
  • An acidic solution will have a pH value less than 7

We have given a range of values between 4.22 to 4.40

  This implies that the pH values of rainfall in this region falls between these extremes.

   The least value 4.22 is the most acidic

    The value 4.4 is the the least acidic

The lower the pH value, the more acidic a solution is.

A fugitive tries to hop on a freight train traveling at a constant speed of 5.5 m/s. Just as an empty box car passes him, the fu
stiks02 [169]
Th equations to be used here are the following:

a = (v - v₀)/t
x = v₀t + 0.5at²

The speed of the fugitive is the sum of his own speed plus the speed of the train. Thus, 
v₀ = 0 + 5.5 m/s = 5.5 m/s
v = 8 m/s + 5.5 m/s = 13.5 m/s

a.) We use the first equation to determine time
2.5 m/s² = (13.5 m/s - 5.5 m/s)t
Solving for t,
t = 3.2 seconds

b.) We use the answer in a) and the 2nd equation:

x = (5.5 m/s)(3.2 s) + 0.5(2.5 m/s²)(3.2 s)²
x = 30.4 meters
