According to Ohm's law for a portion of the circuit we have:
U=RI=>I=U/R=24/3=8 A
The correct answer is B
A group of scientists claim that a new type of fuel will help reduce greenhouse gas emissions. to evaluate this claim you can a. calculate the price of producing the fuel. b. study the effect of a fuel spill on wetland ecosystems. c. determine the efficiency of the fuel in different types of engines. d. test the amount
Answer:
The velocity of the center of mass of the two-object system remains constant during the experiment.
The relationship if time according to the speed of light can be represented using Lorentz' time-dilation equation:
T = To / sqrt( 1 - (v^2/c^2) )
Where:
T = new time = ?
To = original time = 1 minute
v = velocity = 0.6c
c = speed of light
Substituting the given values:
T = 1 / sqrt( 1 - (0.6c^2/c^2) <span>)</span>
T = 1 / sqrt( 1 - (0.6^2) <span>)
</span>T = 1.25
Therefore, the alarm clock would ring for 1.25 minutes.
