Answer:
a) The US power rating for the european bulb must be 27.27 W
b) The current in the United Stated for the european bulb is 0.227A
Explanation:
First of all the bulb is not going to light in 120V like it does in 220V, the bright is going to be much lower (near 1/4). Now, lets take a look on a circuit perspective:
The bulb in a circuit is modeled like a simple resistor, so we have a resistor conected to a voltage source, see figure 1. There we have a current given by:
Where is the 220v Input voltage, R is the resistance from the bulb. In the problem we have the power consumption in watts given by:
Clearing
Now, from ohm's law
So 484 ohm is the resistance from the bulb.
Now in the circuit lets replace the voltage source from 220v to 120v and lets calculate the current, and the power consuptiom
And the power consuptiom:

Answer:
a) Deceleration = 201.76 m/s^2
b) Distance traveled = 197.68 m
Explanation:
Initial Speed = 632 mi/h
Initial Speed (in meters/second) = (632 * 1.609 * 1000) / (60 * 60) = 282.4 m/s
Time to decelerate = 1.4 seconds
a) Change in speed = Acceleration * time
-282.4 = Acceleration * 1.4
Acceleration = -201.76 m/s^2
Deceleration = 201.76 m/s^2
b) Distance traveled = average speed * time
average speed = 282.4 / 2 = 141.2 m/s
Distance traveled = 141.2 * 1.4
Distance traveled = 197.68 m
Answer:
Because it is the result of two more fundamental units, a derived unit is termed that. For volume, the cubic meter (m³) is the fundamental unit of area. Any number that cannot be measured directly with any equipment is referred to as a derived unit. For example, we can't quantify a substance's density using a rule, scale, or bucket.
