Answer:
L
D
Explanation:
At Y, horizontal force is greater than downward force so E or L. However L seems to be more appropriate since horizontal force in L is less than E
At Z, horizontal force is less than downward force so D
Answer:
i) 0.9504
ii) 0.0452
Explanation:
Given data: reliability of hydraulic brakes= 0.96
reliability of mechanical brakes = 0.99
So the probability of stopping the truck = 0.96×0.99= 0.9504
At low speed
case: A works and B does not
= 0.96×(1-0.99) = 0.0096
case2 : B works and A does not
= 0.99×(1-0.96) = 0.0396
Therefore, probality of stopping = 0.0096+0.0396 = 0.0492
The relative humidity is 100%.
To find the answer, we have to know about the relative humidity.
<h3>What is the relative humidity?</h3>
- The amount of water vapor in the air is referred to as humidity.
- The gaseous and invisible condition of water is called water vapor.
- Humidity can be expressed in a variety of ways, including absolute humidity, relative humidity, mixing ratio, and dew point temperature.
- Relative humidity can be expressed as,
- Here, it is given that, the vapor pressure is the same as the saturation vapor pressure, thus,
Thus, we can conclude that, the relative humidity is 100%.

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:
