The conversion from gallons to liters is 1 = 3.785.
Keeping this in mind...
42 x 3.785 = 158.97 liters.
If rounding, there are about 159 liters of oil in a barrel.
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer:
The degree of reflection whether faint or bright you see on the surface of an object is an indication that light particles had hit the surface. Since light is a wave and as part of its characteristics can get reflected. However, the amount of light reflected by a surface is dependent on the smoothness of the surface which can be shiny or dull, it can also be dependent on the nature of the surface which can be glass, water, and so on. So, from the question, you can see a faint reflection on the surface of a shiny plate or cup because of the smoothness of the surface which reflects the lights that hit it from a particular direction at the same angle.
Answer:
Energy stored at 12 volt will be 115.2 J and energy stored at 24 volt will be 460.8 volt
Explanation:
We have given capacitance of capacitor C = 1.6 F
Normal voltage V = 12 volt
And system uses 2 volt to charge the system
We know that energy stored in the capacitor is equal to 
So energy stored at 12 volt will be equal to 
And energy stored at 24 volt will be equal to 
So energy stored at 12 volt will be 115.2 j and energy stored at 24 volt will be 460.8 j
