Answer:
1.08×10⁹ J
Explanation:
From the question given above, the following data were obtained:
Power (P) = 100 kilowatt
Time (t) = 3 hours
Energy (E) =?
Next, we shall convert 100 kilowatt to Watts. This can be obtained as follow:
1 KW = 1000 W
Therefore,
100 KW = 100 KW × 1000 W / 1 KW
100 KW = 100000 W
Thus, 100 KW is equivalent to 100000 W.
Next, we shall convert 3 hrs to second (s). This can be obtained as follow:
1 h = 3600 s
Therefore,
3 h = 3 h × 3600 s / 1 h
3 h = 10800 s
Thus, 3 h is equivalent to 10800 s.
Finally, we shall determine the amount of energy consumed as follow:
Power (P) = 100000 W
Time (t) = 10800 s
Energy (E) =?
P = E/t
100000 = E / 10800
Cross multiply
E = 100000 × 10800
E = 1.08×10⁹ J
Therefore, 1.08×10⁹ J of energy was consumed.
Explanation:
The second law states that the greater the mass of an object, the more force it will take to accelerate the object. There is even an equation that says Force = mass x acceleration or F=ma. This also means that the harder you kick a ball the farther it will go.
Answer:
The minimum thickness of the oil is 77.55 nm
Explanation:
Given:
Refractive index of oil 
Refractive index of water 
Wavelength of light
m
From the equation of thin film interference,
The minimum thickness is given by,

Where
,
thickness
Here we have to find minimum thickness so we use



m
nm
Therefore, the minimum thickness of the oil is 77.55 nm
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
