Answer:
T surface = 3.9°C
Explanation:
given data
emissivity 0.6
absorptivity = 0.2
solar radiation is incident rate = 1200 W/m²
solution
we get here surface temperature by equality of emitted and absorbed heat rate that is
Q (absorbed) = Q (heat ) .................1
α Qinc =
T surface = ..........................2
put here value and we get
T surface =
T surface = 276.9 K
T surface = 3.9°C
Answer:
D) 242 meters per second
Explanation:
The tsunami speed (or phase velocity) is independent of the wave period; it dispersion relation is given in terms of the acceleration of gravity g by the following equation:
Where D = water depth, and g = gravity (9.81 m /seg2)
Considering 6000meters as our water depth:
meters per seconds
I hope you find this information useful and interesting! Good luck!
Answer:
d) phase sequence of the voltage applied to the motor stator windings
Explanation:
The direction of rotation of a three-phase squirrel-cage induction motor depends on the phase sequence of the voltage applied to the motor stator windings.
The true statement about the dot plot is 1 has 4 and 0 dots.
Explanation:
- after creating a Bar chart 4 is the right answer.
- The highest among st all the other plots is 1 but 4 shows 3.
- Taking an average from all the data points 3 comes to the right answer.
- Median the central Mid-point is 3.
- Mode also comes to 3.
- It is skewed on the right due to the 1st one.
- Skewed shows the data point either increasing or in decreasing.
- There a to Bi- histograms which has two ups and downs.
- The true statement has to be as Mean=Median=Mode is 3.
I think it might be false correct me if I’m wrong
