Answer:
Power rating on the blender = 3809.52 Watts
Explanation:
We have expression for power equal to ratio of work and time,
Energy used by blender = Work done by electricity = 0.8 MJ =
Time of using blender = 3.5 minutes = 210 seconds
So power of blender = 800000/210 = 3809.52 Watts
Power rating on the blender = 3809.52 Watts
Answer:
The correct answer is - Plantae.
Explanation:
Drosera m<em>agnifica</em> is discovered in 2015 for the first time and the characteristics this organism's cell shows are -
- permanent vacuoles
- surrounded by cellulose layer
Vacuoles are present in both Plantae and Animalia kingdom of the eukaryotic organism but in animal cells, there are small and numerous vacuoles present and they are not permanent whereas in plant cells vacuoles are present permanently.
The cell of an animal cell has no surrounding layer other than cell membrane while in the plant cell there is a supporting and protecting layer of cellulose cell wall present.
On the basis of the given characteristics, it is confirmed that the Drosera magnifica belongs to Plantae kingdom.

Concepts and reason
The concept to solve this problem is that if a capacitor is connected in a RC circuit then it allows the flow of charge through circuit only till it gets fully charged. Once the capacitor is charged it will not allow any charge or current to flow.
Opposite is the case with inductor in the RL circuit. According to Faraday's law an inductor develops an emf to oppose the voltage applied but once the flux change stops then the inductor behaves just like a normal wire as if no inductor is there.
In attached figure, resistor is connected in series to the capacitor.
As we considered the voltage across the capacitor and the voltage across the source.
Voltage across a resistor In RC circuit.
Voltage across a resistor In RL circuit.
Answer:
15 miles
Explanation:
Alicia's speed in the first part of the race is:
where is the length of the first part and the time taken to cover this part.
Alicia's speed in the second part of the race is:
where is the length of the second part and the time taken to cover this part.
The total length of the race is
And the total time taken by Alicia to complete the race is
We have in total 4 equations with 4 unknown quantities. From the first 2 equations we find:
And substituting into the second group of equations:
Calling A the first equation and B the second equation, if we compute (A-8B) we get:
And so
So Alicia runs for 1.25 hours at 12 mph (second part of the race). Therefore, the distance travelled during this part is:
Therefore the answer is 15 miles.
