The indian ocean is the third largest ocean at 68,556,000 sq km
Answer:
The impedance of this circuit is 200 ohm.
Explanation:
Given that,
rms voltage = 120 v
Frequency = 60.0 Hz
rms current = 0.600 A
We need to calculate the impedance
Using formula of impedance

Where,
= rms voltage
= rms current
Z= impedance
Put the value into the formula


Hence, The impedance of this circuit is 200 ohm.
Answer:
Answer:
It has sunlight, oxygen, water, and fertile soil.
Explanation:
Sunlight: provides plants (producers) with energy so that the ecosystem is sustainable. Also provides heat and warmth so the planet does not freeze.
Oxygen: obvious. required for human survival and survival of most carbon-based organisms.
Water: required for plant growth and sustainability of carbon-based life.
Fertile soil: a place where plants can grow and produce energy.

Answer:
Explanation:
Plotting the original location of the helicopter before it flies 25 km north, it would be at the origin, (0,0) then after it flies north, the y vertex gains 25 points, so it would be (0,25)
After it flies east, the x coordinate gains 5 points, so it would now be (5,25)
After it flies south, the y coordinate loses or is subtracted by 5 points. so it would now be (5,20)
After flying west, the x coordinate loses 15 points. So the final vertex would be at (-10,20)
East = Right
West = Left
South= Down
North = Up
I used mainly mathematical methods by adding and subtracting the x and y coordinate values, but this could be graphed easily since I gave the coordinates just incase!
Hope this helps!
Answer:
Explanation:
Given
Lowest four resonance frequencies are given with magnitude
50,100,150 and 200 Hz
The frequency of vibrating string is given by

where n=1,2,3 or ...n
L=Length of string
T=Tension
Mass per unit length
When string is clamped at mid-point
Effecting length becomes 
Thus new Frequency becomes

i.e. New frequency is double of old
so new lowest four resonant frequencies are 100,200,300 and 400 Hz
