The current in the junction is 1350 mA or 1.350 A.
Explanation:
As per Kirchoff's first law, the algebraic sum of current meeting at any junction should be equal to the algebraic sum of current leaving the junction. As in the present case, three parallel branch circuit is given the current in 250 mA, 300 mA and 800 mA, respectively, the sum of these three current will be equal to the current in the junction.
So,
I₁+I₂+I₃ = I₄
So I₁,I₂ and I₃ are the current passed in the three parallel branches and I₄ is the current in the junction.
250 + 300 + 800 = 1350 mA
So the current in the junction is 1350 mA or 1.350 A.
Climate change is the reason for a lot of factors such as:
Heat-trapping Greenhouse Gases And The Earth's Climate
Greenhouse Gases
Reflectivity or Absorption of the Sun's Energy
Changes in the Earth's Orbit and Rotation
Variations in Solar Activity
Changes in the Earth's Reflectivity
Volcanic Activity
There's a lot more that I could list, but hopefully this will do.
Yes yes ! How right you are ! Truer words were never spoken.
Its total mechanical energy is <em>2,000 J</em>.
We don't have enough information to say anything about its heat energy, its chemical energy, or the energy due to any electrical charge it may be carrying or any magnetic field it may have.
Answer: 1000 Hz · 0,5 m = 500 m/s
Explanation: speed = frequency · wavelength
