Anywhere from 400 to 600 degrees Celsius
Answer:
They don't have equal velocities
Explanation:
We have one bus travelling from Chicago to New York at 30 m/s and one bus travelling from Chicago to San Francisco at 30 m/s.
This is a cheat question. You need to remember that velocity is a vector. Remember that a vector has a direction and a module. So, the answer will be true, if both buses meet both conditions (direction and module). Let's start to analyze:
Module: In this case is 30 m/s for both buses
Direction: In this case is where the buses are heading. One is going to New York, and one is going to San Francisco. So the directions are different.
As module and direction are not the same for both buses we can say that they don't have equal velocities.
Answer:
2dQ²/2εA = 2U₀
Explanation:
The energy stored in the ideal parallel plate capacitor U = Q²/2C. For a parallel plate capacitor, C = εA/d where A is the area between the plates and D is the distance between them. So
U = Q²/2C = Q²/2εA/d = dQ²/2εA. At distance d₁ = d, U = U₀,
U₀ = dQ²/2εA,
When d₂ = 2d, U₁ = d₂Q²/2εA = 2dQ²/2εA = 2U₀
The lack of a subscript after the 0 means that there is only one oxygen (0).
There are 2 hydrogen molecules and 1 oxygen molecules
