It is called polarizability. A dipole moment is needed for the molecule or atom due to the distortion of the electron cloud. A dipole is a pair of electrical charges that have opposite signs and during a dipole moment two charges separate.
Answer:
D
Explanation:
You should compare your results and data with your original hypothesis. It is okay to have a hypothesis that was shown to be false. That's science. Things do not always work out. You can always discuss what you could have done differently and things that went wrong. There is no right answer in science!
Answer:
Ionosphere
Explanation:
The thermosphere reaches 600 kilometres just above mesosphere and begins immediately above the mesosphere. This layer is where the aurora and satellites appear.
The ionosphere is the comprehensive career of the mesosphere because most of the thermosphere, located 80–400 kilometres just above ground atmosphere.
Auroras — magnificent flowing streaks of light seen in the night sky – appear in this location.
Answer:
When the piano is dropped, the first force acting on it will be the gravitational force, that accelerates the piano at 9.8m/s^2 downwards.
As the piano accelerates, the velocity increases, now appears other force, the air resistance, that opposes to the motion of the piano.
As the velocity of the piano increases, also does the force that the air applies on the piano.
There is a point where the velocity of the piano is such that the air resistance is equal in magnitude, but in the opposite direction, to the force of gravity.
Then the net force on the piano is zero, which means that there is no acceleration, so the piano will keep falling down at constant velocity after this point.
Answer:
Explanation:
usually electricity is sold in the units of kWh, which I will ASSUME is the case here.
85 W (1 kW/1000W)(1hr)(10 p) = 0.85p
60 W (1 kW/1000W)(1hr)(10 p) = <u>0.60p</u>
together they would cost 1.45 p
which would be rounded down to 1 p
