In the National Grid, the Step Up Transformer increases the amount of voltage that is passing through the grid at any one time. These are used at power stations, as without them, there would not be enough power to transport the electricity around the national grid.
Hope this helps :)
B or d most likely, because a frequency table you can show for example the amount of time the plant grew to 30 cm in 87 degree feirenhieght
Answer:
20.7 billion = 20.7E9 converting to units of 10
20.7E9 km = 20.7E12 m
t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s
69000 s = 1150 min = 19.2 hrs
Answer:
D) Points down
Explanation:
We can find the direction of the magnetic field produced by each of the wire by using the right hand rule:
- the thumb must correspond to the direction of the current in the wire
- the other fingers wrap around the thumb and gives the direction of the magnetic field lines
For the wire on the right, we have:
- thumb (current): towards you
- other fingers (magnetic field): at the left of the wire, they point down
For the wire on the left, we have:
- thumb (current): away from you
- other fingers (magnetic field): at the right of the wire, they point down
So, both magnetic fields point down at the point halfway between the two wires, so the net field is also pointing down.
Explanation:
Electronegativity is the ability of an atom to attract electrons, when it forms a chemical bond in a molecule. However, it is not strictly an atomic property, since it refers to an atom within a molecule. The equivalent property of electronegativity for an isolated atom is electronic affinity.
