The statement: “According to Faraday's law, voltage can be changed by moving magnets away from the coil of wire.”, is true. Any type of movements done (away, into or out, toward, rotation, etc.) on the magnetic environment would always generate a voltage. In Faraday’s law, it is clear that there are different ways on how to generate a voltage.
<span>The atoms are grouped thus forming molecules. Each type of molecule is the combination of a certain number of atoms linked between them and in a specific way, whenever a molecule can contain atoms of different elements or of the same. And that in turn, Each atom retains its structural characteristics, beyond that they are part of different molecules because during the chemical reactions the atoms cannot be created or destroyed, but they are organized in a different way creating links between an atom and another.</span>
671mi/hr
= 671/60min (calculates miles/min)
= (671/60) ÷ 60seconds (calculates miles/sec)
((671/60) ÷ 60)× 1609m
= 299.899 meters/sec
= 299.90m (round off to 2 decimals )
Average acceleration = (change in speed) / (time for the change)
The missile's change in speed is (5,000 - 0) = 5,000 m/s
Average acceleration = (5,000 m/s) / (10 sec)
= 500 m/s² (about 51 Gs)
Inconveniently, this isn't one of the choices on the list. Is there something wrong, either with the choices or with my solution ?
No. Relax. Everything is OK.
500 meters is the same thing as 0.5 kilometer. So my answer can also be written as 0.5 km/s² . That doesn't change anything, and it IS one of the listed choices.
The average acceleration is <em>0.5 km/sec² (d)</em> .
The answer would be Gravity.
Gravity is pulling the weight down, which is pulling the car up the ramp.
