Answer:
figure c
Explanation:
a neutral body has the same number of charge that's the negatives and positive charges are equal.
Answer: 20 meters
Explanation:
This situation is related to vertical motion, especifically an object in free fall, and the parametric equation that describes this motion is:
![y=y_{o}+V_{o}t-\frac{g}{2}t^{2}](https://tex.z-dn.net/?f=y%3Dy_%7Bo%7D%2BV_%7Bo%7Dt-%5Cfrac%7Bg%7D%7B2%7Dt%5E%7B2%7D)
Where:
is the stone's final height
is the stone's initial height
is the initial speed of the stone
is the time the stone is falling
is the acceleration due gravity
Isolating
according to the given information:
![y_{o}=\frac{g}{2}t^{2}](https://tex.z-dn.net/?f=y_%7Bo%7D%3D%5Cfrac%7Bg%7D%7B2%7Dt%5E%7B2%7D)
![y_{o}=\frac{10 m/s^{2}}{2}(2 s)^{2}](https://tex.z-dn.net/?f=y_%7Bo%7D%3D%5Cfrac%7B10%20m%2Fs%5E%7B2%7D%7D%7B2%7D%282%20s%29%5E%7B2%7D)
Finally:
This is the distance the stone fell
Dark energy is what is causing the accelerating expansion of the universe. It can also be defined as the theoretical energy that counteracts or acts against gravity. Others also define it as a theoretical, new kind of dynamic energy field that fills space, but whose energy has an effect opposite to that of normal energy.
Answer:
A
Explanation:
Iron and gadlinium are both very easily made into magnetic substances. Cobalt is also capable of being magnetized. Aluminum, put in an alloy, can make a magnetic substance, but
Aluminum by itself is not able to be magnetized.
