Answer:
3.03e-19 J
Explanation:
Use the formula E = hc/λ
Where:
h (Planck's constant) = 6.626e-34 J*s
c (speed of light, constant) = 3.00e8 m/s
λ (wavelength) = 656e-9 m
E = energy (in Joules)
E = (6.626e-34 * 3.00e8) / 656e-9 = 3.03018293e-19 = 3.03e-19 J
For every action there is an equal and opposite reaction. Newton's Third Law of Motion.
Physical is when something is changed by not changeing its compond like if u melt an ice cube its still that same material and was not changed by something else and and chemical change is when something is changed my acids or changes completly like rusting iron or acid rain and burning stuff
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.
