Answer:
v = 4.10 10⁻³ m / s
Explanation:
For this exercise we will use Newton's second law where the force is magnetic
F -W = m a
As the field is directed to the north and the proton to the east, using the rule of the right hand the force is vertical upwards, the force balances the weight the acceleration is zero
F = W
q v B = m g
Let's calculate the speed
v = m g / (q B)
v = 1,673 10⁻²⁷ 9.8 / (1.6 10⁻¹⁹ 2.5 10⁻⁵)
v = 4.10 10⁻³ m / s
All you have to do is add 600 + 1,400 which = 2,000
So your answer is D) 2,000 J
I hope this helps. :)
I had the same test btw
It has to gain three more electrons to satisfy the octet rule.
Because <span>two organisms with exactly the same </span>niche can't survive in the samehabitat<span> (because they compete for exactly the same resources, so one </span>will<span> drive the other to extinction). However, species whose </span>niches<span> only partly overlap may be able to coexist.</span>
Answer:
<em>Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. ... When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet.</em>
