The acceleration is the same for both the bullet fired and dropped
Answer:
Hey there!
This viewpoint probably comes from somebody who believes in the functionalism approach.
Let me know if this helps :)
Answer:
A
Explanation:
There is a mechanical advantage in this system....
she only needed 100 N to lift 500 N
1:5 she lifted it 2 meters, so if there WAS NO friction, she would have to pull in 5 x 2 = 10 meters
but there IS friction so she must have pulled in MORE than 10 m
Below are the answers:
a. There is a constant magnetic Feld, which means B is constant, so we can rewrite the change in fux as above.Because ΔA is positive, there will be a negative emf in the loop, corresponding to an induced magnetic momentpointing to the left on the page. The current in the loop will be into the page at the top and out of the page at<span>the bottom
</span>V=-Δφ/ Δt = -B·ΔA/ Δ<span>t
b. </span>As the loop’s radius is increasing, we can think about individual electrons in the wire loop as moving radially<span>outward. We’ll consider one in the top of the loop (which is moving up the page). Using the Lorentz ²orce Law
</span>F=q(~v⇥~B)=qvB(ˆy⇥ˆx)=-qvB<span>ˆ
</span>Constant forces pointing into the center of the loop will result in circular orbits (around the wire). Because the<span>force is pointing into the center of the loop, we know we have positive current at that point (into the page).</span>
Answer:
number of quantum states = 8
Explanation:
To find the total number of allowed states you take into account the following relations:
in this case you have:
furthermore, for each n,l,ml quantum state you have two additional states due to the spin of the electrons.
then, you have (n,l,ml) = (2,0,0), (2,1,-1), (2,1,0), (2,1,1) and with the spin:
number of quantum states = 2*(1+3) = 8
