B. Matter moves at right angles to the direction of a longitudinal wave, and at right angles to the direction of a transverse wave.
C. A longitudinal wave does not need matter through which to travel, while a transverse wave does.
D. A longitudinal wave needs matter through which to travel, while a transverse wave does not.
Answer:
B
Explanation:
Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.

If Linh removes bulb 3,the bulbs which will remain lit are 1, 2 and 4.
The electric circuit provided with battery creating potential difference across resistance or capacitor or inductors.
When Linh removes the middle branch, the bulbs 1, 2 and 4 will be acting as resistor which are in series connection. The current flow will be same in all the resistors except 3.
Thus, If Linh removes bulb 3, the bulbs which will remain lit are 1, 2 and 4.

Answer:
Atom X will accept electrons from atom Y
Explanation:
The outermost shell of an atom is full when it contains 8 valence electrons (except for the first shell, which only contains 2 electrons). Therefore, any atom tends to accept electrons if it's very close to complete the shell with 8 electrons, or to donate electrons if it has only a few electrons in its outest shell.
In this case, we have:
- Atom X: 6 valence electrons --> it tends to accept electrons, since it needs only 2 of them to complete the shell
- Atom Y: 2 valence electrons --> it tends to donate electrons, so it has its outermost shell completed also
- Atom Z: 8 valence electrons --> it has no tendency in donate/accept electrons, since its outermost shell is already full
Therefore, atom Y will donate its 2 valence electrons to atom X, so that both of them have their outermost shell completed.
Answer:
Atom X will accept electrons from atom Y

-palm
-fingers
-back
-thumb
Answer: Palm
Explanation: When you have a wire, you must point your thumb in the direction in which the electricity is going, and now you close your palm, in the direction in which you closed your hand is in the direction in which points the magnetic field.
Then the correct option is the first one, the palm points in the direction of the magnetic field.
Answer:
Fingers
Explanation:
The index finger shows the moving charge, while your middle finger shows the magnetic field line.
