Answer:
C. The voltage drop across the resistor is 2.1V and nothing about the current through the resistor.
Explanation:
When connected in parallel, voltage across the resistances are the same. So if 2.1V was dropped across the LED then 2.1V was also dropped across the resistor. However, this tells us nothing about the current through the resistor. We can find the current across the resistor if we know the resistance of the resistor, but that's about it.
If it were a series connection, then the current would have been the same, but the voltage drop were another story.
Answer:
3,13 N
Explanation:
Del enunciado de la segunda ley del movimiento de Newton;
F = ma
Dónde;
F = Fuerza aplicada
m = masa del cuerpo
a = aceleración del cuerpo
Sustitución de valores;
F = 5,9 kg * 0,53 m / seg2 = 3,13 N
Por tanto, la fuerza aplicada es 3,13 N
Answer:
Explanation:
<u>Properties of a virtual image:</u>
1. Image formed cannot be projected or focused on a screen.
2. The distance of the object to the mirror is the same as the distance from the image to the mirror.
3. The size of the image formed is the same as the size of the object.
4. The image formed is laterally inverted. That is the right becomes left and vice versa.
5. The image is upright.
<u>Properties of a real image:</u>
1. Image formed can be projected on a screen.
2, The distance from the image to the mirror is not the same as the distance from the object to the mirror.
3. The size of the image is not the same as the size of the object.
4. Image formed is upside down.
the formula for (momentum) P = (force) F * (Mass) M
P = FM
if mass = 0 momentum = 0
Hope this helps...
