A) TOTAL Resistance = 41+18+120 = 179 ohms
<span>Current = V/R = 9 / 179 = 0.0503 A = 50.3 mA </span>
<span>B) V = I*R = .0503 * 41 = 2.06 V </span>
<span>C) V = I*R = .0503 * 18 = 0.91 V </span>
<span>D) V = I*R = .0503 * 120 = 6.03 V</span>
Answer:
(a) 
(b) 
Explanation:
(a) Since a constant external force is applied to the body, it is under an uniformly accelerated motion. Using the following kinematic equation, we calculate the final velocity of the mass if it is initially at rest(
):
According to Newton's second law:
Replacing (2) in (1):
(b) In this case we have 
. So, we use the final velocity equation:
Answer:
I believe <u>chemicals</u>, though I might be wrong.

Answer:
Llegara a su destino a la 1:00 pm
Explanation:
Si el coche va a 90 km/h buscamos un numero q al multiplicarlo por 90 nos de 450. Entonces 90×5 = 450, si hacemos la cuenta desde las ocho de la mañana mas las 5 horas del viaje terminaria llegando a su destino a la 1:00 pm.
From the Hooke's law , the extension force of an elastic material is directly proportional to the extension.
That is, F = k e, where F is the force , k is the constant and e is the extension
F = 10 × 10 = 100 N
e = 1mm or 0.001 m
Hence, k = F/e
= 100 N/ 0.001
= 100000 N/m or 100 N/mm
