The resistance 2 Ω, 4 Ω and 8 Ω are connected in parallel. Their equivalent

Zigmanuir [339]

Answer:

The answer to your question is the letter B. R = 8/7 Ω

Explanation:

Data

R1 = 2 Ω

R2 = 4Ω

R3 = 8Ω

To calculate the total resistance use the formula

1/R = 1/R1 + 1/R2 + 1/R3

-Substitution

1/R = 1/2 + 1/4 + 1/8

- Look for the Greatest common factor

2 4 8 2

1 2 4 2

1 2 2

The GCF = 2 x 2 x 2 = 8

-Sum up the fractions

1/2 + 1/4 + 1/8 = (4 + 2 + 1) / 8

= 7/8

-Find R

1/R = 7/8 then, R = 8/7 Ω

The drawing shows a hydraulic chamber with a spring (spring constant = 1600 N/m) attached to the input piston and a rock of mass

Triss [41]

Answer:

$\Delta x=245\ mm$

Explanation:

Given:

spring constant of the spring attached to the input piston, $k=1600\ N.m^{-1}$

mass subjected to the output plunger, $m=40\ kg$

<u>Now, the force due to the mass:</u>

$F=m.g$

$F=40\times 9.8$

$F=392\ N$

<u>Compression in Spring:</u>

$\Delta x=\frac{F}{k}$

$\Delta x=\frac{392}{1600}$

$\Delta x=0.245\ m$

$\Delta x=245\ mm$
