hidden lines

These are dotted lines
These are used to describe hidden spaces .
Like if a cube is drawn then we can't see the diagonal inside from corner to corners so we represent it as dashed lines

A piston-cylinder assembly contains 0.5 lb of water. The water expands from an initial state where p1 = 40 lbf/in.2 and T1 = 300

VARVARA [1.3K]

Answer:

W = 31.393 Btu

Explanation:

given data

piston-cylinder assembly contains water = 0.5 lb

p1 = 40 lbf/in² = 40 × 144 lbf/ft²

T1 = 300° F

p2 = 14.7 lbf/in² = 14.7 × 144 lbf/ft²

pv 1.2 = constant.

solution

we use here superheated table A 4E to get value for p1 = 40 and t = 300

v1 = 11.04 ft³/lbm

so we know

$P_2 \times V_2^{1.2} = P_1 \times V_1^{1.2}$ ,...............1

$14.7 \times V_2^{1.2} = 40 \times (11.04)^{1.2}$

solve it we get

v2 = 25.425 ft³/lbm

and here

W = $(\frac{P_1V_1 - P_2V_2}{n-1}) m$ ...............2

put here value we get

W = $(\frac{40\times 144\times (11.04) -14.7 \times 144\times (25.425) }{1.2-1})0.5$

solve it we get

W = 31.393 Btu

A laminated steel ring is wound with 3000 turns. When the magnetism current varies between 7 and 9 A, the magnetic flux varies b

Klio2033 [76]

Answer:

60000 H

Explanation:

We are given;

Number of turns; N = 3000 turns

Change in flux = 900 - 860 = 40 Wb

Change in current = 9 - 7 = 2 A

Now, the formula for incremental inductance is given as:

L = N(Change in flux/Change in current) where;

N is Number of turns

Plugging in the relevant values, we have;

L = 3000(40/2)

L = 60000 H.

Name the force acting on the handles of a plastic shopping bag that is full of groceries.

Dimas [21]

The answer is

The force acting on the handles of a plastic shopping bag that is full of groceries are gravitational force, muscular force.

Gravitational force works downwards, and muscular force is applied by the hands lifting bucket upwards. Two forces are in the opposite direction and hence balancing each other. As a result net force is zero.
