Answer:
The answer is "[tex]-121\ \frac{KJ}{Kg}[/tex]".
Explanation:
Please find the correct question in the attachment file.
using formula:
[tex]\to W=-P_1V_1+P_2V_2 \\\\When \\\\\to W= \frac{P_1V_1-P_2V_2}{n-1}\ \ or \ \ \frac{RT_1 -RT_2}{n-1}\\\\[/tex]
[tex]W =\frac{R(T_1 -T_2)}{n-1}\\\\[/tex]
[tex]=\frac{0.287(25 -237)}{1.5-1}\\\\=\frac{0.287(-212)}{0.5}\\\\=\frac{-60.844}{0.5}\\\\=-121.688 \frac{KJ}{Kg}\\\\=-121 \frac{KJ}{Kg}\\\\[/tex]
How did engineers help to create a ceiling fan
Answer:
The electric ceiling fan was invented in 1882 by engineer and inventor, Philip Diehl.

definition of ceramics
Answer:
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.
Explanation:
Answer:
made essentially from a nonmetallic mineral (such as clay) by firing at a high temperature.

When block C is in position xC = 0.8 m, its speed is 1.5 m/s to the right. Find the velocity of block A at this instant. Note that the rope runs around the pulley B and a pin attached to block C, as indicated.
Answer:
The answer is "2 m/s".
Explanation:
The triangle from of the right angle:
[tex]\to (x_c-0.8)+(1.5+y_4) +\sqrt{x_c^2 + 1.5^2}= constant[/tex]
Differentiating the above equation:
[tex]\to V_c +V_A+ \frac{X_cV_c}{\sqrt{x_c^2 +1}}=0\\\\\to 1-V_A+ \frac{0.8 \times 1.5}{\sqrt{ 0.8^2+1.5}}=0\\\\[/tex]
[tex]\to V_A= \frac{1.2}{\sqrt{ 0.64+1.5}}+1\\\\[/tex]
[tex]= \frac{1.2}{ 1.46}+1\\\\= \frac{1.2+ 1.46}{ 1.46}\\\\ = \frac{2.66}{1.46}\\\\= 1.82 \ \frac{m}{s}\\\\= 2 \ \frac{m}{s}[/tex]

Explanation:
1)A wheel is used to turn a valve stem on a water valve. If the wheel radius is 1 foot and the stem, (axle), radius is .5 inches, what is the mechanical advantage of the wheel and axle? 2)How much resistance force can ideally be overcome when an effort of 80 lbs is applied to the wheel of the water valve in problem 1? 3)What is the linear distance traveled when a 2.5' diameter wheel makes one revolution? 4)A compressor motor has a 1.00 inch output shaft (axle) that drives a 4.00inch pulley (wheel). If the motor output shaft supplies 24 lbs of force, ideally how much force does the pulley apply to the drive belt wrapped around it? 5) If the belt pulley's force is measured to be 4 lbs, what is the AMA wheel and axle here?6) What is the efficiency of the compressor motor – belt pulley wheel and axle?

Read the directions for making a toy parachute.
1. Cut thick string or twine into four pieces that are 9 inches long.
2. Cut a 12x5-inch rectangle out of a plastic garbage bag.
3. Using a hole punch, poke a hole into each corner of the rectangle.
4. Slide the end of each piece of string through a hole in the rectangle.
5. Tie a knot to the end of each string so that they are attached to the corners of the plastic rectangle.
6. Either tape or tie the loose ends of the string to a small object, such as an action figure or toy car.
7. Hold the top of the parachute so that the object hangs loosely below it.
8. Find a high place from which to drop your parachute, such as a chair or a small wall.
9. Softly toss your parachute into the air, and watch it float to the ground.
What would likely happen if someone skipped step 3?
The pieces of string would be different lengths.
The string would not attach to the object.
The string would not attach to the plastic.
The plastic rectangle would be a different size.

A beaker is filled to the 500 ml mark with alcohol. What increase in volume (in ml) the beaker contain when the temperature changes from 5°C to 30°C? (Neglect the expansion of the beaker, evaporation of alcohol and absorption of water vapor by alcohol.) C°, Palcohol = 1.12 x 104/ °C
Answer:
1.4 mL
Explanation:
Given that:
volume of alcohol [tex]V_0[/tex] = 500
Temperature change ΔT = (30° - 5°)C
=25° C
[tex]\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C[/tex]
The increase in volume ΔV = [tex]\alpha \times V_o \times \Delta T[/tex]
[tex]= 500 \times 1.12 \times 10^{-4} / ^0 C\times 25^0 C[/tex]
= 1.4 mL
