Answer:

The volume of the gas decreases 140 times.

Explanation:

The equation of state of the ideal gas is described below:

P\cdot V = n\cdot R_{u}\cdot T (1)

Where:

P - Pressure.

V - Volume.

n - Molar quantity.

R_{u} - Ideal gas constant.

T - Temperature.

From this formula we construct the following relationship:

\frac{P_{1}\cdot V_{1}}{T_{1}} = \frac{P_{2}\cdot V_{2}}{T_{2}} (2)

Where:

P_{1}, P_{2} - Initial and final pressure.

V_{1}, V_{2} - Initial and final volume.

T_{1}, T_{2} - Initial and final temperature.

\frac{V_{2}}{V_{1}} = \frac{\frac{T_{2}}{T_{1}} }{\frac{P_{2}}{P_{1}} }

If we know that \frac{T_{2}}{T_{1}} = \frac{1}{14} and \frac{P_{2}}{P_{1}} = 10, then the change in the volume of the gas is:

\frac{V_{2}}{V_{1}} = \frac{\frac{1}{14} }{10}

\frac{V_{2}}{V_{1}} = \frac{1}{140}

The volume of the gas decreases 140 times.

Infrared telescopes are usually placed on high-flying airplanes or on satellites in space __________
Yuliya22 [10]

Answer:

In order to improve visibility

Explanation:

Infrared telescopes are made using infrared cameras that contain infrared detectors which are solid-state and are maintained at very cold (cryogenic) temperatures

Infrared radiation is absorbed by water vapor which is present in the Earth's atmosphere, leading to the limitation of the use of infra red telescopes at high altitudes such as mountains, high flying planes or satellites

A girl pulls her younger brother on a sled along a flat sidewalk (the total mass of the sled is 30kg). A frictional force of 50N
harkovskaia [24]

Answer:

6.13 s

219 N

Explanation:

Newton's law in the x direction:

∑F = ma

150 cos 30° N − 50 N = (30 kg) a

a = 2.66 m/s²

Δx = v₀ t + ½ at²

(50 m) = (0 m/s) t + ½ (2.66 m/s²) t²

t = 6.13 s

Newton's law in the y direction:

∑F = ma

Fn + 150 sin 30° N − (30 kg) (9.8 m/s²) = 0

Fn = 219 N

What is the mass of a truck in grams of it produces a force of 1500N while accelerating at a rate of 6 m/s²?​
aleksley [76]

Answer:

250,000

Explanation:

<h2> </h2>

<h2>formula = ( F=ma </h2>

  • F=1500N
  • a=6m/s^2
  • F= ma
  • m=?
  • 1500/6 = m
  • m=250 kg
  • 1kg =1000gm so 250kg =250,000gm
  • m =250×10^3 gm
