A change that will not affect the pressure in a container:

The factors that affect the pressure inside a container are PVT (Pressure, Volume and Temperature). Apart from these three factors, changing or tweaking any other factor like, changing the material using which the container was made, etc would not affect the pressure.

In this case of a container, a change in pressure(adding or removing air from the container), volume (changing the amount of fluid present in the container), temperature (changing the temperature in which the container is kept) would all affect the pressure inside the container while something like, changing the material using which the container was made, would not change the pressure.

pogonyaev

Answer:

4.13×10⁻⁷ m

Explanation:

Applying

v = λf................... Equation 1

Wherfe v = speed of light, λ = wavelength of light, f = frequency of light.

make λ the subject of the equation

λ = v/f....................... Equation 2

Note: Light is an electromagnetic wave, and all electromagnetic wave moves with thesame speed which is 3×10⁸ m/s.

From the question,

Given: f = 7.26×10¹⁴ Hz

Constant: v = 3×10⁸ m/s

Substitute these values into equation 2

λ = (3×10⁸)/(7.26×10¹⁴)

λ = 4.13×10⁻⁷ m

A 2.50 kg ball is attached to a 3.00 m bar and swung in a vertical circle. If the ball does not leave the circular loop, what mi

dezoksy [38]

Answer:

5.42 m/s

Explanation:

At minimum speed, the tension in the bar will be 0 when the ball is at the top of the arc, so the only force is gravity pulling down.

Sum of forces towards the center of the circle:

∑F = ma

mg = m v²/r

v = √(gr)

v = √(9.8 m/s² × 3.00 m)

v = 5.42 m/s

what is the final volume of a gas with an initial volume of 200 .0ml if the pressure decreases from 500.0 kpa to 250.0 kpa

Serjik [45]

Answer:

Given Data:

V2 ?

V1 = 200 ml,

P1 = 500kpa and P2 = 2500kpa

From Boyels law (Ideal gas law) Where temperature remains constant, Pressure is inversely proportional to volume.

P1 .V1 = P2 . V2 ; T=Constant

V2 = (P1.V1) ÷ P2

= (500×200) ÷(250)

= 400 ml

The final volume of the gas is 400 ml.

Note: Increased pressure decreases the volume or decreased pressure increase the volume as they are inversely proportional. Here in our answer pressure decreases from 500 kpa to 250 kpa so volume increases from 200 ml to 400 ml.
