The volume of a gas at 59.0kPa is 600ml. if the pressure is increase to 138.0kPa, what will be the new volume?

Physics

likoan [24]3 years ago

Answer:

<h3>The answer is 256.52 mL</h3>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{59000 \times 600}{138000}  =  \frac{35400000}{138000}  \\  = 256.521739...

We have the final answer as

<h3>256.52 mL</h3>

Hope this helps you

A toy spacecraft is launched directly upward. When the toy reaches its highest point, a spring is released and the toy splits in
Murljashka [212]

Answer:

A

Explanation:

Momentum conservation will cause 0.08kg to move to the west (opposite of 0.02 kg).

and because both are at the same height above the ground, they will take the same time to reach the ground.

The speed of 0.08kg will be less than 0.02 kg, let v be the speed of 0..02kg, then speed of 0.08kg V is

0.02v - (0.08)V = 0

V = 0.02 v/ 0.08 = v/4

The speed of 0.08 kg = v/4

The speed of 0.08 kg is less than 0.02kg.

So 0.02kg strikes the ground farther from the launch point than does the 0.08 kg

You are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-foc
vfiekz [6]

Explanation:

Given that, you are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-focal-length lens in your camera for a 960 mm telephoto lens such that,

m_1=960\ mm

m_2=60\ mm

We need to find the the factor with which the size of the image increases. It can be calculated by taking ratios of both m_1\ and\ m_2

So, \dfrac{m_1}{m_2}=\dfrac{960}{60}

\dfrac{m_1}{m_2}=16

So, the size of image increases by a factor of 16. Hence, this is the required solution.

The equation T^2=A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A
kobusy [5.1K]

Answer:

D. 2^(3/2)

Explanation:

Given that

T² = A³

Let the mean distance between the sun and planet Y be x

Therefore,

T(Y)² = x³

T(Y) = x^(3/2)

Let the mean distance between the sun and planet X be x/2

Therefore,

T(Y)² = (x/2)³

T(Y) = (x/2)^(3/2)

The factor of increase from planet X to planet Y is:

T(Y) / T(X) = x^(3/2) / (x/2)^(3/2)

T(Y) / T(X) = (2)^(3/2)

Doubling the distance between you and a source of radiation decreases your exposure by:
Elan Coil [88]

Given what we know, we can confirm that doubling the distance between you and a source of radiation decreases your exposure by 75%.

<h3>How is distance related to radiation exposure?</h3>
  • As expected, increasing the distance from the source of the radiation will reduce its negative effects.
  • Counter-intuitively however, doubling the distance does not reduce by half, but rather reduces its effects by 3/4th.
  • This is due to the fact that the radiation effects from the source are inversely proportional to the square of the distance.
  • This causes the changes to be far greater than expected.

Therefore, given that the radiation is proportional to the square of the distance, instead of being of a more direct relation, we can confirm that when doubling the distance between yourself and the source of the radiation, you can reduce its effects by 3/4 or 75%.

Coiling wire around an iron core and applying an electric current through the wire creates a temporary magnet called an electrom
Serggg [28]

Answer:

C) Use a battery with more voltage.

Explanation:

The equation for the magnetic field around a coil is given by,

B = μ₀NI

where,

B = Magnetic flux density

μ₀ = permeability

N = number of turns per meter

I = Current in the wire

So when using a higher voltage battery, more current passes through the battery as resistance of the wire remains the same.
