A helium balloon containing 5m³ of gas at a pressure of 30kPa is released into the air. Assuming that the temperature is constant calculate the volume the balloon would have when the pressure inside the balloon has fallen to 5kPa. Answer in m³.

Answers

Answer:

30 m³

Explanation:

Parameters given:

Initial volume of helium, V1 = 5 m³

Initial pressure in balloon, P1 = 30 kPa

Final pressure, P2 = 5 kPa

To find the volume of the balloon at that volume, we apply Boyle's law.

It states that at constant temperature, the pressure of a gas is inversely proportional to the volume of the gas.

Mathematically:

P = k / V

Where k = constant of proportionality

This implies that:

P * V = k

This means that if the pressure or volume of the gas changes at the same temperature, the product of the pressure and volume would be the same:

Hence:

P1 * V1 = P2 * V2

Hence, to find the final volume:

30 * 5 = 5 * V2

=> V2 = (30 * 5) / 5

V2 = 30 m³

The volume of the gas when the pressure is 5 kPa is 30 m³.

Opposite electric charges will repel, and like charges will attract.

Answers

As it stands now, that statement is false.

There are two ways to make the statement true:

#1). Exchange the places of the words "Opposite" and "like".

#2). Exchange the places of the words "repel" and "attract".

Either ONE of these changes will make the statement true.
Doing BOTH of these changes will leave it false.

Answer:

False. Opposite electric charges will attract, and like charges will repel.

Recall that the height of an object t seconds after it begins moving when gravity is the only force acting on the object is given. h(t)=-16x^2 + v0t + h0. h(t) is given in feet. v0 = initial velocity of object in ft/sec. ho= initial height of object in feet. If the feather is dropped from the top of the bridge 90 feet above a river, how long does it take the feather to reach the water?

Answers

That's pretty easy, have a look :

$h(t)=−16x2=v0t+h0$
$v0=0 ft/sec$
$h0=90 ft$

The only thing you need to do is to find t and the problem is solved.

Answer:

Time taken, t = 2.37 seconds

Explanation:

It is given that,

Height of an object at time t is given by :

$h(t)=-16t^2+v_0t+h_0$

Where

v₀ is initial velocity of object

h₀ is initial height of the object

The feather is dropped from the top of the bridge 90 feet above a river. we have to find the time taken by the feather to reach the water.

At the surface of water, h(t) = 0 and v₀t = 0

So, $0=-16t^2+0+90$

t = 2.37 seconds

The feather will take 2.37 seconds to reach the water surface.

An electron in a hydrogen atom undergoes a transition from the n = 3 level to the n = 6 level. To accomplish this, energy, in the form of light, must be absorbed by the hydrogen atom. Calculate the energy of the light (in kJ/photon) associated with this transition.

Answers

Answer: $1.816* 10^(-19) J$

Explanation:

Given

$E=(hc)/(\lambda )$

$E=2.18* 10^(-18)((1)/(n_1^2)-(1)/(n_2^2))$

where h=Planck constant

c=speed of light

$E=2.18* 10^(-18)((1)/(3^2)-(1)/(6^2))$

$E=2.18* 10^(-18)* (1)/(12)$

$E=1.816* 10^(-19) J$
