Answer:

The volume would become 2.34 L if the temperature dropped to 11.0 °C

Explanation:

From the question, A balloon was filled to a volume of 2.50 L when the temperature was 30.0 °C.

To determine what the volume will become if the temperature dropped to 11.0 °C, we will use one of the Gas laws that relates Volume and Temperature. The Gas law that relates Volume and Temperature is the Charlse' law which states that, "the Volume of a fixed mass of gas is directly proportional to its Temperature ( in Kelvin) provided that the Pressure remains constant"

That is

V ∝ T ( at constant pressure)

Where V is the Volume

and T is the Temperature in Kelvin

Then, we can write that

V = kT

Where k is the constant of proportionality

Then,

\frac{V}{T} = k

Hence, we can write that

\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }  = \frac{V_{3} }{T_{3} } ...

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

Where {V_{1} } is the initial volume

{T_{1} } is the initial temperature

{V_{2} } is the final volume

and {T_{2} } is the final temperature

From the question,

{V_{1} } = 2.50 L

{T_{1} } = 30.0 °C = 30.0 + 273.15 K = 303.15 K

{V_{2} } = ??

{T_{2} } = 11.0 °C = 11.0 + 273.15 K = 284.15 K

Putting the values into the equation, we get

\frac{2.50}{303.15} = \frac{V_{2} }{284.15}

∴ V_{2} = \frac{2.50 \times 284.15}{303.15}

V_{2} = 2.34 L

Hence, the volume would become 2.34 L if the temperature dropped to 11.0 °C.

A point charge q1 is held stationary at the origin. A second charge q2 is placed at point a, and the electric potential energy o
Brrunno [24]

The electric potential energy of the pair of charges when the second charge is at point b is 7.3 x 10⁻⁸ J.

<h3>Electric potential energy</h3>

When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.

The electric potential energy between the charges when the second charge is at point b is calculated as follows;

ΔU = -w

Ui - Uf = w

Uf = Ui - w

where;

Uf is the final potential energy

Ui is the initial potential energy

w is the work done by the force

Uf = 5.4 x 10⁻⁸ J - (-1.9 x 10⁻⁸J)

Uf = 5.4 x 10⁻⁸ J + 1.9 x 10⁻⁸ J

Uf = 7.3 x 10⁻⁸ J

Thus, the electric potential energy of the pair of charges when the second charge is at point b is 7.3 x 10⁻⁸ J.

Pleaseeeeeee answer :3!
Ludmilka [50]

Work = (force) x (distance)

Work = (21 Newtons) x (9 meters) = 189 Joules

Power = (work done) / (time to do the work)

Power = (189 Joules) / (3 sec)

Power = (63 watts/sec)

Power = 63 watts (D)

Difference between sold and liquid​
Tcecarenko [31]

Explanation:

Solids have closely packed particles and vibrate about a fixed position, they also have a fixed volume.

liquid have close particles but which are able to move with a bit of kinetic energy, for this reason they have no fixed volume but take the volume of the container or vessel

Concave lenses have
Scilla [17]

Answer:

A. negative; virtual.

Explanation:

A concave lens always forms a virtual erect and diminished image. The reason why is that the image is actually formed by the intersection of virtually extended refracted rays.

Hope this helps!

Find the magnitude of the gravitational force a 63.5 kg person would experience while standing on the surface of Earth with a ma
Anastaziya [24]

Answer: 3976N

Explanation:

Using the formula for calculating gravitational force between two masses, we have

F = GMm/r^2

Where G is the gravitational constant

M and m are the masses

r is the distance between the masses

F= 6.673 × 10-¹¹ × 5.98 × 10²⁴ × 63.5/ (6.37 × 10^6)^2

F= 2.533×10^16/6.37×10^12

F= 0.3976×10⁴N

F= 3976N
