KiRa [710]3 years ago

Answer:

In the air

Explanation:

There are three states of matter:

- Solids: in solids, the particles are tightly bond together by strong intermolecular forces, so they cannot move freely - they can only vibrate around their fixed position

- Liquids: in liquids, particles are more free to move, however there are still some intermolecular forces keeping them close to each other

- Gases: in gases, particles are completely free to move, as the intermolecular forces between them are negligible

For this reason, it is generally easier to compress/expand the volume of a gas with respect to the volume of a liquid.

In this problem, we are comparing water (which is a liquid) with air (which is a gas). From what we said above, this means that the change in volume is larger in the air rather than in the water.

El sargento Conejero toma el sol en su colchoneta, de 2 m2 de superficie, flotando en el agua de la piscina (d = 1 g/cm3 ). Si o
galben [10]

Answer:

  W = 529.2 N

Explanation:

We can solve this problem using the translational equilibrium equation, where the forces are the weight of the sergeant and the thrust of the water given by Archimedes' principle

         B - W = 0

where the thrust is

          B = ρ g V_liquid

The volume of the displaced liquid is

          V = A h

   

we substitute

         ρ g A h = W

We reduce the magnitudes to the SI system

         h = 2.7 cm = 0.027 m

         ρ = 1 g / cm3 = 1000 kg / m³

let's calculate

          W = 1000 9.8 2 0.027

          W = 529.2 N

The electric field between two parallel plates is uniform, with magnitude 646 N/C. A proton is held stationary at the positive p
Ahat [919]

Answer:

The distance from the positive plate at which the two pass each other is 0.0023 cm.

Explanation:

We need to find the acceleration of each particle first. Let's use the electric force equation.

F=Eq

ma=Eq

<u>For the proton</u>

m_{p}a_{p}=Eq_{p}

a_{p}=\frac{Eq_{p}}{m_{p}}

a_{p}=\frac{646*1.6*10^{-19}}{1.67*10^{−27}}

a_{p}=6.19*10^{10}\: m/s^{2}

<u>For the electron</u>

m_{e}a_{e}=Eq_{e}

a_{e}=\frac{Eq_{e}}{m_{e}}

a_{e}=\frac{646*1.6*10^{-19}}{9.1*10^{−31}}  

a_{e}=1.14*10^{14}\: m/s^{2}

Now we know that the plate separation is 4.26 cm or 0.0426 m. The travel distance of the proton plus the travel distance of the electron is 0.0426 m.

x_{p}+x_{e}=0.0426

Both of them have an initial speed equal to zero. So we have:

\frac{1}{2}a_{p}t^{2}+\frac{1}{2}a_{e}t^{2}=0.0426

t^{2}(a_{p}+a_{e})=2*0.0426

t^{2}=\frac{2*0.0426}{a_{p}+a_{e}}

t=\sqrt{\frac{2*0.0426}{6.19*10^{10}+1.14*10^{14}}}

t=2.73*10^{-8}\: s    

With this time we can find the distance from the positive plate (x(p)).

x_{p}=\frac{1}{2}a_{p}t^{2}

x_{p}=\frac{1}{2}6.19*10^{10}*(2.73*10^{-8})^{2}

x_{p}=0.0023\: cm

Therefore, the distance from the positive plate at which the two pass each other is 0.0023 cm.

I hope it helps you!

In principle, the motion of a simple pendulum and an object on an ideal spring can both be used to provide the basic time interv
stich3 [128]

Answer:

Explanation:

The time period of the pendulum containing simple pendulum is given by

T = 2\pi \sqrt{\frac{L}{g}}

where, L is the length of the pendulum and g is the value of acceleration due to gravity.

The time period of the clock using the spring mechanism is given by

T = 2\pi \sqrt{\frac{m}{k}}

where, m is the mass of the block attached to the spring and k is the spring constant.

here we observe the time period of the pendulum depends on the value of acceleration due to gravity. The value of acceleration due to gravity decreases as we go on the heights that means when the clock is taken to the mountain, the value of g decreases and thus, the value of time period increases and the clock runs slow.

So, the clock containing the spring system gives the accurate reading rather than the clock containing simple pendulum.
