Answer:

The full cycle of Moon phases takes on average 29 nine days and 12 hours for 8 phases when i name the “minimal moon” as a distinct phase (it vary a bit over and under that because Earths orbit is elliptical).

That gives us 2 half cycles of 4 phases each:

Minimal Moon. The moon show hardly any crescent and the bit of crescent it do show is nearly horizontal. Earth, Moon and Sun is near conjunction (on the same line, there may be a solar eclipse in mid phase).

New Moon (aka Waxing Crescent). The crescent grows and becomes more vertical.

Half moon (aka First Quarter) . The crescent is now halfway to full moon.

Waxing Gibbous. We see the moon as convex on both sides, and growing.

Full moon. We see the moon as circular ( again near a conjunction, there may be a lunar eclipse in mid phase)

Waning Gibbous. We see the Moon shrinking again.

Third quarter (the ‘other’ half moon, but now it is the other half of the Moon we can see).

Waning Crescent (shrinking crescent)

‘Waxing’ means growing and ‘Waning’ means shrinking. ‘Gibbous’ means fat, and now the cycle start over with:

Minimal Moon. again

Each phase takes 29.5/8 days. that is 3 days and 16.5 hours

So to answer your question: New Moon to Full Moon is 3 phases. 9 days + 49.5 hours = 11 days and 1.5 hours

The naming of the moon phases is based on human eyesight estimates. That is why I felt a need to introduce the ‘Minimal Moon’ phase to make it Mathematically consistent.

PLEASE MARK THE BRAINILEST, THANK YOU

1 a full moon occurs when the moon moved between orbits so the earth is between the sun and moon.

2. A new moon occurs when the moon orbits around earth and it move between earth and sun.

A circular parallel plate capacitor is constructed with a radius of 0.52 mm, a plate separation of 0.013 mm, and filled with an

olya-2409 [2.1K]

Answer:

289282

Explanation:

r = Radius of plate = 0.52 mm

d = Plate separation = 0.013 mm

A = Area = $\pi r^2$

V = Potential applied = 2 mV

k = Dielectric constant = 40

$\epsilon_0$ = Electric constant = $8.854\times 10^{-12}\ \text{F/m}$

Capacitance is given by

$C=\dfrac{k\epsilon_0A}{d}$

Charge is given by

$Q=CV\\\Rightarrow Q=\dfrac{k\epsilon_0AV}{d}\\\Rightarrow Q=\dfrac{40\times 8.854\times 10^{-12}\times\pi \times (0.52\times 10^{-3})^2\times 2\times 10^{-3}}{0.013\times 10^{-3}}\\\Rightarrow Q=4.6285\times 10^{-14}\ \text{C}$

Number of electron is given by

$n=\dfrac{Q}{e}\\\Rightarrow n=\dfrac{4.6285\times 10^{-14}}{1.6\times10^{-19}}\\\Rightarrow n=289281.25\ \text{electrons}$

The number of charge carriers that will accumulate on this capacitor is approximately 289282.

When vibrational motion in an object increases, which is a true statement?

ss7ja [257]

Hello friend!!

We know that kinetic energy is the energy possessed due to the motion of the object. And we know if the object is in a fast motion then the temperature would be high, whereas if the object is slow in motion then it will have lower temperature. So we know that the kinetic energy is indirectly related to temperature.From our knowledge we can conclude that HIGHER THE TEMPERATURE, HIGHER THE KINETIC ENERGY and LOWER THE TEMPERATURE, LOWER THE KINETIC ENERGY.
Hence, the answer to your question here is,a.kinetic energy, temperature, and thermal energy increase.
Hope it helps!!All the best!!

Two carts, A and B, are connected by a spring and sitting at rest on a track. Cart A has a mass of 0.4 kg and Cart B has a mass

Ilya [14]

Both carts experience the same force but Cart A has a greater speed after the recoil.

The given parameters;

<em>Mass of the cart A = 0.4 kg</em>
<em>Mass of the cart B = 0.8 kg</em>

Apply the principle of conservation of linear momentum to determine the velocity of the carts after collision;

$m_Av_0_A\ + m_Bv_0_B = m_Av_f_A \ + m_Bv_f_B\\\\the \ initial \ velocity \ of \ both \ carts = 0\\\\0.4(0) + 0.8(0) = 0.4v_f_A + 0.8v_f_B\\\\0 = 0.4v_f_A + 0.8v_f_B\\\\0.4v_f_A = -0.8v_f_B\\\\v_f_A= \frac{-0.8 v_f_B}{0.4} \\\\v_f_A = - 2 \ v_f_B \ \ m/s$

According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart A is equal to the force exerted on cart B but in opposite direction.

$F_A = -F_B$

Thus, the correct statement that compares the motion and forces acting on the two carts is "Both carts experience the same force but Cart A has a greater speed after the recoil."
