Solnce55 [7]

Answer:

explanation of this effect  is  the photoelectric effect

Explanation:

Let's describe the process, when light of large wavelength falls, this implies a small energy, according to Planck's equation

           E = h f = \frac{h \ c}{ \lambda}

the energy of the photons is not enough to carry out an electronic transition between two states of the material, when we decrease the wavelength (the energy of the photons increases), the point is reached where the energy of the beam is equal to some energy of a transition, by which the electrons are promoted and since we can see a certain charge, as the atoms are neutral, some electrons must be removed from the material, this is represented in the macroscopic case as the work function of the material, consequently a unbalanced load that is what we can measure.

When we increase the lightning intensity, what we do is that we increase the number of photons and if each photon can remove an electron, by removing the electrons the difference between it and the positive charge (fixed in the nuclei) increases.

We can analyze the interaction of the photon and the electron as a particular collision.

The explanation of this effect was made by Einstein in his explained of the photoelectric effect

Why do animal cells not need central vacuoles? Help A.S.A.P! Please!
Tamiku [17]

Answer:

This is because animals do not need to store as much water as plants.

Explanation:

Animals generally have smaller vacuoles than plants. Plants have large vacuoles that can occupy a large portion of their cell (up to 30 percent). The major function of the vacuole is to store water and maintain cell turgidity and pressure against the cell wall.

Animals on the other hand do not have a rigid cell wall, rather, they have a flexible cell membrane. As a result of this, they do not need to store water in vacuoles.

A 2000-kg railway freight car coasts at 4.4 m/s underneath a grain terminal, which dumps grain directly down into the freight ca
ruslelena [56]

Answer:

933. 3kg

Explanation:

We are given that

Mass,m=2000 kg

Initial speed,u=4.4 m/s

We have to find the maximum mass of grain if the speed of loaded freight car must not go below 3.0 m/s.

Final speed,v=3 m/s

By conservation of momentum

Initial momentum=Final momentum

mu=m'v

Substitute the values

2000\times 4.4=m'(3)

m'=\frac{2000\times 4.4}{3}

m'=2.93\times 10^3 kg

Mass of freight loaded car=2933.3 kg

Mass of grains=2933.3-2000=933.3 kg

Hence, the maximum  mass of grains that it can accept=933.3 kg
