What type of charge is acquired when a rubber is rubbed with a fur

Rus_ich [418]

Answer:

The triboelectic charging process (a.k.a., charging by friction) results in a transfer of electrons between the two objects that are rubbed together. Rubber has a much greater attraction for electrons than animal fur.

In Mendel’s day, many people thought that offspring inherited a blend of their parents’ traits. For example, they thought that a

Fantom [35]

Answer:

Explanation:In Mendel's time, many people thought that offspring inherited a combination of traits from their parents. For example, they thought that an animal with white fur and an animal with black fur would produce pups with gray fur. This is called the theory of combined inheritance. How did Mendel show that the combination theory was wrong?

A 35-year-old patent clerk needs glasses of 50-cm focal length to read patent applications that he holds 25 cm from his eyes. Fi

Natali5045456 [20]

Answer:

28.57 cm

Explanation:

We are given that

Focal length, $f=50 cm$

Distance of application from his eyes,s=40 cm

$\frac{1}{s}+\frac{1}{s'}=\frac{1}{f}$

$\frac{1}{40}+\frac{1}{s'}=\frac{1}{50}$

$\frac{1}{s'}=\frac{1}{50}-\frac{1}{40}=\frac{4-5}{200}$

$s'=\frac{200}{-1}=-200 cm$

s=25 cm

Substitute the values

$\frac{1}{25}-\frac{1}{200}=\frac{1}{f'}$

$\frac{8-1}{200}=\frac{1}{f'}$

$\frac{1}{f'}=\frac{7}{200}$

$f'=\frac{200}{7}=28.57 cm$

What about the atomic model shown below was shown incorrect?

charle [14.2K]

In an atom there are neutrons, protons and electrons. the number of protons is the atomic number . the number of neutron is the atomic mass minus atomic number. the number of electrons is the number of protons.protons and neutrons are located in the middle of the atom. and in the first ring (the ring closest to the middle) it can hold 2 electrons if there is more than two it will go to the second ring (the second ring from the middle of the atom) in the second ring it can hold eight if there is more than eight it will go to the third ring from the middle and the forth ring from the middle can hold 12 atoms . the symbol for proton = +
the symbol for neutron = it has no symbols
the symbol of electron = - .
