Answer:

b)  line spectra

Explanation:

 The model of the atom as given by Rutherford was modified by Bohr. According to Rutherford's model, the electrons that orbit the nucleus electromagnetic radiation. As a result they lose energy and had to collapse into the nucleus, thereby making the atom unstable.

Bohr corrected that by proving that electrons revolve around the nucleus only in certain fixed orbits, with a specific energy. They can jump from one to another and lose or gain energy by emitting or absorbing energy in that process.

Electron cloud is the region where the electrons are most likely to occur. This was proposed by Schrodinger.

Two positive charges of 6.0 x 10^-6 C are separated by 0.50 m. Calculate the force of electrical attraction
SpyIntel [72]

Answer:

Force between two charges is given as 1.296 N

Explanation:

As we know that the two charges will attract or repel each other when they are placed near to each other

Here we know that electrostatic force is given as

F = \frac{kq_1 q_2}{r^2}

here we have

q_1 = q_2 = 6 \times 10^{-6} C

distance between two charges is given as

r = 0.50 m

so we have

F = \frac{(9\times 10^9)(6 \times 10^{-6})^2}{0.50^2}

F = 1.296 N

The speed of sound in ice, water, and steam is shown. What best explains the speed of sound in different states of matter?
Marina86 [1]

The speed of sound is greater in ice (4000 m/s), then in water (1500 m/s), then in air (340 m/s). The explanation for this is the differente state of the matter in the three cases.

In fact, sound waves travel faster in solids (like ice), then in liquids (like water), then in gases (like air). This is because the speed of the sound wave depends on the density of the medium: the greater the density, the faster the sound wave. This can be easily understood by thinking at how a sound wave propagates: a sound wave is a vibration of molecules, which is transmitted throughout the medium by collision of the molecules. Therefore, the smaller the spacing between the molecules (such as in solids), the more efficient is the propagation, and so the sound wave is faster. On the contrary, there is a large spacing between molecules in gases (such as in the air), so there are less collisions between the molecules and so the wave is not transmitted efficiently, and so it has less velocity.

Tasya [4]

Answer: Create a hypothesis

Explanation:

From the information given, information has been gathered and the identification to ascertain if there's a change. Then, an hypothesis has to be created in order to know what the problem is.

One has to carry out some research in order to know what went wrong and should also validate the hypothesis by consulting with ones peers. By doing this, the most likely causes of the issues will be gotten.

A motorcyclist drives around a bend with a 20 m radius, with a constant velocity of 3 m/s. The motorcyclist and the motorcycle h
Pavel [41]

Answer:

a=0.45\ m/s^2

Explanation:

Given that,

The radius of a bend, r = 20 m

Velocity of motorcyclist, v = 3 m/s

The combined mass of motorcyclist and the motorcycle is 50 kg

We need to find the motorcyclist’s centripetal acceleration. The formula used to find the centripetal acceleration is given by :

a=\dfrac{v^2}{r}\\\\a=\dfrac{(3)^2}{20}\\\\a=0.45\ m/s^2

So, the acceleration of the motorcyclist is 0.45\ m/s^2.
