HELP PLEASE! I have some homework for my 9th grade physical science class and it's due Monday, I already completed 1/2 of it, if

you can answer one or more that'll be really helpful, ty! If a question does not make sense please let me know, each of the pages contain a small paragraph that may be needed to complete the question. (p.s. if u do answer a question, please identify the page it is on and what number it is, tysm)
page 1
3: The symbol for one of the elements is derived from its German name, wolfram. What is the English name for this element?

page 2
1. What limitation is placed on electrons in the Bohr model of the atom?

2. When the light from a gas is passed through a prism, why is there only a certain number of lines rather than a continuous spectrum?

3. How is the series of lines emitted by a gas similar to a fingerprint?

4. Explain how scientists can use the pattern of lines from an unknown gas to identify what elements are contained in the gas?

page 3
1. what is ONE important difference between the Greek theory of atoms and Dalton's atomic theory?

2. what is the significance of the invention of the STM?

3. explain how an STM creates an image of the atoms on the surface of a material

Page 1: #3

Wolfram is known as Tungsten in English (Tungsten's symbol is a W).

Page 2: #1

I think the limitation is that the electrons in the Bohr model are only in certain energy levels and that they orbit the nucleus.

It's been a while since I was in a physical science class so I'm not sure about the rest but I wish you luck! I hope this helps a little bit!

In a paragraph, contrast the characteristics between anorexia and bulimia
FinnZ [79.3K]
Bulimia nervosa is similar in many ways because the individual is obsessed with their weight and wants to continuously lose weight to achieve their idea of a 'perfect' body shape. But with bulimia, there are periods of binging and purging. This means that the individual with bulimia may go through a period where they eat an excessive amount of food and then purge by using exercise, medications or vomiting to get rid of the food.

What is the gravity force between two stars with mass of 5,000,000 kg and 1,000,000 kg if the distance between them is 100 m
Luda [366]

Answer:

0.0334N

Explanation:

Given parameters:

M1  = 5 x 10⁶kg

M2  = 1 x 10⁶kg

Distance  = 100m

Unknown:

Gravitational force  = ?

Solution:

To solve this problem, we use the Newton's law of universal gravitation.

     Fg  = \frac{G m1 m2}{r^{2} }  

G is the universal gravitation constant

m is the mass

r is the distance

         Fg  = \frac{6.67 x 10^{-11} x 5 x 10^{6}  x 1 x 10^{6} }{100^{2} }   = 0.0334N
