Answer:
The modern instruments or we can say the different levels of telescopes are used to explore and study the distant galaxies. i.e the Hubble telescope is out there providing the data regarding the different properties of the celestial entities which in other case is not visible to the human naked eye.
Explanation:
- Scientists and research workers are in constant search for more answers as they explore the universe and implement the laws of physics on the celestial entities. But, most of the objects inside the universe are not visible to human naked eye, as they are far from sight and thus more advanced form of instruments like the x-ray, optical, and light telescopes are used to determine the different properties of the celestial entities inside the universe. 
- As, these telescopes includes the most recent "Hubble telescope", which is out there inside the space to explore the universe and more over the galaxies by subjecting them with x-rays and then provide us with a very rough but valid results to study the distant galaxies. 
 
        
             
        
        
        
Answer:
Explanation:
kinetic energy required = 1.80 MeV 
= 1.8 x 10⁶ x 1.6 x 10⁻¹⁹ J 
= 2.88 x 10⁻¹³ J 
If v be the velocity of proton 
1/2 x mass of proton x v² = 2.88 x 10⁻¹³ 
= .5 x 1.67 x 10⁻²⁷ x v² = 2.88 x 10⁻¹³ 
v² = 3.45 x 10¹⁴
v = 1.86 x 10⁷ m /s 
If V be the potential difference required 
V x e = kinetic energy . where e is charge on proton .
V x 1.6 x 10⁻¹⁹ = 2.88 x 10⁻¹³
V = 1.8 x 10⁶ volt . 
 
        
             
        
        
        
<span>coefficient
       
Let's look at the 3 possibilities and see what they are for </span>3H₂O₂ coefficient - This is used to indicate that multiple molecules are used for the formula. In 3H₂O₂ that indicates that we are talking about 3 molecules of H₂O₂ subscript - This is a small number set in a smaller font and placed low to the elements. It indicates the number of each type of atom in the compound. For the formula 3H₂O₂ there are 2 subscripts. Both of them being the number "2" set small and low just after the letters H and O. Those subscripts indicate that there are 2 hydrogen and 2 oxygen atoms per molecule.
element - This is the abbreviation for the elements used in the compound. In <span>3H₂O₂</span> there are 2 different elements. H to indicate hydrogen, and O to indicate oxygen.
        
             
        
        
        
Answer:
Explanation:
In first case we are interested in one time 6 in six rolls 
Thus probability = number of chances required/Total chances 
= 1/6 
Similarly in the second case probability = 2/12 = 1/6 
In the same way in last case probability = 100/600 = 1/6
The probability is the same . Thus all the cases has equal chances
