Answer:
Explanation:
Mass of the Sun, 
The radius of the Sun, 
We need to find the acceleration due to gravity on the surface of the Sun. It is given by the formula as follows :
So, the value of acceleration due to gravity on the Sun is 
.
Which of the following are characteristics of noble gases?
✅
- An inert gas is one that does not undergo chemical reactions. The noble gases have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why they are said to be inert.
✅
- Noble gases are the least reactive of all elements. This is because they already have the desired eight total 's' and 'p' electrons in their outermost (highest) energy level.
Milliliter centiliter deciliter liter dekaliter hectoliter kiloliter
All related by 10's every move to the right is 10x larger than the one to its left
Since deciliter is two steps away from milliliter it is 10 x 10 or 100 times as large.
If the question is meant to be a trick then the answer is 99x larger.
It should read "A deciliter is how many milliliters" ofr "a milliliter is how much of a deciliter?"
Once you say larger than you could be confusing subtraction with multiplication. How much larger than 30 is 3? Answer is clearly 27. How many times as large as 3 is 30? Answer is clearly 20. How many times larger than 3 is 30? Hmmmm? Which one of the two does he mean?
I am sure your teacher meant you to consider multiplication, but just in case, I included the "trick" answer.
Answer:
= 2.49 × 10³J
Explanation:
Total rotational kinetic energy K = nRT
R = 8.134 J/mol.K
n = 1 mol
T = 300 K
K = 1 × 8.314 × 300
= 2.49 × 10³J
Classically and Newtonianly, it's the sum of the chemical energy if any,
the electrical energy if any, the thermal energy if any, and the mechanical
energy consisting of potential and kinetic energy if any.
The mechanical energy, consisting of potential and kinetic energy if any, is
0.001 x [ (acceleration of gravity x height) + (1/2) (speed)² ] .
But I've got a sneaky hunch that you're not talking about any of these.
You want to know how much [ <em><u>mc</u>² </em>] there is in 1 gram of mass. No prob.
E = m c² = (0.001) x (3 x 10⁸)² = <em>9 x 10¹³ joules</em>
That's the energy that a 1,000-watt toaster uses
in <em>2,852 years</em> of continuous toasting.
