Answer:
5.014x10^23 atoms
Explanation:
first start with given over 1 so 15 over 1 then multiply that by 1 over 18.01528 and then multiply it by 6.022x10^23 over 1 which then gives you the answear hope this helps god bless
Answer:
I feel that "The Mesosaurus could not swim between the continents in the open ocean, so the fossils
show that the continents must have been together in the past." Is the best answer.
Explanation:
Because this is a true statement and even scientists belive this is true.
Ummm...
WHat is this? What do you want us to do??
<u>Answer:</u>
The temperature of the water is 70°C
<u>Explanation:</u>
Partial pressure of helium gas = 526 mmHg
Total pressure inside the jar= 760 mmHg
Suppose partial pressure of helium gas is 
and partial pressure of water is
And total pressure is 
As we know
Hence
Putting the values
In bar,
= 0.312 bar
Now according to the steam table
With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C
Answer:
= 1375 joules
Explanation:
- Kinetic energy refers to the energy possessed by an object or a body when in motion.
- It is calculated by halving the product of the mass of the body and the square of its velocity.
That is;
Kinetic energy = 0.5 × Mass × velocity²
Therefore, in this case;
Kinetic energy of linebacker = 0.5 × 110 Kg × 5²
= 1375 Joules
Therefore; the kinetic energy of the line backer is 1375 joules
