Answer:
-100 kJ
Explanation:
We can solve this problem by applying the first law of thermodynamics, which states that:
where:
is the change in internal energy of a system
Q is the heat absorbed/released by the system (it is positive if absorbed by the system, negative if released by the system)
W is the work done by the system (it is positive if done by the system, negative if done on the system)
For the system in this problem we have:
W = +147 kJ is the work done by the system
Q = +47 kJ is the heat absorbed by the system
So , its change in internal energy is:
Answer:
diffrent types of maks and modles
Explanation:
<h3><u>Given :-</u></h3>
<h3><u>To Find </u><u>:</u><u>-</u></h3>
<h3><u>Solution:- </u></h3>
When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed
So, Volume of object
= Increased Volume - Initial volume
= > 187.5 -175
= > 12.5 ml
Since 1 ml = 1 cm³ we can write
12.5 ml = 12.5 cm³
Now,
Putting Values -
>> The density of the material is 2.6 g/cm³
Answer:
Option C. To have two copies of each chromosomes.
Explanation:
DNA replication also increase genetic diversity because, new strand of DNA formed is different form original one.
