Answer:
1/3
Explanation:
We can solve the problem by using the lens equation:

where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
Here we have a divering lens, so the focal length must be taken as negative (-f). Moreover, we know that the object is placed at a distance of twice the focal length, so

So we can find q from the equation:

Now we can find the magnification of the image, given by:

Answer:
Electronic Health Record (EHR)
Explanation:
An Electronic Health Record is basically a digital equivalent of a patient's medical record. They are extremely useful because they provide a concise and accurate history of all of the patient's former treatments, exams and ilnesses, which help in optimization of the treatment process by eliminating extra steps like retaking exams and reducing the odds of medical errors.
Answer:

Explanation:
First of all let's define the specific molar heat capacity.
(1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system
Now, we can find n with the molar mass (M) the mass of the compound (m).
Using (1) we have:
