Answer:
+16 J
Explanation:
We can solve the problem by using the 1st law of thermodynamics:
where
is the change of the internal energy of the system
Q is the heat (positive if supplied to the system, negative if dissipated by the system)
W is the work done (positive if done by the system, negative if done by the surroundings on the system)
In this case we have:
Q = -12 J is the heat dissipated by the system
W = -28 J is the work done ON the system
Substituting into the equation, we find the change in internal energy of the system:
False because when the training higher there is less oxygen
Answer:
Common stock
Explanation:
Common stock is also regarded to as shares in which dividends are paid to the holders according to how profitable the organization is.
Common stock is a type of equity security and it is also the least considered in the case of bankruptcy due to its variability and the probability of stockholders not getting anything because of the debtor being insolvent.
Answer:
Satellites don't fall from the sky because they are orbiting Earth. Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity--combined with the satellite's momentum from its launch into space--cause the satellite go into orbit above Earth, instead of falling back down to the groundv
Explanation:
Answer: A nanometer-size carrier could be designed to bring the chemotherapy drugs only to cancer cells.
Explanation:
The problem with chemotherapy as noted by the text above, is that the drugs used target both living and cancer cells and kills them regardless.
The solution therefore, would be to find a way to ensure that chemotherapy targeted only the cancer cells.
One way to do that is to design a nanometer sized carrier that would take the drugs to cancer cells alone so that they would kill only the canerous cells and leave the healthy ones.
