A. planets do not affect birth defects
A) 350 J
- The initial internal energy of the cup is
- The final internal energy of the cup is

According to the first law of thermodynamics:

where
Q is the heat absorbed by the system
W is the work done on the system
The work done on the system in this case is 0, so we can rewrite the equation as

And so we find the heat transferred

B) IN the cup
Explanation:
in this situation, we see that the internal energy of the cup increases. The internal energy of an object/substance is proportional to its temperature, so it is a measure of the average kinetic energy of the molecules of the object/substance. Therefore, in this case, the temperature (and the energy of the molecules of the substance) has increased: this means that heat has been transferred INTO the system from the environment (the heat came from the sun).
Answer:
Below
Explanation:
Incredible amounts of fossil fuels are used to mine for materials, buil and transport electric vehicles
Electric vehicles use electricity to charge their batteries. Most electricity is generated using fossil fuels such as natural gas and coal .
Answer:
renewable, you can keep growing corn for it. more fossil fuel can be made by nature but it takes way too long to be considered renewable
Answer:
A. Both spheres land at the same time.
Explanation:
The horizontal motion doesn't affect the vertical motion. Since the two spheres have the same initial vertical velocity and same initial height, they land at the same time.
