<span>The career that is most concerned with the study of radioactive isotopes is chemistry. You need to have passed AP chemistry to actually deal with the isotopes. In a quick reference, isotopes are when the atom has difference amount of neutrons, making the atomic mass differ.</span>
The answer is D. Products are formed from reactants by the breaking and forming of new bonds.
A) 50 cm
B) 10000 cm/s
Explanation
Step 1
A)
If you know the distance between nodes and antinodes then use this equation:
then, let
now, replace to find the wavelength
so, the wavelength is
A) 50 cm
Step 2
The speed of a wave can be found using the equation
or velocity = wavelength x frequency,
then,let
replace and evaluate
so
B) 10000 cm/s
I hope this helps you
Answer:
the human brain is responsible for involuntary activities, such as regulating heartbeat, breathing, and blinking. Although the brain controls both voluntary and involuntary activities, different regions of the brain are devoted to each type of task.
Both involuntary and voluntary actions are controlled by the same parts of the brain. Hindbrain and midbrain control involuntary actions like salivation, vomiting, etc. All the body's voluntary actions are controlled by the motor cortex in the frontal lobe of the cerebrum.
