The answer is going to be C
Answer:
The larger person will have to get a larger parachute. The answer is D
Explanation:
If the smaller person does nothing, the larger person subsequently accelerate for more time and with larger terminal velocity. In this case the person needs to do something so as to reduce the terminal velocity and can also effectively raise the air resistance. For this reason the person should get a bigger parachute. The air resistance in the opened parachute overwhelms the downward force of the gravity. Whereas the net force as well as the acceleration of the person is upward. The bigger parachute has the ability to grab the greater force. If the parachute, dragging force works in the opposite to that of the force of the gravity, hence the drag force slows the parachute decrease as they fall.
Answer:
Cl
Explanation:
Electronegativity is the ability of an electron to attract electrons.
Now, due to the fact that halogens need just one more electron to become stable in their outermost shell, it means all halogens are electronegative.
However, the smaller the atomic number, the bigger the charge density and thus the more electronegative.
Thus, it is the halogen element with the highest atomic number further down the periodic table that will have the least electro negativity and thus require highest amount of energy to attract other electrons.
Thus, since chlorine (Cl) has the least atomic number of 17, then it means that it will be the one that will easily accept the electrons the most from other elements. Therefore the process of transferring electrons from potassium to chlorine will take the least amount of energy.
Answer:
Explanation:
Energy needed = mass * temperature difference * specific heat
= 4.37 * (27.5-25) * 0.24
= 4.37 * 2.5 * 0.24
= 2.622J
