Answer:
the object falls faster and faster until it strikes the ground.
Explanation:
-When objects are in free fall, the only force acting on these objects is gravity. Free fall thus occurs when an object is dropped in air that experiences no air resistance.
-Freely falling objects will fall with same acceleration due to the force of gravity and thus the object falls faster and faster as the speed increases, the net force acting on the objects is weight, their weight-to-mass ratios are always the same, their acceleration is g which is as a result of the force of gravity.
Answer:- oxygen.
Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration, .
The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.
So, the electrically neutral atom for the given electron configuration is oxygen.
B. 0.9 <span>
</span>D.Light intensity has no effect on whether electrons are emitted or not.
and
A. X=1.9eV,Y=0.2eV
I already took the gizmo so I know these are right. The first one I got wrong b/c there was no graph and the last one I didn't understand. Basically for the last one you calculate the work function for the metals and find their difference.
Hope this helps.
Answer:
no one answered this so ima use it for points. im really sorry.
What do you think it is? I'll give you a hint, it's either A or C. Don't guess, just try.
