The elements which have similar behavior are Barium, strontium and beryllium.
Explanation:
The mathematical and proportional relationship between mL and 
said us that 
is equivalent to 1mL.
If the density is considered as the amount of mass per unit volume we will have to
here,
m = mass
V = Volume
Replacing we have that
As 
we have that the density in g/mL is,
In the first case:
when we heat any gas, the Kinetic Energy of the molecules increases, making it collide more frequently with the surface, increasing the pressure
more collisions with the surface means more force applied on it, which would push the piston harder than before, moving it outwards.
In the second case:
since the molecules inside the beaker have no way to escape, they would keep compressing the more you push the beaker downwards.
since there is the same number of molecules and lesser volume to cover, the molecules will start colliding with the surfaces more frequently, which would resist the downward force.
<em>another way to think about it is to imagine yourself where the trapped air is. you would be happy when the room is spacious but if the wall starts moving towards you, you would resist the change by your body because you need space to exist. making it harder for the wall to move.</em>
<em>pushing the beaker downwards will keep getting harder and harder the more you push until you reach a point where the molecules will be completely compact. applying even more force forces the molecules to enter water, removing the air that was resisting it all and making you able to get the beaker in water.</em>
Third case:
just like in the first case, the heated air will apply force on the surface, including the cork. which would pop off when enough force is applied.
Answer:
64.20m
Explanation:
As we can see from the image I have attached below, the route that the chipanzee makes forms a right triangle. In this case, the shortest distance is represented by x in the image, which is the hypotenuse. To find this value we use the Pythagorean theorem which is the following.
where a and b are the length of the two sides and c is the length of the hypotenuse (x). Therefore, we can plug in the values of the image and solve for x
2,601 + 1,521 = 
4,122 = ... square root both sides
64.20 = x
Finally, we see that the shortest distance is 64.20m
