<span>when the gravitational forces and air resistance equalize on an object that is falling toward the earth and the object stops accelerating its called TERMINAL VELOCITY</span>
Answer:
Cy and Di
Explanation:
We cannot tell exactly where the right end of the mirror is, but if we assume it is short of allowing Ed and Fred to see each other, we have the following:
Cy can see Cy and everyone to the right
Fred can see Di and everyone to the left
The only two that can see all of Cy, Di, Ed, and Fred are Cy and Di.
_____
If the mirror extends far enough to the right for Ed to see Fred, then all of Cy, Di, and Ed can see the four folks of interest.

they're both properties of water. both involve the "sticking" property of H2O .</span><span>
cohesion is "sticking" together (water sticking to water) and adhesios is water</span><span>
</span>
"sticking" to something else. They are both important to life processes.
<span>In chemistry, adhesion refers
to the tendency of unlike molecules to bond with one another, while
cohesion refers to the attractive force between molecules of the same
type. Surface tension, which is an essential property of water, illustrates the relationship between adhesion and cohesion.</span>
When a dielectric material is inserted between two plates of capacitor that are connected to a battery, you would observe that both the charge and the capacitance of the capacitor would change. This is due to the dielectric material which is able to transmit electric force.
Answer:
correct option is E
power lens is - 1.667 D
Explanation:
Given data
infinity = 60 cm
to find out
power lens
solution
we know here infinity v = -60 cm because object at infinity
and we take u = - infinity
so we know that
1/f = 1/v - 1/u
1/f = 1 / -60 - 1 / -infinity
so
1/f = - 1/60
f = - 60 cm = 0.60 m
and we know power of lens = 1/f
so here
power = 1 / -0.60
power = - 1.667 D
so correct option is E
power lens is - 1.667 D
