Answer: hello options related to your question is missing attached below is the missing part of your question
answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )
Explanation:
When the Charge is first, Furthest away and second and closest to the source charge. <em>The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source </em><em>when Furthest away the bond with charge will be less effective </em>
D.) It is an "Element".
[ Element cannot be separated by any means ]
Hope this helps!
C. Magnetism
Very few minerals are magnetic, while streak hardness and specific gravity can be used to identify lots of minerals
Mainly it belongs in the deciduous forest biome. The U.S also includes the desert, tundra, and coniferous forest biomes.
Put this under 'Geography' next time.
Hope this helps!

The vertical position of the rock is given by:
where
h=75 m is the initial height
v0=20 m/s is the initial vertical velocity
g=9.81 m/s^2 is the acceleration due to gravity
The problem asks to find the time t at which the rock hits the ground, so the time t at which y(t)=0, so the equation above becomes:
Which has two solutions:
t=-2.37 s
t=6.45 s
The first solution is a negative time so it has no physical meaning, therefore the correct answer is t=6.45 s.
