Answer:
1. the difference between a series circuit and parallel are if a bulb goes out in a series circuit all go out and in a parallel if one goes out all the others stay on.
2. the function of a switch is to determine if the circuit is closed or open and how is stays on.
Explanation:
Hello There!
The resistance of a conductor depends on all of the following except mass.
Mass wouldn't affect the resistance in any way.

The book's vertical position in the air is
where 
. It reaches the ground when 
, at a time 
such that
So it takes the book 4 seconds to reach the bottom. The given initial velocity is irrelevant since it only has a horizontal component; vertically, the book is starting from rest.
Answer:
Explanation:
There are three basic ways to increase the likelihood of safely dropping an egg:
Slow down the descent speed.
Parachutes are an obvious method for slowing the decent speed, as long as the design includes a way to keep the parachute open.
Cushion the egg so that something other than the egg itself absorbs the impact of landing.
The largest end of the egg has an area of air trapped between the egg's two membranes. This air space forms when the contents of the egg cool and contract after the egg is laid. It accounts for the crater you often see at the end of a hard-cooked egg. Upon impact the heavier spherical yolk continues moving towards the ground. The compression of the airspace acts like an air bag for the eggs' valuable contents. Building an artificial cushioning device will also help absorb the impact of landing.

Orient the egg so that it lands on the strongest part of the shell.
The arch structure at either end of the egg is stronger than its sides. Pressure is distributed down (or up) the arches so that less pressure acts on any one point. Orienting the arch downwards will increase the egg's survival.
Hope this helps you
