True - large amounts of alcohol can lead to blackouts which in some cases can involve amnesia
Answer:
Engine A is able to accelerate a car faster.
Explanation:
Answer:
No it will not make to the top of the hill
Explanation:
From the question we are told that
The velocity is 
The height of the hill is 
Generally from the law of energy conservation we have that
The kinetic energy of the pluck at the level position = The potential energy of the pluck at the maximum height the pluck can get to
So

=> 
=> 
=> 
Given that the maximum height which the pluck can get to at this speed given in the question is less than the height of the hill then conclusion will be that the pluck will not make it to the top of the hill
Answer:
Blank One: I'm not certain but I'd assume it's either sound or energy.
Blank Two: Louder
Explanation:
volume is controlled by how much energy is put in an area per a unit of time, so the more energy in one area for a unit of time, the louder the sound will come out.
Sorry I couldn't give the best explanation!
Answer:
The value of current through the rod becomes half

Explanation:
As per Ohm's law we know that the current through a resistor is given as

here we know that

here we know that the length of the cylinder is L and area is A so the value of current through the rod is given as

now we have change the length of the conductor to twice of initial value and rest all parameters will remain the same
so we will have

now from above two equations we have

so new current will become
