A: The charge of a proton is positive, a neutron is neutral and an electron is negative. The protons and neutrons are found in the nucules while the electrons orbit the nucules in their given energy levels.
True,when you turn the volume up on your television , you're actually turning up the amplitude<span>!

The answer is yes!
Hydrogen gas is generated as part of the charging process of lead/acid cell batteries. If the hydrogen gas acculates in large concentrations in a building or room or a box, an electrical spark or other ignition source will cause the hydrogen to burn in a rapid reaction causing an possible explosion.
A good example of a hydrogen gas explosion and fire is the "Hindenburg" disaster of the old flying blimps or zepplins.
Answer:
Explanation:
= Initial diameter = 4 cm
= Initial velocity = 1 m/s
= Final diameter = 7.8 m
= Final velocity
= Area = 
From the continuity equation we get
The speed of water at the second floor is .
Need to draw it first.....
but there is no option here to draw .. why?
anyway , here the car is going with a uniform velocity..
so the acceleration of the car=0, a=0
so resistive force on the car=component along the inclined plane of the weight of the car=mg*cos(90-15)=960*9.8*cos 75=?
