Answer:
Convection is heat transfer through the movement of liquids and gases.
Answer: Find the answer in the explanation
Explanation:
Bohr postulated that :
1.) Electrons revolve in specific circular orbits around the nucleus and these orbits can be represented by the letters K, L, M, N.
2.) Electrons revolving in a particular orbit are in a stationary state. They can neither gain energy nor loose energy. 3.) But if an electron jumps from an higher orbit to a lower orbit it will emit energy in the form of radiations. Also if an electron jumps from lower orbit to a higher orbit it excites and absorbs energy in the form of radiations.
4.) Neil Bohr experimental findings about angular momentum of an electron shows more light on the stability of atom and the line spectrum of hydrogen atom
Answer:
Part a)
Part b)
Part c)
Part d)
Part e)
Part f)
Explanation:
As we know that initial velocity of the ball is given as
Now final velocity of the system is given as
Part a)
now magnitude of initial momentum is given as
Part b)
Change in momentum is given as
Part c)
As we know that average force is defined as the rate of change in momentum
so here we have
Part d)
Magnitude of change in momentum is given as
Part e)
As we know that in 2nd case the force is same as the initial force
so we will have
Part f)
Since this is elastic collision so change in kinetic energy must be ZERO
<u>Answer:</u>
area of point has more pressure.
<u>Explanation:</u>
formula's : pressure = force ÷ area
1st pressure,
200 ÷ 0.2 = 1000 Pa
2nd pressure,
200 ÷ 0.004 = 50000 Pa
<h3>Therefore the pressure on the area of the point is more.</h3>
