Answer:
Pressure at P point is given as
Explanation:
As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe
here we know that
L = 4 cm
r = 1 mm
Q = flow rate
now we have
Volume is the scientific word...
Answer:
ve = 8.06 x 10^5 m/s
vp = 1.882 x 10^4 m/s
Explanation:
K = 1.85 eV = 1.85 x 1.6 x 10^-19 J = 2.96 x 10^-19 J
me = 9.11 ✕ 10^-31 kg,
mp = 1.67 ✕ 10^-27 kg
Let the speed of electron is ve and the proton is vp.
For electron :
K = 1/2 me x ve^2
2.96 x 10^-19 = 0.5 x 9.11 x 10^-31 x ve^2
ve^2 = 6.498 x 10^11
ve = 8.06 x 10^5 m/s
For proton:
K = 1/2 mp x vp^2
2.96 x 10^-19 = 0.5 x 1.67 x 10^-27 x vp^2
vp^2 = 3.5449 x 10^8
vp = 1.882 x 10^4 m/s
Answer:
The Energy possessed by a body by virtue of its position or state is called Potential energy.
Mathematically potential energy can be written as,
Potential energy = mgh
Where 'm' represents mass of the body, 'g' represents gravity of the earth and 'h' represents height of body. Potential energy depends on the height, higher the hight from the surface of the earth, maximum will be the potential energy.
