Answer:
There would be a pressure drop in the direction of the higher opening. This will force air to move in from the lower opening and force it to leave through the higher opening. This will create a convectional movement of air, cooling and ventilating the tunnel.
Explanation:
This is in accordance with bernoulli's law of fluid flow which states that the pressure exerted by a moving fluid is lesser than it would exert if it were at rest.
Answer
given,
Wavelength of the light = 574 nm
distance from the screen = 2.38 m
distance between the second diffraction minimum and the central maximum = 1.82 cm = 0.0182 m
a) Angle of diffraction for the second minimal
θ =
θ =
θ = 0.438°
b) width of slit d is given by
d = 1.5 x 10⁻⁴
Answer:
18 m
Explanation:
G = Gravitational constant
m = Mass of planet =
= Density of planet
V = Volume of planet assuming it is a sphere =
r = Radius of planet
Acceleration due to gravity on a planet is given by
So,
Density of other planet =
Radius of other planet =
Since the person is jumping up the acceleration due to gravity will be negative.
From kinematic equations we have
On the other planet
The man can jump a height of 18 m on the other planet.
Work=applied Force x distance
= 1275 x 26
=33150 Joules
