Answer:
The value is
Explanation:
From the question we are told that
The saturation density of air is
The temperature for this saturation density to occur
The relative humidity at this temperature is
Generally the relative humidity is mathematically represented as
Here H represents humidity
=>
=>
=>
Answer:
a)
b)
c)
Explanation:
Given that
Length =L
Mass = m
Force on elemental part
dF= dm ω² r
dm = m/L dr
dF= ω² r m/L dr
By integrating from r to L
Velocity V
Answer:
<h3>The answer is 0.67 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.67 m/s²</h3>
Hope this helps you
Answer:
1. Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.
2. Well, Pluto was most likely difficult to find, because of its small size and great distance from Earth.
Answer:
8.2 m/s²
Explanation:
m = mass of the block
μ = Coefficient of kinetic friction = 0.17
= Normal force on the block by the ramp
= kinetic frictional force
Force equation perpendicular to ramp surface is given as
Kinetic frictional force is given as
Force equation parallel to ramp surface is given as
m/s²
