Answer:
(a) decrease
Explanation:
Viscosity is the resistance which occur to flow of the fluid.
More the inter molecular forces between particles of the liquid, more the viscosity of liquid.
<u>Effect of temperature on viscosity:-</u>
Viscosity decreases with the increase in the temperature as forces among the particles decrease on increasing temperature. The kinetic energy of the particles of the liquid increases causing to move in more random motions and thus weaker inter molecular forces and this offer less resistance to the flow.
<u>Hence, viscosity of the liquids decrease with the increasing temperature.</u>
Velocity adds direction to speed; it is the rate of travel in a particular direction. To calculate velocity, divide distance traveled by the time it took to travel that distance and add direction. If one's position does not change, velocity is zero.
Answer:
The uncertainty in the position of the electron is 
Explanation:
The Heisenberg uncertainty principle is defined as:
≥ 
(1)
Where 
is the uncertainty in momentum, 
is the uncertainty in position and h is the Planck's constant.
The momentum is defined as:
(2)
Therefore, equation 2 can be replaced in equation 1
≥
Since, the mass of the electron is constant, v will be the one with an associated uncertainty.
≥ (3)
Then, can be isolated from equation 3
≥ 
(4)
But 
Hence, the uncertainty in the position of the electron is
