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>
Answer:
<h3>The answer is 19,800 J</h3>
Explanation:
The work done by an object can be found by using the formula
<h3>workdone = force × distance</h3>
From the question
force = 120 N
distance = 165 m
We have
work done = 120 × 165
We have the final answer as
<h3>19,800 J</h3>
Hope this helps you
Answer: the mercury will be 1155.678mm above the reference mark
Explanation:
Detailed explanation and calculation is shown in the image below
The pressure at a point on a sloping surface with a tank filled with liquid depends on the slope of the surface because the elevation is a factor here. The force that is a factor too is dependent on the angle of elevation. Force is equal to weight times sine angle.
Answer:
140.04 m from the stop.
Explanation:
We can divide the motion in two parts:
First, we have an uniformly accelerated motion, using the following formula we calculate the distance traveled in this part:
In the second part, the car decelerates, but we don't know the value of this deceleration. We have to calculate the time spend in the first part, in order to know the time spend on second part:
Recall that total time is 15 s
Now, we calculate the deceleration:
Finally, we find the distance traveled in the second part. In this way, we can know how far does the car travel.
