Answer:
Height covered after crossing window top = 0.75 m
Explanation:
In the question,
The height of the window pane = 1.8 m
Time for which the flowerpot is in view = 0.66 s
So,
The time for which it was in view while going up is = 0.33 s
Time for which it was in view while going down = 0.33 s
So,
Let us say,
The initial velocity of the flowerpot = u m/s
So,
Using the equation of the motion,
So,
Velocity at the top of the window pane is given by,
Now,
Let us say the height to which the flowerpot goes after crossing the window pane is = h
So,
Using the equation of motion,
Therefore, the height covered by the flowerpot after window is = 0.75 m
Answer:
Resultant = 13km
Direction = 67.38° East of North
Explanation:
Given the following :
5km North ; 12km East
Resultant Displacement (r) :
r² = 5² + 12²
r² = 25 + 144
r² = 169
r = √169
r = 13
Direction:
Tangent = opposite / Adjacent
Tanθ = opposite / Adjacent
Opposite = 12 ; adjacent = 5
Tanθ = (12/5)
Tanθ = 2.4
θ = tan^-1(2.4)
θ = 67.38° east of north
A solid can diffuse into a liquid, but a solid cannot diffuse into another solid.
A solid can diffuse into both a liquid and another solid.
I believe that your current answers are correct, but I also think that you could add:
Water flowing downhill a region.
This is as when water flows downhill a region, it will carry with it an abundant amount of particles which will continue to flow with the water until it finally disperses or ends up in one location.
We can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
<h3>What is torque</h3>
The torque experienced by an object a given position is the product of the applied force and the perpendicular distance of the object.
When 5 kg mass is at 2 m on the left, another 5 kg at 2 m on the right will balance it.
<h3>Position of 10 kg mass on the right</h3>
Apply principle of moment
<h3>Net torque</h3>
<h3>Position of the 20 kg mass</h3>
<h3>Net torque</h3>
Thus, we can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
