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.
Density is mass divides by volume, so
89.6g / 10cm^3 =8.96g /cm^3
*cm^3 is a standard unit of volume*
Answer:
-963.93 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The acceleration of Superman would be -963.93 m/s² from Lois' perspective
<span>The term "displacement" includes a change of position or change in an innate characteristic.
The first option would have someone travel in an L-shape, which definitely is a change in position from the starting point.
The second option of Ferris wheel with the same entrance and exit does not involve overall displacement since a person would return to the same place they began.
The third option of walking around the block does not involve overall displacement since, again, the person would return to the same place they began.
The fourth option of an escalator ride does involve overall displacement because a person would finish their journey in a different vertical location from where they started.
The last option does not involve overall displacement because one lap around a track will return you to the same place you began.</span>
Answer:
The radius of the curve that Car 2 travels on is 380 meters.
Explanation:
Speed of car 1, 
Radius of the circular arc, 
Car 2 has twice the speed of Car 1, 
We need to find the radius of the curve that Car 2 travels on have to be in order for both cars to have the same centripetal acceleration. We know that the centripetal acceleration is given by :
According to given condition,
On solving we get :
So, the radius of the curve that Car 2 travels on is 380 meters. Hence, this is the required solution.
