Covalent bond occurs due to chemical reaction
Answer:
Assume two identical cans filled with two types of soup having same mass are rolling down on an inclined plane in same conditions. In terms of inertia different types of soup will indicate different viscosity. The higher viscosity fillings indicates more part of the soup mass is rotating together with the can’s body. This means that for the can with lower viscosity soup has a lower moment of inertia and the can with higher viscosity has higher moment of inertia while the same gravity makes them to roll.
incline angle = θ ; can's mass = m ; Radius of the can's = R , Angular acceleration for Can 1 = α1 ; Angular acceleration for Can 2 = α2
T1 = Inertia of Can with high viscosity soup
T2 = Inertia of Can with low viscosity soup
M1 rolling moment of Can 1
M2 rolling moment of Can 2
equation is given by
T1*α1 = M1 - (a)
T2*α2 = M2 - (b)
M1 = M2 = m*g*R*sin(θ). (c)
as assumed T1 > T2
from the three equation (a), (b) & (c)
the α2 > α1
Angular acceleration of Can 2 is higher than Can 1. Already stated that Can 1 has more viscous soup as compared to Can 2.
As it's name suggests it is a liquid with a very low freezing point. When added to the water in your car's cooling system it keeps it from freezing in cold weather. If the water in your cooling system freezes the radiator and associated piping would crack.
Knowing that the greatest horizontal pressure is the pressure made by the material on the wall -considering for that the total height of the wall-, then P = 4.375 t/m
---------------------
<u />
<u>Available data</u>:
- The wall is 5m long into the plane ⇒ H
- The soil density is 1.4 metric tonnes per cubic metre ⇒ γ
- K = 0.25 ⇒ Coefficient of earth pressure. Depends on the angle.
From this information, we need to calculate the greatest horizontal pressure.
Horizontal pressure refers to the force made by the supported soil on the retaining wall that tends to deflect the wall outward.
We can calculate horizontal pressure at different heights from the top. And since we need to calculate the greatest horizontal pressure, we need to consider the total height that equals the wall height, H.
To do it, we will use the following formula, and replace the terms.
P = [ k
γ H² ] / 2
P = [ 0.25 x 1.4 t/m³ x 5m² ] / 2
P = 8.75/2
P = 4.375 t/m
