Answer:
(C) passive state.
Explanation:
The earth pressure is the pressure exerted by the soil on the shoring system. They are three types of earth pressure which are:
a) Rest state: In this state, the retaining wall is stationary, this makes the lateral stress to be zero.
b) Active state: In this state, the wall moves away from the back fill, this leads to an internal resistance. Hence the active earth pressure is less than earth pressure at rest
c) Passive state: In this state the wall is pushed towards the back fill, this leads to shearing resistance. Hence, the passive earth pressure is greater than earth pressure at rest
a) Question Completion:
INPUT HOURS OF LABOR
Country Cookies Milk
Atlantis 2 hours 1 hour
Neverland 4 hours 1 hour
Answer:
1. Atlantis has the absolute advantage in the production of cookies.
2. No country has the absolute advantage in the production of milk.
Explanation:
Absolute advantage refers to superior production capability. It is determined when a country, for example, has the ability to produce a particular good or service at lower cost or more efficiently (i.e. with less resources) than the other country. In the scenario above, Atlantis has an absolute advantage in the production of cookies because it can produce the same quantity of cookies using 2 labor hours that Neverland can produce using 4 labor hours. But for the production of milk, Atlantis and Neverland share the same comparative advantage less they can use less labor hours to produce milk than they can produce cookies.
Answer:
the nation will suffer terrible consequences
Explanation:
I did that and got it right
Answer:
extrusive,
Explanation:
lava exlodes outwards, making it extrusive and not intrusive.
Explanation:
Velocity
Velocity is the rate of distance covered in a direction. To calculate the velocity of an object, you divide the change of distance of the object (initial to final) by the change in time(initial to final). It is similar to speed, but involves direction which speed does not. We found the velocity of all the moving objects in or machine, such as the marbles, race car, and the wheel and axel.
Acceleration
Acceleration is the speeding up or slowing down of an object. It is calculated by dividing the change in velocity by the change in time (a=Δv/Δt). Acceleration's unit of measurement is m/s^2. We found the acceleration of all the objects that are falling, speeding up, and slowing down; such as the dominos falling, the car speeding up due to gravity, and the marbles slowing down after hitting the mixing bowl.
Speed can vary from machine to machine.
Force
Force is a push or pull on an object. To find the force of an object, calculate the product of the mass of the object and the acceleration of the object. Force is measured in newtons. We were able to find the force of all of the objects on our machine, because even if an object is not moving, it is still exerting a force due to the acceleration of gravity (9.8 m/s^2).
