Answer:
a. True
Explanation:
This statement is true, and incredibly important. Every material used in construction has a breaking point and a deformation point. A breaking point is the amount of stress or weight material can handle before it completely gives out and breaks while the deformation point is the point in which it begins to bend or change its shape. Therefore, it is incredibly important to know both this information and the amount of force that will be exerted onto the materials. Mainly because if the amount of force exceeds these points it will cause the material to deform/break which can cause the entire structure to collapse and either injure or kill many people.
Answer:
Explanation:
The orographic effect occurs when air masses are forced to flow over high topography. As air rises over mountains, it cools and water vapor condenses. As a result, it is common for rain to be concentrated on the windward side of mountains, and for rainfall to increase with elevation in the direction of storm tracks.
Answer:
388.5J
Explanation:
Given parameters:
Weight = 70N
Height = 5.55m
Unknown:
Gravitational potential energy at the top of the ladder = ?
Solution:
The gravitational potential energy is the energy due to the position of the body.
Gravitational potential energy = Weight x height
So;
Gravitational potential energy = 70 x 5.55 = 388.5J
