A retaining wall is 5m long (into the plane of the paper), and it is supported by an anchor rod. The soil it supports has a weig

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

---------------------

Available data:

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

Four forces are acting on an object one force is pulling two Newtons to the left the second force is pulling 2 Newton’s up the t

Sedaia [141]

Answer:

Explanation:

1. The net force acting on an object is the combination of all of the individual forces acting on it.

2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.

3. If two forces act on an object in the same direction, the net force is the sum of the two forces.

A radiographer in a hospital is preparing a sample of technetium-99. Name two protective measures she should be to ensure she is

Hitman42 [59]

Answer: There are many precautionary measures which is to be taken care of while handling technetium-99.

Explanation:

There is a proper separated area for the handling of the 99Tc and all the containers are properly labelled for the use of technetium-99 only.

While working on it, the person is not allowed to eat or drink anything.

Use of gloves, glasses and other preventive measure is also very important when handling radioactive materials.

Try to maintain a proper distance throughout the experiment.
