The x -component of the object's acceleration is 2 m/s².

<h3>What's the resultant force along x- direction?</h3>

Forces along x axis direction are as follows

4N along +x axis, so it's taken as +4 N
2N along -x axis , so it's taken as -2N.

Resultant force along x direction = 4N - 2N = 2 N which is along + ve x direction.

<h3>What's the acceleration along x axis direction?</h3>

As per Newton's second law, Force = mass × acceleration of the object
Force along x axis= mass × acceleration along x axis= 2N
Acceleration = 2/ mass = 2/1 = 2 m/s²

Thus, we can conclude that the acceleration along x axis is 2 m/s².

The heat flow into the sample in the segment ________ will yield the value of the heat of fusion of this substance

SpyIntel [72]

The heat flows into the sample in the segment <u> BC </u> will yield the value of the heat of fusion of this substance.

<h3>Heat of fusion:</h3>

The heat of the fusion of water is unusually high. The amount of heat required to convert 1 g of solid into a liquid while maintaining the same temperature is known as the heat of fusion. It is a latent heat as well and is occasionally referred to as the latent heat of fusion. Since water only freezes at a single temperature (0 °C), it only has one value, which is 79.71 cal/g, or the rounded amount of 80 cal/g.

In order to control frost, water fuses at a high temperature. The water used for irrigation is frequently consistently above freezing when it is extracted from the ground.

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

vekshin1

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
