because not all substances react the same to temperature changes. If you heat a metal and an organic substance and you turn the temperature up, the organic substance like water will react (boil) while most metals need higher temperature to react.

A series of three direct shear tests has been conducted on a certain saturated soil. Each test was performed on a 2.375-inch dia
Pachacha [2.7K]

Answer:

Go to explaination for the details of the answer.

Explanation:

Angle of friction (friction angle) is a measure of the ability of a unit of rock or soil to withstand a shear stress. It is the angle (φ), measured between the normal force (N) and resultant force (R), that is attained when failure just occurs in response to a shearing stress (S).

The cohesion intercept is a used when we want to describe the shear strength soils. The definition is mainly derived from the Mohr-Coulomb failure criterion and it is used to describe the non-frictional part of the shear resistance which is independent of the normal stress.

Please check attachment to Determine the friction angle and cohesion intercept.

The net negative charge flowing through a device varies as q(t) = 2.2 t2 C. Find the current through the device at t = 0, 0.5, a
Leni [432]

Answer:

The current at t= 0 sec, is 0 A

The current at t= 0.5 sec, is 2.2 A

The current at t= 1 sec, is 4.4 A

Explanation:

Given that

q(t) = 2.2 t²

We know that:- the change in the charge w.r.t. time is known as current. So,

I=\dfrac{dq}{dt}

q(t) = 2.2 t²

\dfrac{dq}{dt}= 4.4 t

I= 4.4 t

1.

t = 0 s :

I = 4.4 x 0 = 0 A

<u>Therefore, the current at t= 0 sec, is 0 A</u>

2 .

t= 0.5 s :

I = 4.4 x 0.5 = 2.2 A

<u>Therefore, the current at t= 0.5 sec, is 2.2 A</u>

3.

t= 1 s

I = 4.4 x 1 =4.4 A

<u>Therefore, the current at t= 1 sec, is 4.4 A</u>
