3. What is the best way to help with<br> mining problem in the future?
marusya05 [52]

Answer:

1) Mining companies have an impressive track record for delivering continuous improvements in safety and risk governance standards. We have no doubt that the professionalism and expertise present within the industry will ensure that any new and emerging risk challenges are dealt with in an equally determined fashion.

2) Insurers have recognized the approach and achievements of mining companies in identifying, mitigating and retaining their risks. Many mining companies have close and longstanding relationships with their insurers built through regular dialogue with mining company executives and visits to mining sites and processing facilities.

3) This document should be of value to any organization involved in this ever-evolving industry.

4) The very nature of mining natural resources means that many businesses will have operations in some of the most remote and inhospitable areas in the world and very often coupled with a high susceptibility to natural catastrophe.

5) In addition to the traditional risk factors, the mining industry now faces an even wider range of challenges. Factors such as climate change, new technologies, economic uncertainties and secure supply of key consumables like electricity, water, gas and other fuels are all difficult to predict and bring additional complications to securing appropriate balance sheet protection.

A ball is rolled twice across the same level laboratory table and allowed to roll off the table and strike the floor. In each tr
schepotkina [342]
By definition we know that the distance is equal to the speed by time
 d = v * t
 Clearing the time we have
 t = d / v
 for conservation of energy. we have to for every attempt
 mgh = (1/2) mv ^ 2
 Clearing the speed
 v = Root (2gh)
 Then, substituting
 t = d / v
 t = h / (Root (2gh)
 We conclude that the time is the same since it depends on the height of the table to the floor.

Consider the vector b⃗ with magnitude 4.00 m at an angle 23.5∘ north of east. what is the x component bx of this vector?
Aleksandr [31]

Answer:

3.67 m

Explanation:

A physical quantity is said to be vector quantity if it need a magnitude as well as direction for complete explanation.

It makes an angle 23.5 degree from positive X axis.

So, it's component along X axis is given by

bx = B Cos theta

bx = 4 × Cos 23.5

bx = 3.67 m

Find the magnitude of the sum of these two vectors:​
sukhopar [10]

Answer:

Explanation:

You can decompose those vectors into their components in x and y direction. For the first vector:

\vec{r}_{1}=r_{1}\cos 30\hat{i}+r_{1}\sin 30\hat{j}=3.14(\frac{1}{2}\sqrt{3}\hat{i}+\frac{1}{2}\hat{j})=1.57\sqrt{3}\hat{i}+1.57\hat{j}

For the second vector:

\vec{r}_{2}=r_{2}\cos 60\hat{i}-r_{2}\sin60 \hat{j}=1.355\hat{i}-1.355\sqrt{3}\hat{j}

The sum of two vectors will be:

\vec{r}=\vec{r}_{1}+\vec{r}_{2}=(1.57\sqrt{3}+1.355)\hat{i}+(1.57-1.355\sqrt{3})\hat{j}\approx 4.0711\hat{i}-0.77415\hat{j}

The magnitude of the sum of two vectors is:

r=\sqrt{(4.0711)^{2}+(-0.77415)^{2}}\approx 4.14 meter
