Develop a product by using principles of science to encounter environment related problems

Oxana [17]

It is because we are, this is the first time in human history, where we have technology and science is widely accepted, without being ridiculed by religious figures.
Science can provide us with enough detailed knowledge about nature to solve and prevent environmental problems. ... It is possible to prevent pollution in the future and develop 'clean' industrial processes that have no environmental impacts.
Develop a product by using principles of science to encounter environment related problems
It is currently believed that science and technology can provide effective solutions to most, if not all, environmental problems facing western industrial societies. ... It can therefore be concluded that science and technology have only very limited potential in solving current and future environmental problems.
Ways Technology is Helping the Environment
We use Less Energy to do Things.
Energy Production is Becoming Cleaner.
Clean Energy Systems are More Effective.
Food Production is Becoming More Eco-friendly
Recycling is Reducing Waste and Pollution.
Cities are Becoming Less Polluted
We Are Becoming More Aware Of Our Effect On The Planet
We Can Share More Knowledge And Understanding

The kinetic energy of a 10.3 g golf ball traveling at 48.0 m/s is

Svetach [21]

To work out the kinetic energy of an object, you use the formula:

E = 0.5 x (mass) x (velocity)^2

One important thing, though. The units MUST be consistent. Mass needs to be in kilograms, and velocity in metres per second.

To convert the mass form grams to kilograms, we need to divide it by 1000, getting 0.0103 kg. Since the velocity is already in the units we need, we can just plug the numbers into the equation to get:

E = 0.5 x (0.0103 kg) x (48.0)^2 = 11.8656 J = 11.9 J, to 3 significant figures

Hope I helped! xx

Will strontium bromide and potassium sulfate give a precipitate

antiseptic1488 [7]

Answer:- Yes, strontum bromide and potassium sulfate gives a precipitate of strontium sulfate.

Explanations:- As per the solubility rules, all compounds of alkali metals are soluble.

Sulfate of most of the alkaline earth metals like Ca, Ba and Sr are insoluble.

A double displacement reaction takes place when strontium bromide and potassium sulfate are mixed and a precipitate of strontium sulfate is formed:

$Sr(Br)_2(aq)+K_2SO_4(aq)\rightarrow 2KBr(aq)+SrSO_4(s)$

Note: (aq) stands for aqueous and (s) stands for solid and here it's precipitate.
