According to Newton’s Second Law, for equilibrium, the net force and the net torque acting must both add up to zero The geometry of the sticks are locked in place by the weight of the bottle creating tension, the centre of gravity is behind the edge 1/🧵

2/That centre of gravity is low and pushed behind the edge by the vertical stick at an angle, this is why the bottle can move side to side but not back and forth

calling this setup "in equilibrium" is begging the question it's not it's glue

Here's the deputy leader of the Nationals confirming their party is 100% committed to the country-wrecking net-zero. That means net-zero farms, net-zero trucks, net-zero red meat, net-zero diesel. The Nationals are the party of destroying the bush.

Off the foul … net? 🤔 DYK the Rogers Centre is the only MLB stadium to uniquely feature a net in place of a traditional pole?

Right now Net Zero is getting the blame for everything. The madly ironic truth is that the series of blackouts of the last few years have had nothing to do with net zero and everything to do with extreme weather, driven by the climate crisis - and net zero is how we stop that getting worse. Stopping net zero is not the answer to stopping extreme weather induced blackouts….Jeez…

Physicist Brian Greene demonstrates gravity in the simplest way possible using a bottle full of water. When the bottle is held still water streams out through the holes because gravity creates pressure inside. But the instant he drops the bottle the leaking stops completely. Bottle and water fall together at the same rate so the water becomes weightless relative to the bottle. It is a perfect demonstration of Einstein’s idea that gravity and acceleration are deeply connected. What feels like weight is often just the result of the frame you are in.

Net zero is an attack on working Australians. Australia had some of the lowest electricity prices in the world, but now it has some of the highest due to net zero. The IPA’s Daniel Wild caught up with Barnaby Joyce MP at Parliament House to discuss his bill to abolish net zero.

BHP drank the net zero kool-aid, and now thousands of workers have been put out of work. Rick Wilson's electorate of O’Connor is ground zero for net zero, and it's Aussie families here in the Kalgoorlie region and across the country that are paying the price.

Albanese has no mandate for Net Zero, for he won the election through deception. Albanese deceived Australians about the cost of Net Zero. He lied by claiming that under Net Zero, electricity prices would be cheaper, when in fact, Net Zero is causing electricity prices to skyrocket. There should be a national plebiscite on Net Zero after an honest debate about its true costs. Intermittent renewables are to an electricity grid what COVID injections are to the human body—the more you put into the system, the greater the damage you do.

Senator Alex Antic is leading the charge to force the Opposition to cast off the shackles of Net Zero. The SA Liberals motion to dump Net Zero has resonated throughout the country with other divisions due to do the same!! The importance of ‘drill baby drill is it drops the price of everything. Whereas solar and wind is expensive, unreliable and actually destroys the environment. Time to make Australia great again!!

A demonstration of static electricity illustrates how charged objects interact. Coulomb’s law provides the mathematical framework for describing the electric force between these charges. Formulated in the 18th century by French physicist Charles-Augustin de Coulomb, the law parallels Isaac Newton’s law of gravity in its structure and significance.

This is a brand new package of Jimmy Dean bacon The marked weight on the package is 12 ounces If you take the unopened package and put it directly on a scale the weight is only 10.6 ounces, and that’s with the package I looked up the law. In the United States the marked net weight on bacon packages must reflect only the weight of the bacon itself, excluding the packaging Under FDA rules the packaging must be excluded We are being robbed blind

Plans for Britain to reach Net Zero by phasing out the use of fossil fuels are 'irrational' and 'doomed to fail'. That's according to former Labour leader Sir Tony Blair. @louisajamesitv has the latest.

So Michaelia is now speaking out against the madness of Net Zero. Better late than never. However, it would have been nice to have had her support five years ago when I was one of the few in the Coalition prepared to take up the fight and argue the case against Net Zero. Instead, Michaelia was sitting in cabinet, changing the policy which we took to the 2019 election, and signing off on the Liberal Party adopting Net Zero for 2050.

The government has been hiding the cost of Net Zero from you for DECADES. The climate agenda is driving up Aussie energy costs and crippling industries. It’s about global control and wealth transfer to billionaires at the expense of everyday Australians. One Nation says NO to the climate change agenda and NO to Net Zero.

This is a brand new Heinz yellow mustard just purchased from Walmart You can see the seal is unbroken, it’s brand new and placed directly on a zeroed out scale It’s supposed to weigh 1 pound 4 ounces. It only weighs 1 pound 0.7 ounces and that’s with the bottle Keep in mind, this is with the packaging The label “1 lb 4 oz” refers to the net weight of the mustard inside, not the total weight of the bottle plus contents The plastic squeeze bottle itself should not be included in the marked weight on the bottle, meaning the mustard is actually missing a significant amount more mustard We are being robbed blind in America

“Net zero is going to have absolutely no effect on the climate whatsoever. The vast majority of the globe in both population and GDP are not participating in it, So why are we doing this to ourselves?” Wonderful speech by Barnaby Joyce. 👏🏽

Frequent private jet passenger, John Kerry, admits that destruction of the farming industry is essential to achieving 'Net Zero': "Agriculture contributes about 33% of all the emissions of the world. And we can’t get to net zero—we don’t get this job done—unless agriculture is front and centre as part of the solution." "You just can’t continue to both warm the planet, while also expecting to feed it. It doesn’t work. So we have to reduce emissions from the food system."
