We have tons in our atmosphere we can just scoop and bond to the Fe Iron.
Can we synthesize Fe and He together to form a very light but sturdy object?
No. Unless the helium is ionised, which cannot happen under normal conditions.
Your question clearly depends on the angle of launch and the length of the cannon along which acceleration takes place. None of these are given.
I am not going to work it out. I will just leave the rest of the details to you.

He is wrong about earth turning to Venus and he is likely be wrong about AI too.
Either his disability was affecting his judgements and cognitive skills or worse, he deliberately exaggerated stuff so that he could enjoy media spotlight.
hm... my opinion on ai is less dooming than his, on his vision it's like ai may turn into something like skynet and conquer the world like in the terminator movie. My vision is not so dramatic but still bad for mankind, AI and technologies will be taking more and more jobs, making those unemployed useless, no one gonna pay for them to keep doing nothing, so population reduction. And i think the owners of the ai development won't develop it to the point it will get out of their control
Also stephen hawking is an atheist while i believe in God, i'm using the stephen walking opinion to play the atheists' "scientific game" let's put it like that
I know for a fact that AI is increasingly important in weather forecast, especially short term forecast. But it is meant to be a tool for meteorologists. AI is not capable of replacing a human forecaster because personal experience and judgement is not something AI can do.
Some routine and mechanical jobs like restaurant server, could be replaced by AI but it adds value to society in general.

Everyone makes mistakes. Some are fortunate enough to avoid big mistakes but others are not so lucky.
As long as you don’t make the same mistakes twice, you have learnt to become better person.

By the way, in topology pi is usually a symbol for the fundamental group or a projection map. In physics it stands for the canonical momentum operator.
This is one heck of a snow storm. No snow in NYC and only a few inches at most along I-95 corridor. It is a non-event.
Yes, it does snow in March.
It is currently a few degree F above freezing near the northeast coast. Such warm temps are not conducive to large snow accumulations as whatever precip. that falls are dense and wet. May not be snow at all even.
The whole winter has been much warmer than normal with almost no snow in the mid-Atlantic.

Tropical Cyclone Freddy (11S)
Satellite image suggests the system is fairly disorganized, with bursts of irregular cold overcast over the estimated LLC. This is likely due to some mid-level shear. Microwave imagery from approximately 07z shows curved band wrapping more than 75% around the mid-level center that was slightly offset to the north of the low level circulation. Satellite estimates around 12z lie between 55 to 75 kt. The intensity is set at 65 knots.
The cyclone is tracking slowly northwestward under competing steering flow from the building subtropical ridge to the south, and near equatorial ridge stretching southwestward from the Pacific and a slow westward to northwestward track is anticipated during the next couple of days. Global models have generally trended slower with its track over the past couple days and the system is expected to make landfall between 24 to 48 hours. The ECMWF takes the system further inland while the GFS and HWRF shows the system lingering near the coast of South Africa. This discrepancy is related to the difference in strength of the subtropical mid-level ridge to the south and the how the remnant circulation interacts with low-level northerly flow over the Pacific. This forecast is a compromise between the two scenarios, and leans more toward the more eastern solutions based on model trends and expected steering patterns.
Short-term environment is marginal for intensification, with the presence of mid-level shear and a lack of robust outflow being the most significant inhibiting factors. Models do show slight improvement in mid-level moisture prior to landfall and slight intensification is still possible.
After landfall, a slower-than-normal rate of weakening is forecast since part of the cyclone could still be over water, while the center lingers near the coast. An 180 turn in the long term toward the coast could occur as mid-level flow becomes westerly and there is a potential for the remnant low to emerge back over water. However, environmental conditions should be marginal due to moderate westerly shear. Confidence is extremely low.
Intensity forecast:
10/12z: 65 kt (Category 1/East of Mozambique)
11/12z: 65 kt (On the coast)
12/12z: 45 kt (TS)
13/12z: 30 kt (TD)
14/12z: 25 kt
15/12z: 35 kt (TS/Over Mozambique Channel)

Covid boosters are not ordinary vaccines. The side effects of them are being downplayed and everyone should be aware of potential dangers before taking them.
I had a 39.5C fever (supposed to happen to <0.1%) from taking them and a non-negligible population has heart complications. I have had side effects as bad as this from other vaccines.
I am smarter than the entire General BBS combined.
