The only believable lie is one based in truth.

Science is based on the scientific method,.. a man made philosophy.

Any theory is an assumption based on a limited pool of facts.

all facts are merely if then statements, and very case sensitive.

No one has disproved a single Christian belief. They merely say that there is no reason to look in that direction, to the scientists. Then say Christians believe in stoning, and ignore the reasons for stoning,.. to all of the common public. (yet, God never endorsed stoning, the only time God was in government was when he had tribal leaders. before and after tribal leaders, God wasn't in the business of teaching people new ideas. When the people asked for a king,.. God warned them and walked away.)

A jumbo jet starting from rest needs to attain a speed of 350 km/h on the runway to take off. Can this plane use a 1-km long runway if it is to accelerate at the rate of 2.67 m/s2 (meter per second squared)? Please explain why. Thanks.

The longest bicycle in the workld was built in New Zealand in 1988 it is more than 20 m in length, has a mass of 3.4 x 10² kg, and can be ridden by four people at a time. Supposed four people are riding the bike south-east when they realize that the street truns and that the bike won't make it around the corner. All four riders jump off the bike at the same time with the same velocity (9.0 km/h to the northwest, as measured relative to Earth.) The bicylce continues to travel forward with the velocity of 28 km/h to the southeast. If the combined mass of the riders is 2.5 x 10² kg, what is the velocity of the bicycle and riders immediately before the riders escape?

i think its asking for v(initial), right?

does the change of direction affect the conservation of momentum??

the formula is m1x v1 (initial) + m2 x v2 (initial) = m1x v1 (final) + m2 x v2 (final)

please sovle and explain a little

I am a one man band new at bringing attention to innovation in base load electric generation.

The idea behind the generator arose from Steam requiring 550Dc heat to reach a pressure of 140 Bar the force required a rotate a 350 megawatt steam turbine.

There be many other gasses that reach that pressure at far less heat, but unlike steam they don’t require cooling water to condense back into a liquid.

“Einstein “was the first with this when he invented the Ammonia Fridge, now commonly known as the Gas fridge.

Some active gasses need only air temperature to supply pressure enough to power a 350 Megawatt turbine.

add, subtract, multiply and divide two 9's and two 1's to equal 10.

meaning, if you filled in the blanks with +, -, x, /,
9_9_1_1
how would you get ten?

you can rearrange the numbers if necessary.

Use the reaction: () are subscripts
2Fe(2)O3 + 3C -> 4Fe + 3CO(2)


Using 1000g C, how many grams of Fe can be produced?

What is the theoretical yield of Fe in a reaction with 7.00g Fe(2)O(3) and 1.25g C?

What amount of the reactant in excess will remain at the end of the reaction? Give answer in grams.

i believe that this earth has supernatural things but i just wanted to no what you think. Do you think theres a god?

I do believe in science but what scientist say now that there was a big boom and the galaxy, earth was created i pretty much think thats stupid.

thanks for the people who answer
