Emma S. Bellows is a person whose initials are ESB. Her husband, George Wesley Bellows was an artist. When he died, many of his lithographs and drawings were unsigned. Emma signed them with his name, then added her initials.
The word "Astronaut" is spelled as A-S-T-R-O-N-A-U-T.
Tangential velocity squared is GMs/r and velocity v =29814m/s and the centripetal acceleration is v2/r= 5.928 E-3 m/s2
The formula to calculate the acceleration due to gravity at a certain altitude h above Earth's surface is g' = g * (R / (R + h))^2, where g is the acceleration due to gravity at the Earth's surface (approximately 9.81 m/s^2), R is the radius of the Earth (approximately 6371 km), and h is the altitude. In this case, h = 1.47 * R, so substituting the values into the formula gives g' = 5.64 m/s^2.
At a height of 6400 km above the Earth's surface, the acceleration due to gravity can be calculated using the formula ( g' = g_0 \left( \frac{R}{R + h} \right)^2 ), where ( g_0 ) is the acceleration of gravity at the Earth's surface (approximately 9.81 m/s²), ( R ) is the Earth's radius (about 6400 km), and ( h ) is the height above the surface. Substituting the values, the effective gravity at this height is approximately 2.45 m/s². This demonstrates that gravity decreases with altitude, being significantly weaker at that height compared to the surface.
"What is the answer to this riddle you live above a star but do not burn i have eleven neighbours but they never turn My initials are pq and r and sometimes s What are you?" Take a look on your mobile phone keypad, in particular the number 7 ;-)
m = pqr/s Multiply both sides by s: ms = pqr Divide both sides by pq: ms/pq = r
If PQ and RS are two 2-digit numbers, then PQ * RS = 100*P*R + 10*P*S + 10*Q*R + Q*S

Suppose x and y are two rational number.Then x = p/q and y = r/s where p, q, r and s are integers, with q and s being non-zero. Then x - y = p/q - r/s = pq/qs - qr/qs = (pq - rs)/qs. The signs of x and y do not matter, in so far as their signs will be used to determine the signs of p,q, r and s.

It is most probably Sleigh Ride.
You do it the obvious way. Take p, q in Q, the rationals By definition, we can write p = m/n and q = r/s where m, r are integers, n and s are natural. we define pq (p times q) = (mr)/(ns) p/q = pq^-1 where q^-1 denotes q's multiplicative inverse s/r Remark: you cannot divide by 0 here because 1) 0 have no multiplicative inverse 2) if r = 0. s/r is undefined.
