I heard researchers succesfuly created leydig cells in the laboratory.Is the treatment feasible.Can leydig cells be transplanted externally via an injection or transplantation?How much would it cost?...
For the two of you who may care, my ongoing personal quest to understand the latest UK Covid figures and make predictions about the future continues. Things are naturally complicated by the fact that...
I drag a mass m=21 kg in a straight line, along a horizontal surface, a distance D=23 m . I drag it at constant speed v=0.90 m.s−1 in a straight line using a horizontal force. The coefficients of...
A rubber band has mass m=0.30 g and a spring constant k=15 N.m−1 . I stretch it by 5.0 cm (which in this case doubles its length). Assume the rubber band behaves as a Hooke's law spring. Assume that,...
As is usually the case, the answers are "possibly" and "fairly, maybe?". But this is also an interesting video to see how statistical analysis can be used to even try to answer the question....
Bit of a weird question - but if | was transported back to around 4,000 years after this asteroid, would the earth have settled down, and could I survive.
A machine gun fires bullets, each with mass m = 55 , gm=55 g at a speed of u = 450 m.s u=450 m.s −1 . The gun fires 5.05.0 bullets per second. Let's use it as a rocket engine. What thrust does it...
[#751] Exploding A mass breaks suddenly into two parts, masses MM and mm, with speeds VV and vv respectively and carrying a total kinetic energy KK. If \frac{M}{m} = R = 4.2 m M =R=4.2, what...
