Solution:
a) We know acceleration due to gravity, g = GM/r²
Differential change, dg/dr = -2GM/r³
Here, r = 50*Rh = 50*2GM/c² = 100GM/c
²
My height, h=dr = 1.7 m
Difference in gravitational acceleration between my head and my feet, dg = -10 m/s²
or, dg/dr = -10/1.7 = -2GM/(100GM/c²)³
or, 5.9*100³*G²*M² = 2c⁶
or, M = 0.59*c³/(1000G) = 2.39*1032 kg = [(2.39*1032)/(1.99*1030 )]Ms = 120*Ms
Mass of black hole which we can tolerate at the given distance is 120 time the mass of Sun.
b) This limit an upper limit ,we can tolerate smaller masses only.
D. distance
A light-year is the distance light would travel in 1 year.
Answer:
what is this a riddle lol it breaks when he either jumps or lands
Explanation:
Thermal energy is the sum of the energy of all the particles. That means that large objects at a low temperature (with slower moving particles) can have more energy than small objects with high temperatures (faster moving particles). The faster the particles, the more energy they can transfer.
