Rigel´s surface temperature is 11,000 Kelvin

And here the source:

Przybilla, N. (2010). "Mixing of CNO-cycled matter in massive stars". Astronomy and Astrophysics. 517: A38. arXiv:1005.2278. Bibcode:2010A&A...517A..38P. doi:10.1051/0004-6361/201014164.

An elevator whose mass is m = 400 kilograms is supported by a cable. A frictional force of f = 80 newtons is applied to the elev
Dmitry_Shevchenko [17]

Answer:

3924 N

5124 N

4004 N

2884 N

4004 N

Explanation:

m = Mass of elevator = 400 kg

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration

f = Friction force = 80 N

When the elevator is stationary only the acceleration due to gravity will be acting on it

Tension

T=mg\\\Rightarrow T=400\times 9.81\\\Rightarrow T=3924\ N

The tension is 3924 N

The balanced force equation would be

T-mg-f=ma\\\Rightarrow T=ma+mg+f\\\Rightarrow T=400\times 2.8+400\times 9.81+80\\\Rightarrow T=5124\ N

The tension is 5124 N

When velocity is constant acceleration is zero

T-mg-f=0\\\Rightarrow T=mg+f\\\Rightarrow T=400\times 9.81+80\\\Rightarrow T=4004\ N

The tension is 4004 N

T-mg-f=-ma\\\Rightarrow T=-ma+mg+f\\\Rightarrow T=-400\times 2.8+400\times 9.81+80\\\Rightarrow T=2884\ N

The tension would be 2884 N

When velocity is constant acceleration is zero

T-mg-f=0\\\Rightarrow T=mg+f\\\Rightarrow T=400\times 9.81+80\\\Rightarrow T=4004\ N

The tension is 4004 N

Starting from rest, a runner accelerates to 10 m/s in 5 s. What is the acceleration of the runner?
ELEN [110]
A=vf-vi / time

* vi here is zero as the runner started from rest*
so
a= 10-0/5 which equals 2 m/s^2

Which equipment would help you separate a liquid mixture by distillation?
anzhelika [568]
Distillation is a process in many laboratories for the purpose of separating and/or purifying components of a liquid mixture. The distillation apparatus used consists of three major parts: <span>distillation flask - to heat the mixture and volatilize the components, a condenser to cool the vapors back to liquid state, and a collection vessel.  The apparatus is typically made of glass and therefore subject to breakage.</span> <span>All components of the distillation apparatus should be protected to a stable stand or rack to avoid it from falling over.</span>
