Answer:
24.70 yrs
Explanation:
Using length contraction formula
where v = 0.9910c, Lo = 42.2 light years
L = L₀ = 42.2 = 5.649 yr
to= = 5.649 c.yr / 0.9910c = 5.70yrs
the biological age of Capella = 19 + 5.70 yr = 24.70 yrs
Answer:
Speed of the runner during video interval is 6.49 m/s
Explanation:
According to the problem,
Number of frames recorded by camera in 1 second = 50
Time takes by camera to record 1 frame = (1/50) s
Time taken by camera to record 77 frames, t = s
Distance covered by the runner during the video recording, d = 10 m
Speed, v =
Substitute the values of d and t in the above equation.
v =
v = 6.49 m/s
The atoms furthest from the nucleus
Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the star
m = Mass of object at a distance r
r = Radius = 25 km
N = 14 rev/s
The gravitational force of will balance the centripetal acceleration
Velocity is given by
The mass of the neutron star is
When a proton is fired without any positive or negative forces within the grid the proton will pass straight through the grid without changing its path. A proton is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron. If isolated a single proton would have a mass of 1.673 × 106-27 kg which is slightly less than that of a neutron.
