Answer:
6010.457N
Explanation:
Centripetal acceleration = a= V²/R
At a radius of 3.6m and velocity of 16.12m/s,
Acceleration is
a = 16.12²/ 3.6 = 72.182 m/s²
Force = Mass (m) * Acceleration (a)
36 = m * 72.182
m = 36/72.182
At breaking point
Radius = 0.468 m and Velocity = 75.1 m/s
a = V²/R = 75.1²/0.468
a = 12051.3 m/s
F = Mass(m) * Acceleration (a)
F = m * 12051.3
m = F/ 12051.3
Settings the ratio of mass equal
m = m
=> 36/72.182 = F/12051.3
F = 12051.3 * 36/72.182
F = 6010.457N
Answer:
Speed of the alpha particle is
Explanation:
We have given charge on alpha particle
Mass of the alpha particle
Potential difference
We have to find the speed of the alpha particle
From energy conservation we know that
Answer: yes it can be prevented
Explanation:
The sensation of weightlessness that astronauts experience seems to make their tasks almost effortless. However, as Newton's third law of motion suggests, working in space can be physically demanding.
As he tightens the bolt, he is rotating in the direction opposite to the bolt
It is possible if the handhold is designed in three dimensional motion where the astronaut motion will be the uplimb motion with the mass centre of hand move along circular helix trajectory
Angular momentum is conserved astronaut motion is conserved when net external torque is Zero.
Answer:
The focal length of a lens is refers to the distance from the center of the lens to the principal foci.
