The person is standing on the floor of the elevator, and he isn't
floating up or smashing through the floor.
So the person's acceleration is exactly the same as the elevator's
acceleration.
Now, Newton's second law of motion says:
F = M · a
(the net force on the person) = (the person's mass) x (his acceleration)
Net force = (80 kg) x (0.5 m/s²)
= 40 newtons .
homo. It is a mixture because it has different things in it. If they are distributed homogeneously ...
Answer:
18.5 cm
Explanation:
From;
1/u + 1/v = 1/f
Where;
u= object distance = 86cm
image height = 23 cm
Radius of curvature = 37 cm
The radius of curvature (r) is the radius of the sphere of which the mirror forms a part.
Focal length (f) = radius of curvature (r)/2 = 37cm/2 = 18.5 cm
Therefore, the focal length of the mirror is 18.5 cm
Answer:
Solar activity can affect satellite orbits, communication satellites, and the local power grids. It can also impact our spacecraft throughout the solar system, especially orbiters or landers on surfaces without an atmosphere.
