Answer:
The power of the mirror is -17.24 diopter.
Explanation:
Magnification of an image,m = 
Distance of the object from the mirror = u = 29.0 cm
Distance of an image from the mirror = v
Magnification = 





Focal length of mirror = -5.8 cm =-0.058 m
Power of the lens = P


Answer:

Explanation:
From the free-body diagram for the car, we have that the normal force has a vertical component and a horizontal component, and this component act as the centripetal force on the car:

Solving N from (2) and replacing in (1):

The centripetal acceleration is given by:

Replacing and solving for v:

Answer:
oxygen gains two electron to attain electron configuration like neon. Oe-²
Explanation:
Electric force depends on the charge and the strength of the electric field. The equation that relates the three:
F = Eq where q is the charge and E is the electric field strength.
When a liquid is heated, the molecules gain kinetic energy. As the liquid begins to boil they have enough energy to break the intermolecular attractions between their neighbors. This happens first at the surface before the volume below has enough energy to boil. Thus you see high energy water molecules escaping from the surface as mist.
