Answer:
The refraction of light at the surface of water makes ponds and swimming pools appear shallower than they really are.
Explanation:
so its just the refraction of light at the surface
Answer:
12N
Explanation:
Force acting on any body is equal to mass of body multiplied by acceleration produced in the body.
Its formula is
F = M*a
where F is the force acting on body
M is the mass of the body
a is the acceleration produced in the body
Unit of force is Newton represented by N
1 N is force acting on body of mass 1 kg which produces acceleration of 1m/s^2.
_____________________________________
Given
a = 0.50 m/s^2
M = 24 kg
therefore
F = 24*0.5 = 12 N
Thus, magnitude of the boy's pushing force is 12 N.
Answer:
Conduction
Explanation:
Conduction. When a substance is heated, its particles gain internal energy and move more vigorously. The particles bump into nearby particles and make them vibrate more. This passes internal energy through the substance by conduction , from the hot end to the cold end.
