Answer:
A
Explanation:
option A is correct
the best example of elastic collision among the following is collision between two billiard balls. In collision of two billiard balls the energy lost is very little approximately zero. hence we can say that the kinetic energy is conserved. since, the kinetic energy is conserved we can say that the collision is elastic
The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as sun's rays hit them directly.
Therefore, the answer is C.
Answer:
P = 101292.8
Explanation:
Use
Pressure p = H D g
H = height ( in metric)
D = density ( in metric )
g = gravity
So
H = 76 cm = 0.76 m
D = 13600 kg/m3
And g = 9.8
P = HDg
= 0.76× 13600×9.8
= 101292.8 pascal
Or = 1.012928 × 10^5
