Answer:
3 m/sec(squared)
Explanation:
a=change in velocity/time
a=v-u/t
a=36-0=36/12
a=3m/s(squared)
The sum of all forces on an object is called the "net" force on it.
For an object at rest, we call that sum of forces "zero".
Answer:
Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture is up) is limited by surface tension and, of course, gravity.
1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity
Answer:
T = 5.196 T₀
Explanation:
For this exercise let's use Kepler's readings, the third law is
T² = (4π² / G M) a³
They tell us that
The distance is three times greater
a₂ = 3a
As the satellite orbits the earth we use the mass of the earth
M = 5.98 10²⁴ kg
T² = 4 pi2 / (66.7 10⁻¹¹ 5.98 10²⁴) a₂³
T² = 9,898 10¹⁴ a₂³
T² = 9,898 1014 (3 a)³
T2 = 9.89 1014 a³ 27
T₀² = 9.89 10¹⁴ a³
T² = T₀² 27
T = T₀ √27
T = 5.196 T₀
The period increases by 5 times
