Answer: in the Newton concluded that objects fall because they are pulled by Earth's gravity. Einstein's interpretation was that these objects do not fall.
Explanation: These objects and Earth just freely move in a curved spacetime and this curvature is induced by mass and energy of these objects. - I HOPE THAT HELPED!!
B is the right answer. Multiply numbers you get the answer
Answer:
0.975 m
Explanation:
The center of mass y = ∑m₁y₁/∑m₁ where m₁ = the individual masses and y₁ = the y - coordinates of the individual masses
So,
y = (2.02 kg × 3.03 m + 2.92 kg × 2.43 m + 2.53 kg × 0 m + 4.02 kg × -0.501 m)/(2.02 kg + 2.92 kg + 2.53 kg + 4.02 kg)
y = (6.1206 kgm + 7.0956 kgm + 0 kgm - 2.01402 kgm)/11.49 kg
y = 11.20218 kgm/11.49 kg
y = 0.975 m
So, the y- component of the center of mass of these objects is 0.975 m

Answer:
Water leaves the holes with a speed of 2.65 m/sec
Explanation:
It is given internal diameter of garden hose = 2.9 cm
So internal radius 
Number of holes n = 24
Diameter of holes d = 0.36 cm
So radius of holes 
Velocity of water in hose 
According to continuity equation




Therefore water leaves the holes with a speed of 2.65 m/sec
