The answer to this question is b
Newton’s second law of motion is force equals mass times acceleration.
F = m•a
An example of this would be hitting a ball. If you hit the ball, it will move however fast you hit the ball. The harder you hit the ball, the faster it will move.
hope this helps and brainliest please
Answer:
Option (B)
Explanation:
To measure the distance between two objects we use the units of length.
To measure small distances we use, mm or cm or m. But if we measure large distances between two objects we use large units such that kilometer or miles.
To measure the very large distances between two objects we use large units such as Astronomical unit or Parsec.
The Astronomical unit is defied as the distance between earth and Sun.
Thus, the distance between earth and the sun is defined as 1 Astronomical unit.
1 Astronomical unit = 1 A.U. = 1.5 x 10^8 km = 1.5 x 10^11 m

Answer: the equilibrium point or center of mass is (4, 7.33)
Explanation:
1) Physicial principles:
- The equilibrium point is the center of mass.
- Call Xc and Yc the coordinates of the center of mass (Xc, Yc), then:
- Xc is given by the equation Xc = (m₁X₁ + m₂X₂) / (m₁ + m₂)
- Yx is given by the equation Yc = (m₁Y₁ + m₂Y₂) / (m₁ + m₂)
2) Data:
- m₁ = 24 kg
- X₁ = 2
- Y₁ = 5
- m₂ = 12 kg
- X₂ = 8
- Y₂ = 12
3) Solution:
- Xc = (m₁X₁ + m₂X₂) / (m₁ + m₂) = (24×2 + 12×8) / (24 + 12) = 4
- Yc = (m₁Y₁ + m₂Y₂) / (m₁ + m₂) = (24×5 + 12×12) / (24 + 12) = 7.33
Answer: the equilibrium point or center of mass is (4, 7.33)
