Kepler's laws of planetary motion best describes the statement
Answer: Foresters. Manage public and private forested lands for economic, recreational, and conservation purposes. May inventory the type, amount, and location of standing timber, appraise the timber's worth, negotiate the purchase, and draw up contracts for procurement.
Explanation:
Answer:
the maximum height reached by the marble is 11.84 m.
Explanation:
Given;
mass of the marble, m = 0.02 kg
extension of the string, x = 0.08 m
force applied to the string, F = 58 N
Apply the principle of conservation of energy;
elastic potential energy = gravitational potential energy
¹/₂fx = mgh
Therefore, the maximum height reached by the marble is 11.84 m.
Answer:
F_c = 519.32 N
Explanation:
We are given;
Mass of child; m = 27.1 kg
Angular velocity;ω = 31.6 rev/min
Radius;r = 1.75m
Since we want to find the force in Newton's, let's convert the angular velocity to Linear Velocity. The formula is :
v = r × RPM × 0.10472
v = 1.75 × 31.6 × 0.10472
v = 5.791 m/s
Formula for centripetal force is;
F_c = mv²/r
F_c = (27.1 × 5.791²)/1.75
F_c = 519.32 N
